Hello,
I have recently bought nexus one and now randomly I have problems with the screen - I click on one place and it does something totally differently. It is fixed if I turn off and on screen. Before posting the question I did do my homework - I found this
- Q5: Sometimes my screen registers touches in incorrect places, and I need to turn the phone off and on to make it work correctly again
A: This is a hardware problem, nothing can be done about it. Nexus One's digitizer sucks.
in FAQ and found out that screen can't be calibrated. Now the questions that I have are:
1) Do all of the nexus ones have this issue? Would you advice me to return the phone and get a different model or replace for the same model (I already have bought screen protectors and case).
2) How often does this happen?
3) Is this a truly a hardware issue or software issue?
If this is a hardware issue - can it be fixed by software (e.g. by restarting the driver for the digitizer every minute or something like that...). I've read somewhere on this forum (or on a different one) that motorola had similar issues and they have released a patch that has fixed the issue
4) Are their any hopes it will get fixed in future releases?
5) People who have the same phone - how often do you have to turn off and on it (the screen - not reboot)?
Any other issues I should be aware of?
About the phone - its android 2.3.4
1) Yes. Some are more affected, some are less, all have it. It also depends on a zillion of factors - including climate, average finger moisture, etc.
2) See answer 1.
3) I've never looked at the code, but Nexus One is out for a year. If it was possible to fix - I'd bet it would have been done by now.
4) See answer 3.
5) See answer 1.
You've done your homework, but still came to ask "just in case". Well, the answers didn't change for the last 1/2 year.
Thank you for the quick answer.
If all the phones have this issue - why people are still using them? Or this is something they have just got used to? Also I understand that the frequency is different for everybody, but can I please have some numbers? Its one thing if it does it once a day or once a week and totally different if it does it every hour or every 15 minutes of use... Can you please let me know how often it does it for your phone? Also are you using screen protector? Is there any corolation between screen protector and and frequency?
Screen protector is known to cause less sensitivity and less responsive screen, which might account for some of the trouble.
People got used to it.
It mostly depends on the moisture and heat - the hotter the phone, the more likely is the screen to fail. Without moisture and with casual use it'll fail once a day or so. When playing a game, it can fail more than once an hour.

It happens to all nexus ones, its a hardware problem. But it only happens about once or twice a week, so most people just live with it. Just turning off then on the screen fixes it, so only takes a second to clear the error.
Also heat seems to cause it, particularly when its charging.
I go weeks without ever seeing the issue. Other times I see it once a week. It sucks but not a huge deal really.
Hi guys,
Just a quick question.... if this problem is hardware and relates to the digitizer then is it worth just replacing the digitizer?
I notice you can purchase a replacement digitizer on eBay.
Is it worth a try? And if so, is the N1 easy to take apart?
I've taken other phones apart and repaired them so have some experience.
If you replace it all you're doing is waisting your time. It will be the same thing. It is not like the digitizer is broken/failing or anything. It just sucks. Its not broken. Better way of thinking of it is a hardware limitation.
Hi guys,
Well, not wanting to be beaten by this screen problem, having suffered for over a year, I decided to take the plunge and buy a new digitizer off eBay. Cost about £20.
Found a couple of vids on Youtube which show you how to take the phone apart etc.
Two months on and all working fine. Not one single screen issue since replacing the digitizer.
Now a VERY happy Nexus One owner. Just wish Vodafone or HTC could have done the same thing on anyone of those four occasions I sent the phone for repair!!!
Now also running the MIUI custom OS... what a fantastic OS!!
Well, I'm pretty surprised no one filed class action suit against Google or HTC for supplying faulty digitizers on Nexus One

wow! which seller did you buy it from? is it an OEM part or third party? was the multi-touch issue fixed e.g. X-Y axis all over the place when fingers come too close together? does it now register more than 2 fingers?
The seller on eBay was e_cell. Search for this item to see the digitizer I purchased: 190567591678
It was listed as: 'GENUINE HTC NEXUS ONE G5 TOUCH SCREEN DIGITIZER + TOOLS'
I used a video on YouTube to dismantle the phone and insert the new digitizer.
Search YouTube for 'Google Nexus One Screen Replacement & Take Apart Directions'
Sorry I haven't include direct links but the forum wouldn't let me.
Note: Once I'd taken the phone apart I ran a warm hairdryer over the old digitizer in order to soften the glue that holds it in the frame of the phone. Then I slowly eased the old digitizer out of the frame and inserted the new one. The original adhesive in the frame will hold the new digitizer in place.
Tip: Make sure you remove any dust or finger prints from the new digitizer before reassembling the phone. You'll kick yourself if you forget to do this as they will be visible on the inside of the digitizer and it will drive you mad! I made this mistake and had to take the phone apart again to clean it up. DOH!

