Fell from 1.5mts height - Camera - Recovery - NOT Working - Nexus One Q&A, Help & Troubleshooting

My Nexus One Fell from a height of approx 1.5 meters.
> Now the charging LED is not glowing.
> When i turn on the Camera, the screen completely goes BLACK for about 1 min and then say NOT RESPONDING
> When i dial/call some number i can hear the voice , but the screen goes blank and i cannot hang up the call.
I wanted to Re-Install my OS, but i am not able to enter the Recovery.
I am using 4EXT Touch, the screen stays at the count of 0 and keeps looping there.
I even updated the newest Recovery using the 4EXT recovery APP. but No use.
These are the problems i so far found.
The mobile fell just a few mins back and i am very concerned :crying:
Please help

Seems like all the TOP portion things are not working.
The Proximity sensor is acting ODD.
Some times it does not Turn off the screen. SOme times it does not turn on the Screen.
Please reply.
How to Flash the ROM without entering the custom Recovery ?

I disassembled the mobile and checked if there are any loose connectors but didnt find any.
Please help me

"Fell from 1.5mts height"
AND IT WORKS?!?!?! No broken screen!?? Miracle!!
Best chance is to get a cracked screen/digitizer one on eBay, should cost around $20 or so, and replace the motherboard + camera.

The mobile was having the Silicon Cover so i think it absorbed some force, but some internal parts might have been effected
I dont have any problem with the TOUCH. It works well.
I found no loose connections in the connectors.
Non working things are :
1. Ear phone socket - Does not detect the headset
2. Camera - shows blank screen for a few secs and force closes
3. Proximity Sensor
4. Charging LED
so far i found these issues.
I cant enter the Custom Recovery (4EXT) too.
Please help me.

Sounds like you've damaged quite a bit of it. It may not be the motherboard that's the only problem, and could mean also replacing screen, etc. Unless you're up to that it could be time to let the Nexus One go..

As of now it started to Switch ON. So it is better than not having it at all.
All the above noted issues are still not working

I'm sure some items aren't absolutely necessary such as the charging led, but the earpiece and the proximity sensor could be more the problem. At least it boots - better that than nothing at all

Take a look on eBay - there are some ear pieces available (at least in the UK) and proximity sensors. Then if you follow a video which you will likely find you can manually replace these parts to see if they are the problem

Had the same problem; it can be the ribbon cable which is either loose, or completely disconnected. The bad news is that you'll have to disassemble pretty much the whole phone. We've actually damaged one the of the cables once while trying to do this, so if you try it, be very careful! There is a page online somewhere that tells you which cable it is exactly, just search the symptoms:
1. Camera doesn't work
2. Charger LED doesn't work
3. Proximity sensor always shows "near", as a result -the screen remains black after making a call
UPDATE:
Found the link with the picture of which cable it is:
code.go ogle.com/p/android/issues/detail?id=15291
It's a long page, so just scroll down

My Nexus one also has the same issues!
I know that it is coz of the flex cable. the other thing that doesn't work is the camera flash (when you try to use it as a flash light)
luckiely for me the ear phone does work! i am able to use the phone (except for the camera and flash light) for pretty much everything
as i always make/answer the calls using the ear phones, i dont have to worry about the proximity sensor not responding during the calls.
My suggestion would be to try and see if your ear phone is detected or not (may be play a song) and then use it to make some calls.

Unfortunately its not working. I thought i can atleast use for media listening/watching but its not detecting the earphone
there are some dedicated ROMs for usage as Media Players so i thought of it, but no use.
Only possibility will be to use the Bluetooth Headset. (I have Plantronics Backbeat 903+ but my ears pain a lot , doesnt fit will )
If some one can confirm that it is related to the FLEX cable then i can dare to buy it

ques
I had same issues as you.
Basically flex cable is loose and it needs to be attached properly. I have gone to service center and they dis-assembled and corrected it.
Proximity sensor ->camera not working. I can confirm the problem (happen twice to my n1)
@OP: I saw your post regarding NexusOne having booting up on Safe Mode: due to getting wet in rain.
How to resolve it. I am facing safe mode boot up issue. ?

RE: Safe Mode...
I've had this before, all I did was to take my N1 completely apart, until the point where I couldn't see anything else to remove lol!
I then left it to air for the next 48 hours, reassembled and it works!
BUT !
I warn you, if you do this, you MUST make a note of where every piece on your phone goes or you'll regret it at the end!

