[Q] G-Sensor not working and other questions

I've just bought an used Diamond for $82. It looks great, there are only a couple very minor scratches on the display (fixable with a little Displex methinks), came with all the standard accessories plus a genuine HTC leather pouch.
Story is as follows: The owner bought it last week for $140, but noticed later that the G-sensor only works up and down. He took to "the only authorized HTC service center in Romania" and they said something about a broken foil and asked for over $150 to fix it, so he decides to sell it. He'd just picked it up from service today (the diagnosis itself cost him $5 so they didn't even give it back for free). He could've sold it for more, but lucky me.
So, i check it out, and accidentally drop it. It falls flat on its back. Okay, it isn't hurt, everything works, i pay the guy and leave with the phone. On the subway back home everything fine, but at home when i try to connect to wifi it won't start. I reboot the thing and i get the dreaded MicropError. Then the backlight decides only to work when it wants to.
I take the thing apart only to find the wireless cable had come out of its connector, and when i lift the mobo out the display cable also detaches easily. I plug the wireless back in, and notice that the display cable doesn't "click" when the board is mounted back in its place. Aha, so this must've been it. Great service center they have, they can't even click a connector in place.
I use a flat screwdriver to make sure the cable locks firmly in place, put a piece of paper under it to keep it from moving around again, and put the phone back together. Success. I haz working HTC.
It's true that a broken G-Sensor can't be fixed, right? Not that i care too much about it, i just want to know a yes/no type answer.
So, now the main question. I already noticed that the built-in speaker is crap, something typical of WinMo devices as far as i've seen. Now, the supplied headphones are also crap and it doesn't have a jack adapter either. Before i slice the handsfree and patch my Samsung in-ears onto it, i want to know if it sounds good on quality headphones. I don't need it loud as the Samsungs are plenty sensitive, but i need good bass. I have a Sony Ericsson w595 and it's got really powerful bass. I used to have a HP iPAQ rx4240, and it was loud, but it was miles behind the SE phone in sound quality and bass.
The main idea is that the HTC will replace one of my two phones - either the Nokia N93i or the SE w595. The N93i is held in one piece by superglue only and sometimes i need to restart it before it will accept a charge (and it's a PAIN opening Symbian menus for the first time after you restart it). The w595 i got as a gift this summer and is in pristine shape complete with protective foil applied to display. So i could easily sell it for what i paid for the HTC.

[Q] X1 big problem - 3.5mm- known + an unknown problem = damage

Hello people!
I still have problems with my xperia x1. I don't have money to buy another phone so I'm using it and would be ok if the case looked good (and if in my country i would find cheap parts) and it wouldn't had so many issues.
I think you didn't understand much from the title, basicly is another thread about known xperia x1 issues + 2 unknown.
So, by now
1- cracking case, scratching easy case
2- phone sometimes turn off when slide opened/closed rough. Can live with that
3. keyboard problems
4.headset problems
4.1. : all the time headphone icon showing on screen
4.2 : sound is not clear, is blured, so I have to pres on the phone in the area of the 3.5mm jack (i mean i have to press on the case in that area) or if i have the mini usb pluged in like charger and moved it back and fw i get an improvement, or by moving the headphone jack against and finding a right position, at firs I thought is form the headphone;s jack but i guess it was the connector chassis on the main board.(the headphone jack was very tight inside and stiff, so the problem wa not from the inner conectors)
4.3: together with 4.2 problem another probleam apeared. when I insert the headphones, sometimes and more and more often, the phone would start DIALING the last log from my call log (e.g. dialed/received) automaticaly. This realy pissed me off. I had to move around the headphones to avoid that, or turning off my phone network. I searched but I guess I am the onlyone with these 2 above mentioned problems (4.2 and 4.3)
So, because i bought this phone as a bargain (60 USD) as a faulty and repaired it, and had no waranty and not being scared to reopen it again, and most of my "quality" of not searching on the internet first, but trying to fix it by myself I found myself writing here a lil bit disapointed of what i did.
I opened it, tried to see wich conector is loose, then tried to put some peace of film to put pressure on the 3.5mm conector, it didn.t work.. then somehow the 4.1 problem apeared. I didn;t got this problem only once in 6 months and i solved it bak then easily with the help of my stilus. Of course I didn;t knew what was causing it. So I tried again with the stilus but this time it didn't work, and I panicked..15 minutes of pain...me trying to solve problem no. 4.2 and 4.3 and got 4.1 wich was there to stay...
started to twist the screwdriver inside rough, put pressure on the small conectors inside and outside,,and then...after pressing on the low conector i did it. It disapeared. So I was like evrika!!! I solved the problem and realisesd what was causing it. Someone else here wrote the same thing in another post, and did exactly like me, or me exactly like him
What it happens is: when headphone not inserted, the conector is touching another conector, and so this means the OFF position. When inserted - the tip og the headphone jack pushes against the conector, detaching the connection making the ON position. So when i pull of the headphones i get the ON state wich meant that there was conection (I pressed with a screwdriver and bend it there so it would alway make a conection).
BUT somehow, I didn't let it, and torn that litle piece , so know I am back again on headphones because I have no conection. So I did a conection and now it's ok but I can't use my headphones anymore + and now my 3.5 mm conector is dead.
Replace? How? Where I can find a 3.5mm chassis? It has 5 soldering conectors. I hope to replace it, and I hope that with this ocasion I will solve the 4.2 and 4.3 problem
Any clues on getting this part? Or a compatible one? Or a better one?
LE: so if you encounter problem 4.1 just insert the stilus in there and move it at the end of the hole or take a cotton bud and clean it with some alcohool, it might be dirty.