I would love to know what sort of problems did the new digitizer fix?
My problem was when I touched one area of the screen another area would respond.
So a screen calibration issue.
It was most noticeable when texting. For example I'd press a key on the top row of keys and a key on the bottom row would respond.
A work around was to press the power button to put the phone into standby and press it again to continue using the phone. Sadly the problem would always come back.
I'd also have problems selecting App icons. I'd press one and another would respond.
I asked both Vodafone and HTC to swap out the screen but all they ever did was flash the rom or say they couldn't find any problem.
The issue I had is well documented on the internet.
So glad I never gave up on this.
wait so a new digitizer fixed the issue?
so theres a different version of this digitizer?
or is the model and product number still the same?

Do you have the part number of this new digitizer you replaced? it turn out there are a number of OEM parts with different parts number
Unfortunately I can't state the part number as I don't have that information.
I simply searched eBay for a digitizer and looked for a good seller who appeared to be trusted and had a good feedback rating.
I'd bought from 'e_cell' before and knew they provided a good service.
All along I knew I was taking a gamble when buying the digitizer but the problem with the phone was so annoying I decided it was my last hope to get the thing working properly.
I've had the phone close to a year and a half, and during that time its spent most of its life either away for repair (Vodafone or HTC) or sitting in its box because I refused to use it. Instead I bought myself a second hand iPhone 3G off eBay to get by. Things were made worse by the fact I am tied into a two year contract with Vodafone.
So trying a new digitizer was my last throw of the dice, so to speak.
And the fact it worked is brilliant. I still feel this phone (Nexus One) is the best phone I've had, and I've had quite a few.
Please remember... if you decide to do what i did then see it as a gamble. There are no guarantees in life.
Oh, and be real careful when taking the phone apart and reassembling. It's not particularly hard but there is always a risk you may damage something. So be warned.

Thank you for the information, so it turn out nexus one have quite a number of unresolved issues. I was wondering why didn't big G did not order product recall for people with faulty digitizer?
I looked around and found that a number of users have having all kind of issues after replacing the digitizer. Geez...what should I do? Perhaps I should take it to a professional phone repair shop?

Well, luckily for me no problems as yet (though never say never!).
The most important thing when taking the phone apart is to take your time, and memorise where everything is located. Be firm but not heavy handed. There are some delicate parts inside the phone so you have to be careful.
Common sense really.
I've had no issues with signal strength. I get HSDPA most of the time, or standard 3G. My data (internet) is working fine and so is GPS.
Inside the phone there are a couple of connectors that control signal so you have to be careful and make sure if they disconnect that you reconnect them again properly.
I build and repair computers and laptops. If you've ever taken a laptop apart that has wireless LAN capability then you'll know there are specific wires which connect the antenna to the motherboard. The same applies in the N1 but on a smaller scale.
Good luck to anyone who tries this!
does anyone from the UK have a source to get a new digitizer from that fixes the heat related issue?
ebay has one for £22.50 (id: 10goodseller2012), and i'm almost ready to click BUY, just want to see if anyone else has more info before i 'blindly' click buy...
edit: i should add, 'e_cell' seller no longer has the N1 digitizers listed...
No matter what anybody says, replacing the digitizer itself won't fix the issue. It is deeper than that. It is the digitizer mixed with the onboard hardware to interpret the digitizer inputs. Usually it ends up just being heat related. I haven't had the issue with my phone for awhile, but that is because it doesn't get as hot as it used to with older versions of CM, but if I have it in the sun, in my car dock, using GPS, it will freak out all the time.