[Q] Screen sensor bug. Please help

Hello,
After a month of using Note, I take the bug, that make device unusable. Touch screen press themselves, without of contacting of my fingers in the left bottom corner (near button 'z' on screen keyboard). And it become more and quickly.
But this problem have the "solve": when I connect the phone via usb and charge it, bug falling away. But if I disconnect, they return.
I try a lot of roms and kernels, but problem have not solved.
In the program "Multitouch vis test" i find that sensor take pressure in pixels placed 1108-1109 y and 95-120 x coords. So, maybe I can stop processing of touch sensor in that rect? How can I do that and can I do that at all?
Maybe charging let the screen sensor to be less sensable? Can I do this via programm (or kernel)?
And I don`t understand is it the problem with screen sensor or usb?(usb module is mush sheaper).
Sorry for long thread and bad English.
Thanks in advance, Giggsoff

Thanks for links, but it don`t solve problem.
I record video, with my phone. May be it describe my problem

Just saw your video.
Looks really weird.
How long does this bug exist? From the beginning?
your sensor is very sensitive
I got that after month of using (two weeks ago) when playing "Order & Chaos Online", or maybe I start notice that. In the bottom right corner of screen (in landscape orientation) the button, that mean fire, was located. So I press it fast. But I get massages "select the target" when I don't press any key.
I was in hospital, when I notice problem, and it didn't falling away, when I connected the charge. But when I back home, connect there phone to charge it is disappeared. I mean, that it was result of my operations (I open the phone and clean, reinstall os), but it was only because I had connected the phone. Now, I try to use S-Pen, cause it lock touch screen, but it's hard and don't a way out. So I am going to return the phone. It's hard, because I am an international buyer - from Germany to Russia. Intresting thing - when I open my box I see, that on charge was words in Russia (maybe cause in it )
It's going crazy
Returning it back is a good solution, I think.
It's definitely a hardware problem.
Ok, thank you. I will do it next week. Sadly lose that amasing phone for a month or longer, but I shall have to do it.
When I had returned my old Galaxy S it just took 10 days until I got it back, so let's hope the best

[Q] Camera, LED, headphones not working. Hardware issues?

My girlfriend's N1 has gradually developed some problems. At first the headphones were not being recognized properly. Then camera stopped working. Now that I've taken a look at it the flash light does not work either. If you call someone, 4 times out of 5 the screen goes blank and you cannot end the call. Sometimes this happens when receiving calls as well.
I was using CM7 before and no additional apps were installed. Tried with or without SD card, rebooting, resetting to factory defaults, putting another ROM, restoring to factory ROM.
The symptoms:
- any camera app starts with a black screen and later throws wait/close dialog
- flashlight apps seem to work but no light is coming out
- headphones do not get recognized, tried 4 brands, compressed air, pushing, pulling, pressing. Not a lint issue.
- immediately after pressing a call I get a black screen which I can come out of by pressing a random combination of keys
I tried moving the camera and LED modules with my finger but nothing happened.
Everything else works: calls, trackball with led, bluetooth, wifi.
I had a similar problem with the flash and camera and it was fixed when I swapped out the main board which also has all the ports your having problems with

That sounds unfortunate because the original seller has now closed the shop: site is offline, amazon and ebay products are delisted, does not respond to email.
Even worse, I'm located in Germany and bought the phone here, but I don't really speak the language well enough to contact consumer protection authority and even the HTC support site is all in German. Original box and warranty are in my home country. Sounds like a recipe for disaster.
I've written a mail to HTC support since GooglePhone has closed shop as well.
Since I'm still on a rant, touchscreen has been acting up since day one, upon heating it registers wrong touches, but this is already a known issue.
It was a nice phone while it lasted, but in hindsight I wouldn't recommend it to anyone anymore. It still looks like new fwiw.

Hardware
Its hardware issue caused mayb y dropping the N1
so try to replacing ur main board or mayb u can get it repaired if u have a good engineer around u
Thank If my reply helps u ..
Just as an update, the issue with all these phones is the ribbon cable connecting headphone jack, camera, proximity sensor and perhaps [front] speaker. It's probably an easy replacement and the part cost is around 25-40$. The cellphone repair guy said that he has done it a lot of times for this phone type, so it's probably a production/engineering issue.