no more x1 users here?

my X1 have hard-keyboard, scratching problems.
I'm using it more than a year but never had 3.5mm jack problems.
before giving some serious damages you should give your device to HTC or SE repair service.

[Q] Commons problems of hardware on Milestone/Droid phones

Hi, greetings from Colombia!
Mi Motorola Milestone (that I buy the last September after my lost Nokia 5800) on this days had one hardware problem, the power button failed (semms broken), so I take it to the warranty (using CyanogenMod 7 for Milestone Android 2.3.5) and the fixed it!! Weee... But...
I just enjoy my fixed phone for just 1 week, because another defect comes up, the digitizer begins to fail, first, become unresponsive from the right side (and the search button), and, after 3 days, all was OK, but in the afternoon the scren become "crazy", and sometimes the right side begins to fail again, so.. this Monday i has to return it to warranty (I'm hoping that they change my phone for a new one).
From my sight, I have a really bad luck, having two of the most commons problems of this Milestone/Droid phones.
Do you know another common failure of this phones?

The "bubbly" keyboard is quite likely to lose a few keys and the paint on the camera button comes off quite frequently.

I have experienced some of those hardwares problems with 2 Milestones. The camera button I guess its the most common.
Hardware problems that I had:
- Digitizer failing. Replaced on warranty, no problems since.
- Camera button paint came off.
- Bad headphone jack.
- Bubbly keyboard on one of the phones, went to RMA, problem persisted.
- Loose battery cover.
Most of the problems you can live with, except for the failing digitizer.
Sent from my Milestone using XDA Premium App

my digitizer went bad. bought a replacement on ebay. arrived in 9 days. it ain't so straightforward inside the milestone coz of the slider mech but all's good now

Second that.
Lots of people report their screens going nuts or becoming unresponsive - due to moisture or general digitizer failure
My headphone jack was a pain at first - but the more often I use it the better it gets

Guys - I am expecting to receive my Milestone (1) on Monday. But I am just now seeing these hardware issues that you had. After how long did the hardware problems - especially the digitizer - show up? I'm wondering how long I will have to go before it starts calling for parts!

My digitizer died after 9 months (December -> August). At the beginning (first week before completely dead) right side of screen stops working. In second week I saw that digitizer is jumping over menus by itself, then screen stops working.
Everything else is working fine. I hope there will be no other problems with other parts of phone

Same time for me, after 9/10 months my digitalizer started to fail, and the power button problem was 9 months after I got it, btw maybe my power buttons problems was caused by using this buttons to hang out calls (using CM7 settings), so my advice, don't use this function.
And, talking about my phone, the replace it . Now I have a new Milestone, wee...

I bought mine in May 2010 and haven't had any hardware problems.
But a friend of mine bought his' just a month earlier and his keyboard fell apart and the camera button lost its coating.
I guess it's just a matter of luck - and good care of course

The headphone jack has been the only problem I've run into, and it's an issue that apparently can be at least partially fixed by shimming it in one direction or another.

Thanks for the heads up. It seems I have nine months before sh!t starts happening then! Lol. I'm wondering if some of those hardware problems can be fixed or prevented by opening up the phone and giving it a periodic brush out / clean out? For example the headphone jack after becoming loose can probably be re-soldered, etc?