i too was sceptical, and i still am.
however, I've replaced the digitizer and so far it's perfect! i'm not sure it's placebo as i could get it todo it 100% of the time.
prior to ordering the new digitizer, i ran tests to see at what temp ranges the screen would play up - according to the battery temp (Battery Monitor Widget), it will play up over 40c.
what i SUSPECT is the fix, is the digitizer i bought is a newer hardware revision than the one i had. the new digitizer did come with it's own chip on the flexible PCB.
i did mean to write down the new digitizer number and compare from the old one to see if they have revised it - alas, i forgot to get the new number. (old one is 940-473-1r5)
its been installed for almost 2 hours now, and on test for around an hour to build up heat - screen on full, camera on, GPS on (using aLapRecorder HD) and it's perfect. before i could guarantee a problem with screen dimmed, camera on, GPS off, so early impressions are good!
I'll give it a proper test tonight on the way home from work - it'll have the windscreen blower aswell..
Hello,
so today I bought a second-hand LG optimus black that was soft-bricked and had a cracked touchscreen. Since I'm not new to android and know how to fix these things, I thought this was just another way for me to get a good phone cheap.
The problem is:
- after unbricking the phone, and installing official v10a software, there are issues with the phone - camera force closes, any of sd cards wont be recognized ("removed sd card, insert a new one" notification, never changes), the screen rotation doesn't work, there is no lockscreen, phone dialer has lags, and the screen turns on after 5-10 seconds. Otherwise it's ok.
With software v20b it also likes to hang up. Theeen you have to remove the battery
So I dissasembled it, and it seems to have short circuited somewhere on the motherboard (there is a brown spot on the metal motherboard cover plate).
I marked the area in a picture below (notice that it's right next to the SanDisk chip - i guess that organizes the memory, so it should take care of the sd card as well). Keep notice this isn't the picture of my motherboard, I will post my own photos a bit later..
Maybe it was waterdamaged, but the sticker on the battery is white :/
Please don't tell me to factory reset, or try other software or memory cards, already did that.
CWM won't detect memory cards as well.
I need any possible ideas to fix it.. do you think a reflow would have any chances to do the job? any ideas, please, will try anything..
PLEASE, help.
Some update. So I flashed software V30B, and it seems to get better - finally I get a lockscreen, and not in 10 seconds also, the accelerometer sensor is working, phone is smoother. FRONT camera is working as well, while in video call mode, yay! when turning on the camera, it has a black screen with all the buttons and camera settings, and a message that there's no sd card (although it's inserted :| ) and hangs up if I switch to front camera. Memory card still not detected..
Thinking of capturing a video to show you whats the situation.. Till then here are some photos to show you my beauty
P.S. don't be shy, guys, any ideas for fixing?..
the photos
Anyone?
I thought I would get some replies, at least maybe I was wrong

i am sorry, but ppl in here(p970) isnt as good as ppl on s2 or s3 thread.......
maybe on s2 there is chainfire, that undrrstand phone by hardware and software....but here....even development is on "almost dead" stage.....no stable cm, even cm7.....so sad.....
so....dont expect professional answer soon.......
and btw..try your luck on android hardware hacing thread....maybe there is some answer for you there

Thanks for the reply!
Well I thought I would find more hardware technicians here, but whatever..
I downloaded the service guide for optimus black, and after looking at the schematic sheets, I'm 90% sure it's "SUB PMIC CAM POWER (LP8720)" controler that's failing. It controls the 5mp camera, microSD card and motor driver (vibration) power supplying. Neither of these functions are working on my OB. So no need for hardware hackers, nothing new they can tell me. So I'm thinking of ordering this pmu, but could you tell me guys where I could get it from with normal priced shipping? Shipping time wont matter at all.. Digi-key and mouser want to charge me with 40$ shipping, while all I need is a 2$ part

Makes sense. Most people don't believe that ICs are a very sensitive component.
Obviously, I can't make a theory of what's wrong on that device, as I don't have it here.
Do you have a multimeter? On the service manual you might have somewhere what to do (e.g. where to measure voltages) if some functions are not working, or did you already try that? I know the service manual always ends with "replace pcb", as usually the technical support don't actually do the repairs, they just follow what's on the manual and send the old parts to the manufacter for repairing and reassembling, but it might help you understand if you really need to replace this IC. Is there any fuse nearby, for example? Remember, a short circuit would break fuses. You can check with a multimeter whether they're damaged or not (continuity test).
There's not much I can say, really...these are just some suppositions...
Good luck with that, man