Screen does not shut off when in call.

My phone ever since I got it has not turned off the screen when in call. my cheek keeps pressing against the screen and presses thing while in call.
What allows the screen to know when to turn off? eg.sensing cheek on screen or the light sensor being covered up or the way the phone is held.
Is there a setting I should look into?
I have the phone as: rooted, s-on, faux kernel, ruu rom, twrp recovery.
Thanks
Also when I put the phone face down to activate the speaker, the speaker does not turn on.
I went to this site: htt.....p://androidforums.com/htc-vivid/606680-screen-shuts-off-during-phone-call.ht....ml
and they said that it was some corruption with the phone. I hope that not the case and that there is a fix.
If you can't solve this problem try to go "Phone" app then press "menu" then "settings" then find screen off when phone or type of,and put a check! Or if this can't to help you, take wet wipes and clean the part where the sensor is located! NOTE: If you have screen protector take away your protector and clean there then call and try without screen protector!

Remove your screen protector then clean the entire upper part of the phone to the middle. Then try to call and tell me did your screen shut off

It didnt work. actually the feature where i flip the phone upsidedown to activate speaker phone during a call doesnt work either. I think sense is messed up. It used to work though. I am stock with faux's kernel at the moment.
I did check the setting for the phone flipping and its enabled too.

The sensor is located at the upper left side of the screen and detects changes in light, I'd recommend u RUU, try to see if the sensor works and the flip for speaker and then root again cuz it could be an unidentified bug of that kernel with that specific stock rom.

I also tried using the app to recalibrate the snesor but it doesnt work, gives me some polling error. (http://allmobilsoft.com/android/a_system/2177-dhd_proximity_sensor_recalibrator.html). I also got a app from the play store to recognize my sensor, but my sensor is unresponsive at 9cm. im not sure if the app works or not on htc raiders. (https://play.google.com/store/apps/...xLDEsImNvbS50aWdlcm1vbnN0ZXIucHJveGZpbmRlciJd). maybe my sensor is busted. I know if the sensor starts working then the screen will turn off during call and the auto speakers should work. so I managed to nail down the problem maybe.

Ahg my friend then it sounds like your sensor is messed up, since you flashed the ruu maybe, if you have warranty they'll give you another vivid cuz it's a hardware error from what I understand. And yes that app is compatible with the vivid. Also they don't check the bootloader when its a hardware error so if they ask you if you rooted your phone, say no, but make sure you've relocked and flashed the ruu. Normally if it's your firs incident like this, they replace your phone for free. Good luck

Actually i think htc directly can help you with that, I dont know about rogers, but when I had my evo 3d I had problems with signal and they told me it was hardware malfunction and told me and told me to call htc and they did help me with the issue. it was two years ago though but you should give it a try.
Actually... its a proximity sensor that turns the screen off... it sucks... i don't know how to word it... its boolean... so its either on... or off... no in between... I personally tried all the build.prop tweaks trying to get it working faster... no dice...

No Audio after screen replacement

Hi,
I really need your help as I have no idea what to do.
After 1 month of using MI5 Pro Ceramic black I have broke my phone,First the touch worked and there was only vertical lines on the lcd in the spot of the shatter so I could operate but due to my stupidity and of force touching the broken glass these vertical lines started to cover all the screen (Everything worked well on the phone..Sound,Camera and etc..)
So I ordered from Aliexpress LCD + Touch screen for about 70$ (Included DHL Express shipment)
When I got the screen I started to disassamble the phone.. Got everything out,Took out the broken screen and pasted the new screen on the frame (Must say all these aliexpress screens are really bad,0% protection on the screen,Not sure about the LCD quality yet but glass is horrible..Started to scratch even before I used it)
Anyways to our point..
Started to assamble back everything.. Powered on the phone and Yay! Phone is working but...
No Sound,Firstly I checked settings and everything..Ran CIT test and everything that belongs to audio giving force close..
Calibrate Speaker PA test results : State-Get impedance failed!,Speaker Vendor-None
Vibration- FAIL no short and no long
Main mic speaker Feedback,Simulation call test,Front mic speaker feedback test,Top mic speaker feedback test,
everything when I enter it giving FC with that details :
"IlegalStateException:Unable to retrieve AudioRecord pointer for SetParameters() blablala...
Headphone mic feedback test (Called on an uninitialized AudioRecord)
So in short..
No Speaker,No Mic,No headphone Mic..
Now my question is what I need to do from now.. Its not firmware/software problem for sure as before I disassambled the phone everything worked well..
My first guess was the problem is on the Sub PCB but then I asked my self..If the USB-C is working and WiFI antenna giving full signal it means the Sub PCB works so what the hell is the problem? I really hope its not something in the PCB it self as it means throw everything to garbage.. ;<
Hope to hear suggests..
I thought to order the MI5 32GB Black version take out the Main PCB put the Pro Main PCB and put also the ceramic back cover but that I would do only if I know that the problem is from the sub PCB but if Headphone mic doesnt work (Which the Main PCB take care of) then its probably in the Main PCB??
Please help!
you didnt damage the pins on the press connector? is the press connector on the ribbon cable flush / fully inserted ? Are you sure you didnt kink the ribbon cable?
I haven't pulled a mi5 apart, but can only assume its like every other phone i have.