I don't think the solder connections are faulty on the headphone jack.
It just seems to be a little to loose for most 3,5mm plugs.
Some of my headphones give me a lot of trouble - others none at all.
And the more I use it - the less problems I get.
So I'm led to believe that it's more a problem of dust and corrosion that worsens the contact quality.

Talking about headphones, I use a wired BlackBerry headphones, seems ok for me, but sometimes when I move it in the jack, my music is paused (maybe this is related with the different standars of jacks?)

Even if you use a standard 3,5mm stereo connector with not 4th contact at all the phone's gonna interpret a slight loss of contact the same way it does pressing the media button on a media headset.
My Milestone sometimes started playing music when I was watching a movie or whatever.
But if your Phone is rootet you can use the app Autostarts to disable the phone reacting to the media button and therefore problems with loose contacts.

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..

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

P30 Pro Failed Lower Microphone Issue - Workaround possible?

I really like my P30 Pro but this last week callers have been complaining they can't hear me all of the call. It seems to be this happens for the first 10-15 seconds of the call and then sporadically throughout the call. I have searched the internet and found that the bottom microphone is not working. The reason that sometimes the caller can hear me is that there is an upper microphone which kicks in sometimes. One solution is to use the loudspeaker option - which appears to use the upper microphone all of the time. Apparently using WhatsApp for calls works too. I was wondering if there is a phone caller app which would utilise the upper microphone all of the time (unlike the default Huawei one). I suspect not, but I think it was worth asking. I have read of people having the same issue and replacing the lower microphone/SIM card unit but it still not working. One person who replaced the microphone (which still didn't work) suggested it might be "the analog to digital converter of the microphone signal" which could be at fault.
EDIT : Just to say the phone is still under warranty but I have a quite badly cracked back on the phone (front is fine) so I guess that may invalidate the warranty. The back has been cracked for quite some time though and the microphone issue is only recent

Same happened to me, changed the sim/mic board and its working again

Thanks.. I bought a SIm/Mic board and a USB ribbon/connector. I couldn't fit the sim/Mic board as I couldn't get the connector from the phone onto it so put the old one back (the board wasn't OEM and I don't think the quality was there). I replaced the USB ribbon/connector and the microphone worked. However, the USB connection wasn't great and fast charging only worked with the USB the one way around. I replaced it with a refurbed original ribbon and all is fine. I wonder if just refixing the SIM board and USB cable would have sorted the microphone too a) why would me replacing one part and you replacing a different part sort the same issue? b) I have seen a post from someone who sorted it by applying pressure around the edges of the phone and the SIM area.

I've also started getting this problem. The other party can't hear me on phone calls for the first ten seconds, and when they finally hear me it's very poor quality. Google hotword recognition also isn't working. I'd only seen people saying they'd replaced the sim/mic board and it hadn't helped, but perhaps they didn't change the connector? Good shout, I'm going to try a refurbed cable.

Having issues with the lower microphone that's been listed all over the net, ie delay in hearing me when answering calls and google assistant not hearing me.
Two lower sim/memory/microphone boards later still didn't fix it. For me swapping out the USB ribbon connector has cured it. Just in case this helps someone.

Hi, I replaced the small board as shown twice, but it was the usb lead also shown that ended up fixing it. I'd start with that. Good luck

Hi! I've got the same issue for some time ago... just purchased a new microphone PCB and replaced with no success. Diagnostics on the phone launched a NON WORKING message
Then just surfing the internet I found this forum where I'll share results once I replace the USB charging (and more) flex.
Cross fingers!!

UPDATE!!
** PROBLEM SOVED**
After replacing the charging flex, the microphone is working FINE .
Selfdoagnostics PASSED succesfully for the microphone testing.
▶ I can not realise about what's the hardward problem but it's true it works.
These are cheap pieces, and taking into account I'm in love with this LAST-Google Serviced Huawei P30 Pro... I really believe it will last at least 2 or 3 years more in my hands!!

Glad you found a solution. I warrantied my phone 9months ago because of the microphone issue. Now it is malfunctioning again unfortunately. The p30 pro has everything i need, still full day of battery. Out of warranty now and prepared to try to repair it by myself. Trying to find how thick tesa tape i need to put it back together, which tape did you use? Do i need Best B7000 glue aswell? Havent taken a phone apart the last couple of years so I need som basic guidance regarding glue and tape.
Best regards