I do have a multimeter, I'm kinda into electronics so..
Yeah, so I had a little break and checked the phone out only a few minutes ago.
The LP8720 is the problem, but its much more f..ked up than I thought..
I marked three spots on the circuit that are quite odd:
1. The place where IC U601 - LP8720 should be.
2. 2.2uH wire wound resistor L601 (MIPSZ2012D2R2 MIPSZ2012D2R2, 2.2 uH, N,2.0X1.2X1.0), not sure if it works, maybe it burnt out, my multimeter shows 0ohm on this one.
3. The place where capacitor C604 (10uF) should be.
I attached the pic of my motherboard, you'll see whats up..
The only place I can get LP8720 is alibaba.com, and the minimum quantity is 10.. that makes about 16 bucks for these. Would be worth buying and trying to fix? And another thing, it's named LP8720TLX-B, not LP8720TLX. Do you think it'll do?
I'm now thinking of taking it to a service center, ask if they could do such a job and how much would it cost..
Thanks for the replies, by the way!
Peace

Hey man,
keep an open mind
What makes you so sure that this IC is damaged?
Think: if the nearby components are damaged, then this IC may behave differently (or may not work at all). We don't need math to think this.
But yes, it can be damaged, but since this is the most expensive component, I think it is really worth checking the others first.
Anyway, answering your topics:
1. Everything looks fine. Good ^^
2. Yes, it's probably damaged. An inductor is supposed to have resistance, but not much. For this one, 0.23 ± 30% Ohm.
Source (datasheet): http://www.fdk.co.jp/cyber-e/pdf/CD-TCE070.pdf
3. Fortunately, this is an easy one. If in doubt, just replace it.
Now, for the headache...LP8720TLX-B and LP8720TLX might be the same IC, but the only way to know this is by comparing their datasheets.
16 bucks is a lot to pay for a component (yeah, it's 10 of them, but it's still a lot). But this is actually your call...are you willing to pay 16 usd for an IC? If it was me, and I was entirely sure it would fix everything, I would probably buy them, but then...like I said, your call.
I think it's worth taking it to a service center, but if they truly follow the service manual, they will tell you they need to replace the entire pcb. But I really think it's worth to try, you never know.
Good luck
My Note 8 mic died today :crying: I can hear the callers but they can't hear anything from me. If I switch to speaker, they can hear me. I checked all settings and did factory reset, didn't solve the problem. I took it Samsung service center at Rama 9 Bangkok ( I live in Thailand). They tried "deep" re-flash (whatever that means), but didn't fix. Seems like my phone failed their diagnostics as well. They opened up the phone and confirmed it's a hardware failure. Fortunately, everybody who preordered Note 8 over here get 6-month brand new unit replacement and 1-year accidental screen damage warranty as part of promotion in addition to free AKG 230 blutooth speaker, some military grade cover, pencil style s-pen. So for this case, they processed mine to get brand new unit as replacement. I have to wait 7 to 14 days. I really hope my replacement phone will be problem free.
I'm just glad I haven't purchased whitestone and only bought some cheap screen protectors. I was also considering of rooting it. Now that this happened, I don't think I'm going to do it at least until my warranty runs out. I really don't want to lose my accidental screen damage warranty. I have a feeling that I'm will be using it.

Always sad to read this sort of post. As you know there will always and I mean, always be lemons. Try not to let this sour your Note 8 experience though. I do hope you get this situation resolved in a satisfactory and speedy fashion.
Let us know how you get on. :highfive:

The weirdest part is that the mic is the same either for regular call or speaker, the only thing that changes is the output audio source...seems more of a software issue than hardware, that for some reason is not opening the mic on regular calls...[emoji848]interesting...

Do you have a case on it? Take it off.
I ask because I first used a hard case and the mic didn't work always...the bottom port seemed partly covered, not much but obviously enough. Take the case off and all good. I now use a goospery soft case and it's fine.