The problem is that far as I understood of how the mi5 built and from how I saw it looks like..The Speaker located in the Sub PCB cover,Vibrate connected to subPCB,And all the SubPCB connected with the cable to the main PCB and I checked it connected good and no any damaged pins from what I was able to see..If there was damaged pins then the phone wont get charged as the USB-C wont be connected as it located in the SubPCB however it does work.. So I really have no idea what cause it..
Also the Headphone mic doesnt work in the tests..Anything related to Audio giving that FC with "AudioRecord" error..
I really must to know what causing it so I will know what to do ;<
Little update,
Just connected a bluetooth speaker,No any sound nothing..
Hi everyone! My MI5 has the same problems, no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can not play music, video offline and online video (Youtube, Facebook, live stream ..). It was happened when i replaced brooken screen. The first time when I turn on, evetything ok, I can play music through speaker, but now everything has gone..! Plz tell me how to slove this problem! Sorry for my poor E!
Hi, I ended up on buying the phone again... It's impossible to fix that problem as probably you did what I did and didn't place the motherboard correctly so a little bent probably happened and that cause to the problem.

Hi there! Care to elaborate a little more? I have also the same problem. I was replacing the rear camera module while the module I had received was broken to begin with. I hadn't really figured this out initially and I tried several times to attach it and test it, perhaps move the flex and retest, and at some I remember I found out the vibration was not there, but didn't pay attention to it as everything was open, until I found out the camera module was faulty in the end, and subsequently discovered also the whole issue with sound/vibration/key backlight etc. Instead of buying a new device, I was thinking to try and fix it, but still I'm a bit unsure about what the problem really was. From what I could figure, I didn't do anything different this particular time the audio/vibration didn't work, with respect to the previous times I attached and detached the motherboard. But is it definitely the board itself and not its flex connecting it to the sub-pcb? Could it be the sub-pcb itself or even both this and the board? In case I buy a new board (perhaps together with a sub-pcb just in case) to replace it which part should I watch out for, not to damage it again. Sorry for the many questions but you seem to be the only source of info for this specific problem.

Hi sorry for late answer,I barley visit xda these times..
After I bought the MI5 again this time in the 64gb version I tested the old 128gb motherboard (The main one) and still same problem with Vibration/Sound (While all sensors work camera too)
Which means its not the sub-pcb problem,Its the main motherboard for sure,Now what cause it?
In my opinion when I pulled of the motherboard to put it on the new screen I insert it in a bad way which made it bent a little and probably the place I bent is where the audio and all the stuff goes on..
I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

I'm pretty sure we cant really do something about that problem as problem related to motherboard it self are usually not fixable,But if you find something I will glad to get a feedback to test on my own bad motherboard so maybe I can back to the 128gb version ;| but I doubt it..