The weirdest part is that the mic is the same either for regular call or speaker, the only thing that changes is the output audio source...seems more of a software issue than hardware, that for some reason is not opening the mic on regular calls...[emoji848]interesting...

While I don't know which microphone is used for what, I'm pretty sure Note 8 has 2 microphones: 1 on top and 1 on bottom, so maybe it is using top mic with speaker on, not the bottom one?

Update. I got my sealed brand new replacement couple days ago. My new phone is manufactured in Sep 29th. Everything is good. Mic is working. Screen is good, no light bleed at all. They even unboxed and did diagnostic of new phone with me, mainly checking the screen for any dead pixel or touch sensitivity issue, before I signed paperwork. I'm super happy with Samsung Thailand services, far far better than in the US.
Now let's see if I'll ever have to use 1-year free screen replacement. I nearly dropped it this morning.
That's a hell of a promotion. Wish we'd get that here in the States. The Galaxy 360 camera I made the mistake of choosing (instead of a sd card/fast charger) is a piece of doodoo.

My wife got the 360 camera during the S8 promo for a "mere" $50 extra. It's still sitting in the box and not being used. Waste of money for us it was.
Was actually thinking about using it. , Does it have any real uses ?

Mine is giving trouble too, but the entire circuit board there seems to have died on me after about a week, the LTE strength suddenly became terrible, and I found that if I applied pressure on one of the antenna connectors in a specific direction the strength would jump up to normal.
I'm waiting for replacement parts to be available, and I noticed that the USA version that ifixit has a teardown guide for has a newer revision of this board, made a week or so after mine. Must have had some of the early ones fail prematurely... The rest of my phone works flawlessly, fortunately.

Yes. Put it on Ebay and hope some poor schmuck pays you your $50 for it.
Op, that is the reason to buy only from authorized official dealers! The people who get their devices in grey markets most of the time have troubles with warranties
I have the same issue, blowing into the usb port seems to fix it temporarily. Hope this gets sorted out with a software update.
Hi guys. I recently used a questionable charger with my phone (leeco le 2 x526) and since then it has been problem after problem with the USB port. Immediately after that charge, the phone stopped charging with the supplied quick charging brick. It won't even charge slowly. The phone behaves like the charger is being plugged in and out about five times and then completely stops as if the charger is no longer detected. However ,when I put it in a normal slow Samsung charger, it charges to the end without disconnecting.
It's not only the charging that's not working. A Windows PC I have connected the phone to before doesn't recognize it so mtp doesn't work. The PC says the device has malfunctioned and windows does not recognize it. Lately the phone has started rebooting randomly so it seems like I need to fix it soon.
Also, when I plug in headphones using the 3.5mm dongle, I hear crackling sounds for the first few seconds and Jack detection doesn't work sometimes until I reboot. Sounds play okay when it's detected. The microphone and media control buttons on headset have stopped working and I hear static when I press the buttons on my headset, sometimes it's quiet.
I'm pretty sure the USB board is the one that's damaged but want to know if anyone else has faced this issue. If it's the USB+mic board that's damaged I'll order one on AliExpress. I found it for like 8 bucks.
I'm thinking I have a hardware failure because since it started acting up, I tried to flash a ROM clean and got an error in TWRP. The flashing finished but I saw a red error message:
Code:
rcv error in uevent
I googled and this error occurs when the kernel fails to initialize a hardware component.
Has anyone experienced the same problem? I don't want to replace the board without a second opinion.
I believe that you are definitely on the right track with the replacing board, this same exact issue happened to me once on my first Leeco X727. In my case I was lucky enough that Amazon agreed to exchange it for a new phone. Without a doubt, many Le Pro 3 owners have seen this exact issue. Your questionable charger possibly shorted out the USB card.
I would strongly suggest that you replace the battery, while you are at it, it will also be very cheap.
You will need to use a Heat gun to remove the display without damaging the LCD, there are many videos on youtube that demonstrate the quick sweeping technique and the glue will easily release enough that the screen will come off simply by turning the phone onto its face side.
While you can also use a hairdryer, you will need to run a guitar pick along the edge of the screen to remove the display and it's very easy to damage the LCD...I did! Consequently, I bought a heat gun at harbor freight for $ 7 dollars, to easily the display on a friends X720.
Good Luck.
PS : Did you receive your Le Pro 3 yet?

Thank you so much for this advice. I will replace this board and see if it solves the problem. About the heat gun, I don't know if I will use it much after this repair so I'll take the phone to my friend who has a repair shop to change it for me.
One quick question... Is there a high possibility of damaging the battery during this repair? I don't want to replace it if I don't have to because mine is still pretty good and keeps like a new one. I don't have much luck with AliExpress because the original batteries for Le 2 cost almost $150 to ship. The rebranded batteries cost less to ship (~$10) but I don't know which one is reliable.
My Le pro 3 is still in transit. I reckon it's still about 2 weeks away because shipping takes very long to my country. I'm just now going through the various development threads to find a good ROM for it. Thanks again -- you're a godsend ???.

No problem.
The battery is underneath the heat shield so it will not be affected by the heat gun.

I flashed a ROM from 4pda and totally messed the phone up. That ROM failed to boot and to make matters worse, it formatted my data partition. Everything is gone including my backups and I cannot transfer a new OS to the phone because my USB port doesn't work. The only thing I can do now is to shelve this phone until the replacement USB board arrives. You have been of great help and I appreciate it extremely. I'm using a feature phone now until my pro 3 comes. To use any Android app I have to share my wife's phone which just sucks. (She barely puts the damn thing down)

You will definitely love the Le Pro 3, it is much more powerful, and the camera is phenomenal.

Absolutely true. I have a new found appreciation for my phone. Now that I think about it, with the time I spend on it I think some digital detox is in order.
I received the USB board from AliExpress but it is incompatible with x526. Anybody with information on where I can get a board for x526 please share it here. All USB boards on AliExpress are for x620 and they can't work on x526.
I am actually thinking about looking for the x526 board in India because that's where the phone was built for. I just haven't figured out how to go about it. But I reckon there is a lot more need for spare parts there because of the high number of people using the phone.

My le 2 is finally back to full working condition thanks to you. This USB board doesn't look used at all. The best part is that mtp and fast charging are working again.
Hello guys,
I have an old Samsung GT-i9060 phone which I'd received from my previous employer. It has finally given up and is now completely dead. I suspect a faulty charging cable to be the culprit this time as my attempts at superficial repair has proven that the problem is deeper. I tried getting it fixed at a local repair shop but he gave up on the basis that parts aren't available and that the motherboard has gone kaput.
So, to summarize....
Samsung GT-i9060 completely dead
has been dropped several times and cracked digitizer has been replaced.
old battery is not at optimum condition but problem persists when tested with a new battery.
No vibration or samsung/charging logo on display when powered on battery or charging but certain areas of motherboard get heated up if I try to turn it on.
I got some important contacts and backup on this phone which I'd really like to salvage. I invested in a few basic tools and looked up a few tutorials on the interwebz but none seem to help me understand the actual problem. I am a novice when it comes to electronics and can easily try to recover the data through some specialists but the satisfaction in getting it done myself is priceless!
So any kind of help would be immensely appreciated.
Thanks
Make sure that the battery voltage is over 3.6 volt. Then connect phone to pc using usb cable without pressing any buttons then check pc detects phone's soc(broadcom interface) or not.
Thanks. Let me try that out and get back to you.
Update - @engage4 Battery was at 4.27V, fully charged. Connected to PC but it wasn't detected although I observed the same heating issue as mentioned in my original post (see attached pic)
Coincidentally, the memory chip and processor are on the exact underside of the mobo area that I have highlighted (which heats up)

So you already tested with a new battery. Good! That's one of the first things I would do as well. GSM Arena says the battery is "Li-Ion 2100 mAh, removable". At least you didn't need to send it in or leave it to a repair shop to replace the battery. I remember the time when you could replace the battery of your phone yourself. That in itself was very satisfactory. Those were great times! Those times are gone. Now you have to pay a premium to replace a battery. It's "complicated" they say, and so it's not for everyone (or anyone).