Many thanks for the response! It sheds a little light indeed. I also ordered another phone to replace it as the cost of the motherboard seems to be equal approximately close to a new device. I'm with you, in the same view, I also once placed the motherboard quickly in the chassis without the screw that holds it together, in one of the 50 or so attempts to try and make the camera sensor I was replacing, visible to the OS, and this looseness was the unfortunate one perhaps (?). I too don't expect the sound to work again. I just wanted to double check the issue was not with the sub-pcb, which I did thanks to you. For sure I have no hopes for the mainboard to work again, but still, what keeps me from being certain it is actually the sound card that is the problem, is a very similar case I saw In a foreign forum, and also clues from my device which support the argument that the mainboard might have entered in a kind of diagnostic boot state due to a hardware fault that was apparent, where either some components are not initialized during boot, or their HW resources are taken over from the diag. ports and irqs that are enabled, in which case the issue can perhaps be fixed. For sure whenever I find a good deal on a new motherboard I will replace it, to keep it as a secondary phone, as I liked it quite a bit, but It would be interesting to see if this hypothesis holds or not. Anyway thanks again for the response!
Hi,
I've bought used mi5 with broken screen. After LCD replacement I've found that that phone has problem with sound. Exactly the same as in this thread - no sound, mic, vibration, led buttons light, plugin earphones without notification's icon, can't play music, video offline and online video (Youtube).
Someone already did LCD replacement on this phone and probably done something.
But what I discovered on this phone that problem start when battery charge aprox more then 60%.
I did flash one year old ROM via fastboot ( just to verify if it not the ROM problem) and after that everything was fine ( battery level 50%).
I did hardware test - passed 100% fine.
But when I did charge till 100% the problem come back.
That's really interesting finding... Can you tell me the same steps you did like which rom you flashed and all of that? I will check it with my dead phone maybe if I will have the same thing like you we can point on something...
mi5 lcd replaced touch not working
I bought a mi5 mobile in singapore. My display was damaged. I changed many display in india (checked in many shop). only work display (lcd). Touch not respose. please some one give solution. thank you
have same problem with op
my phone get damaged by water so im rush turn it off and open everything then go to dry it... and problem with speaker etc doesnt work just like op please help i really doesnt have money to buy new phone this month
Exactly same problem with me, just replaced the rear camera and the problem occurs
No sound, no vibration, nav led not working at all, playing video not working
Even playing sound via bluetooth speaker not working too
I believe there is something wrong with the mainboard
can anyone point out which part of the mainboard responsible for the lower board?
The lower board works well though, I tested it using other mainboard

For me the problem was that after the screen replacement (It may also apply to you after you replaced the rear camera..)
When I put back he main motherboard it wasnt sat properly,I put it beneath a small plastic holder and when I closed everything and screw and all..Problem appeared and when I rechecked motherboard I found out it got bent in the right down side and that's probably what killed all the sensors,sound and everything..
Of course that what happend to me..There is plenty of other reasons that may cause to what you experience..

I believe the chip or something similar, that control the sensor, led, vibration etc, was broken because we put it the wrong way
now we need to find which chip it is and replace it
which part of the right down? near the signal cable?

If you just checked and saw you put it wrong as I did,On the little plastic which made a little bent then I guess you lost..I would just buy new motherboard on aliexpress or just give up and buy a new phone..
As you cant really know (I mean from our side..) if its a chip related there or if its the bent it self which made problem on the connection on the board it self..
And yes I was speaking about the right side near the signal cable where you need to install the motherboard from that side where there is a little plastic like holding the motherboard..When I did the reinstall by not checking I put the motherboard on that plastic and after I closed everything and all screws got back I discovered that problem..

yeah, it means it's the same mistake as mine, that little metal thing that hold the motherboard, I forgot to eject the sim card tray and when I pull my main board it was stuck, got a little bent from there
Just wonder if anyone have the schematic for mi5 mainboard, since I'm curious and want to find a way to repair it
Not because I'm in despair of needing a phone, this MI5 is my secondary phone
Just because of the curiousity, that's all
edi--
found the schematic here
https://data.dendik.id/Data/Schematic/Xiaomi/Mi5_SM.rar
now on the journey to repair this stupid mistake, lol
any help from someone who are an expert in this thing will be really appreaciated

ok bruh im already do some fking around and do ic audio replacement but no hope its still broke even my repair guy who are ex xiaomi worker are give up the problem is looks like from cpu its self but there was something interesting if u try download device info hw app in google play there was warning that the device cant read sys or something cuz it was blocked and when u look at audio chipset its was gone

Perhaps something wrong with the audio chip, will try to replace the IC tomorrow

Screen Flickering

Hey guys
I have a very strange problem with my Huawei P10
About 2 weeks ago, I noticed that two purple horizontal stripes are appearing in a 3-4sec sequence
Normally, I would immediately ask for a repair, but there's a thing which persecutes me: it only happens when I don't touch the screen for longer than 3-4sec
When there's a continuous contact with the screen (e.g when writing a message) nothing happens, everything is fine and dandy, but whenever I leave the screen for itself for 3 or more seconds (e.g when watching a movie), the stripes start to appear every few seconds, and continue until the screen goes dark or until I touch it again, but after touching it it still takes only a few seconds for the stripes to sequentially flicker again
Here's what I've tried so far (no result):
- safe mode
- factory reset
- cache partition wiping
- cord input deep clean
What may be the reason?
Hey.
It's 100% a board or Display issue. send it for repairs. but i believe maybe you've dropped ur phone. Anyways Huawei knows better.