Hotter than what's usual for a phone that's charging? If it's shorted, charging may damage it further. You can test it of course, but you're risking it. Don't test charge for longer than you need to, preferably not at all as soon as you realize there's something wrong with the device. There's the risk of battery leaking or catching fire. So be careful and don't leave it unsupervised.

What kind of tutorials are you reading or watching? What do you think is the problem?
You have to go over more than a few tutorials if you want to be able to intuitively know what to look for or what to do. One way is to start learning about electronics in general, experiment and learn, before you get down to this specific problem. Another way is to start exploring from the repair side of things and work your way into the topic of electronics repair by troubleshooting this specific problem.
Your problem is most likely caused by a short somewhere on the board. So I would suggest you learn about short circuits or "shorts" for short (duh) and how to find shorts in general, and then work your way down to how to find shorts on mobile phones specifically.

I know that feeling. I'm wired the same way. If I can, I will try to repair and fix things on my own. Sometimes I will take on things I hardly know anything about. I will try anyway and learn in the process. Some things are admittedly more difficult than others. But that's how you learn and grow your knowledge base.
People no longer repair things. They throw out the old and broken things, and just keep on buying new things like on conveyor belt. This is not good in by any means. The biggest negative impact of this I think is that people stop using their head. They begin to believe that everything in the world is automatic. A light bulb is the result of true magic, especially when you throw in smart home plugs and switches into the equation. People are slowly being turned into slaves of consumerism. Common knowledge diminishes, like what household products you can use to remove stains, and we only live to serve a higher purpose of capitalism.
Do you have the service manual for this phone? You can usually find these online free of charge. Do you have a multimeter? The first tool you should buy and learn to use is a multimeter. Learn about the continuity test, diode mode, and how to measure voltage.
I worked as an electrician and I felt like I had to ask about how to measure voltage at a resistor, because I was unsure and didn't want to risk damaging a board more than it already is. As an electrician, I worked with voltages relative to Earth ground. I never worked with electronics, although I did get basic electronics training and I know all the basic components and how they work. We worked with soldering iron as well, and learned to use an oscilloscope. I was best in class at soldering. This was a long time ago though. We programmed PLCs, made Delta and Y-configuration connections of three phase electric motors, worked with relays and contactors, and we learned a whole load of other useful things.
My point is, always ask someone more knowledgeable and experienced if you're in doubt about something, rather than taking a risk or gambling. This is much more important of course when working with unforgiving high voltages and high currents, so as an electrician I learned early on to respect electricity. This was all part of my training and thankfully I have never had any accident. It's OK to make mistakes, and you're bound to make mistakes when experimenting, but you better have a backup plan and put in some kind of safety net, to protect yourself and to protect your equipment or whatever it is you're working on.

The USB connector on the charging cable I was temporarily using sometime back had a flimsy connector and I suspect the loose connection might have caused 'spikes' and maybe shorted some components/mobo.
I had dropped this phone on numerous occassions and almost everytime the ribbon connector for the LCD would come loose since the connector on the board was a bit wonky. I used to check this and get the phone working again. This is what I meant by superficial repair.

Thanks for clarifying.
Now that you mention it, one of my charging cable was a bit flimsy as well. Might be what happened with my phone as well. The connector would wiggle left and right so I would have to make sure it points straight into the port and rotate the phone left and right to make sure it's not tugging on it as I put it down on a book shelf. I always charge my phones on this book shelf as the power outlet is close by.
I have actually four identical Samsung 15 W chargers sitting there, all for the Galaxy S7. Three white ones and one black, and each with its own charging cable. I had purchased some extra chargers just as spares, and one of the chargers had a bit flimsy connection, as you say. I actually once spotted that one of the 4 pins on one of the charging cables was too short, and because of it, it was not charging fast enough. I stripped it down to bare wires, all for science and learning, before throwing it away.
On another occasion, I discovered that one of these cables didn't want to charge my phone when combined with one of the four chargers. It was a perfectly fine looking cable. The same cable worked well on the other three identical chargers though. So this was a bit of mystery I had never seen before. That will remain a mystery. That same charger also worked well when combines with other cables. So both the charger and the cable worked well, but only with others, not with each other. Note that these were all original Samsung chargers and cables. The "travel adapter", model EP-TA20EWE. They all came in original Samsung retail packaging. Although the spare chargers I purchased did have a bit stiffer and thicker cables, when compared to the original that came with the phone. They were presumably made in later years, so Samsung had probably changed them up a little bit.
But this goes to show that there is more to a cable and a charger than meets the eye. I suspect it had something to do with lack of compatibility across the many charging protocols that are in circulation in the fast charging universe, like Qualcomm Quick Charge 2.0 vs. 3.0 vs. USB Power Delivery 2.0 vs. what-have-you.
So you're not wrong to suspect something as "simple" as a charging cable. Not even a cable can be left alone, they have to make it "smart" and complicated. If the cable doesn't know how to talk the language of the charger, it's useless. Or worse, it can destroy a device. All because industry wants to satisfy inpatient people that want fast charging, and so instead of 1 standard, they make 4 different ones, if Apple Lighting-whatever is included. By the way, the faster you charger a battery, the faster it will lose its capacity and die out.

That depends where you look and how determined you are.
I ordered a new S535 power IC for my Galaxy S7 from Germany via Ebay, and I received it last week. I don't have the exact dates, but it arrived within the same week, so about three to five days. From Germany to Sweden. I also ordered three of the same chip from a supplier in UK, also via Ebay, and it has yet to arrive. This has to do with Royal Mail strikes, so everything is delayed. In addition, I had to pay customs fee and import tax from the UK. Not sure if it will be held at Customs service and delayed even more because of this, or if it will be delivered straight to my mail box since the UK supplier made sure I can pay upfront so it can be cleared for delivery. So I will have 4 of these in total.
Let me give you another example. I have an older car that's well looked after and only driven occasionally. A few years back, it started leaking oil from the rear axis. I went to the authorized repair shop. They told me they had to either replace the differential or rebuild it. But because it's an old timer, there are no parts for it readily available. This is a BMW car and BMW has a good reputation for stock keeping parts for old models for a long time. Well, maybe they don't keep a stock of big parts such as differentials. But it's not true that it's not available. I looked it up online and found several car stripping companies that have a number of these parts to pick and choose from, some of which were in almost new condition. So if they really wanted to, they could have ordered in from there. This is where small and independent auto repair shops order from as well. I even offered to order it myself and deliver to them. But they could not make the needed arrangements. Or rather, they didn't want to. I understood the message. They can't be bothered with something as heavy, oily, dirty, difficult, skill demanding, and time consuming as a differential replacement... and a rebuild is probably as distant as science fiction to them. I never went back there. I used to go to them for years and was always happy. Since they changed the owner and relocated, it's a completely different company. I would never again go to an "authorized" repair shop. They are properly titled "car dealers", because they are more interested in selling you a new car or a used car than repairing your old one.
It's the same with phone companies like Samsung and these places they call "Support Center" where you can walk in to get support and service on the device you already own, and they put up their latest "flagship" models on display and under your nose. That's how you know you're in the wrong place. It's all sell, sell, sell.

Make sure to get the needle-like test leads for it. This is needed for probing and measuring tiny components. The ones that came with my multimeter were very good, but they were not fit for the job, because they are not thin enough at the top. Most of the standard test leads have blunt tips. I ordered a pair from Amazon, a complete kit actually, but they are not very good. The whole kit was very cheap and I could not find any other, higher quality, more expensive ones. I don't want to promote Amazon, but I can post a link if you want.
A heat gun might work, but a hot air station is better. You need about 350 C to rework big components like BGA chips. Based on my limited knowledge, but extensive research. You should be able to tell what the temperature is at, and only the more expensive heat "guns" will have a temperature sensor and a digital display.
A service manual is a good resource. I wish I had a complete service manual for Galaxy S7. I looked for a places to buy one but I only found dodgy websites that seemed to be in the business of downloading free manuals, packaging, and selling. So if you have a complete manual, that's better. I only found excerpts of the most important chapters for Galaxy S7, and it has been very useful.
So, umm, there has been no progress on the repair front as I had been away on a trip and got my phone stolen
I was a bit occupied with reporting to the authorities and blocking my phone number hence I couldn't reply earlier.
Btw, I stumbled upon something called as boardview bitmap files; I'm yet to fully explore it but it seems really helpful.