It's quite complicated
I once dropped it, but even after that, the previous LCD worked fine, there were no errors other than broken glass, so I guess we could exclude a board issue and lean toward your second option, as now that the LCD has been replaced, the fault occurs
What's more, I noticed that if I press the Home Key, and then put my finger in the bottom right corner and hold it, I can still use the whole LCD space without the flickering (I need to press the Home Key first so that it works after I hold my finger in the corner)
It's like the LCD needs to be in contact with your finger all the time to avoid that, which has led me to an idea: would a tempered glass solve that maybe?

I can't really answer for sure but i believe if there's a Huawei service center in your city and you try to fix ur broken huawei, your wasting your time. Whatever solution u apply on ur phone its just gonna be temporary since u hide your problem and not solved it.

I still think (or should I say believe ) that there's a solution which doesn't involve another screen replacement
As for your "temporary solution" mention, I guess if I found one, it wouldn't be temporary, since the fault doesn't progress, it's been the same for a month or so when it first occured, which gives me another reason not to replace the screen and keep looking for other possibilities
I don't need a Huawei service center, I can replace the LCD myself (didn't do that the first time though), but it still involves spending money, whereas I've been looking for unpaid solutions the whole time; getting a new LCD is an extremity

You can ask them to diagnose it and tell you about problem noone makes you pay for a lcd. And after reading your message over and over (And since i repair TVs and everything with electronics inside) i think it also can be your touch or display controller ic. Mostly it could be from touch ic since screen works fine while its in touch with something. But someone has to try your lcd or mb on a healthy one to make sure. which you can't do nothing like that. or do you?
@fengels did You bought original lcd, where can I buy it in good price?
I know this problem from older galaxy series like s5. The fix for this most of the time was disable auto brightness or higher the brightness on auto brightness. Don't know if this is the same problem, but it could be a try. Also don't know which cause this strange problem. Hope it can help you

No, it's a different problem, in the galaxy series the whole screen would flicker, whereas in my P10 it's only 2 horizontal stripes appearing in a 4-5 sec sequence whenever I leave the screen untouched for longer than 5sec
Playing around with the brightness doesn't solve that unfortunately, actually no in-device settings do, as I've tried almost every single option which is screen-related, like switching the eye comfort mode on, but still no result
The main reason why I'm still looking for an unpaid solution is that apart from this one error, the phone is like brand new, everything works fine
ok, so if I understad the problem shows up after you replaced the LCD display? So do you really think is more software related than hardware? I personally would send it to diagnose and repair.

The thing is it didn't show up immediately, I had used the phone for some time with no errors before it first occured
Also, since the new LCD was set, I haven't done any physical damage to it, I've never dropped or sunk the phone
Since you guys mostly advise me to send it, I guess that's what I will have to do

While you were replacing screen, did you turn your device off and disconnect the battery? and i think cleaning all cables coming from LCD and related sockets on motherboard can help. Use thinner or alcohol and if you wanna use thinner be careful so it wouldn't touch anything except golden contacts. Thinner is dangerous and affects ur phone color and plastic parts.

I did turn the device off, but I didn't take the battery off, since it's strongly glued to the phone's body, and I didn't want to damage it
Anyway, could not taking the battery off really be the reason?
As for cleaning, I did it by simply blowing out all the potential dirt, I'm inexperienced in thinner and alcohol cleaning

I am not sure butbon some phones it damages screen. I've seen this on laptops. But anyways its done. Open ur phone and use alcohol. put 2 drops of alcohol on each socket and flat cable connectors and brush it with a soft brush. u don't want to bent any golden contact. It's last thing u can do to fix it without paying for hardware related stuff.

Well, will definitely try it then, but what alcohol? Does it need to be something specific?
