[Q] viper one screen failing while charging - One (M8) Q&A, Help & Troubleshooting

First of all thanks for such awesome work on this Rom. I am facing a weird issue and I didn't find anything in the thread...
When I am charging the phone basically the screen stop responding, if I touch an area on the screen, the response is like if I touched somewhere else and even the browser starts by itself.
Have anyone faced this issue? Could it be a firmware problem? I'm s-off and I have flashed the firmware myself.
Cheers.

more info
Hi all,
Just a bit more information on this issue. I have noticed that the screen start behaving weird only when I'm using the HTC dot case. If I use the phone without the case while charging everything is just fine.
Is anybody able to help on this? Maybe the magnet sensor is having a conflict while charging?
Thanks a lot.

[Q] Black screen on HTC Desire

Hi guys
i have a strange issue on my device,since stock ROM i guess, the problem is follows:
my screen just go black sometimes i thing it happend only when a call is in progress or when call is ended by the third part, the screen just stay black and no solution but uplug battery and start up the phone
i had this problem eaven on my stock Rom froyo 2.2, then i try leedroid 2.3 and it was ok i guess, then i try oxygen rc6 everything works superb,fast,clean,smooth but the black screen occures multiple times in one day (today around 3 times) so i was forced to return to my stock froyo 2.2 and hopes will be ok,
the problem is as i search thru internet... seems like one of the sensors works baddly, i think is the proximity sensor, what can i do? should i sent my device to repair? i realy appriciate any help and suggestions and ideas how can fix this problem....
still no solution it happens on stock froyo 2.2 too but in smaller period as on oxygen rc6, i try set --- display off to value 30 minute from previously 2 minutes and problem dont occured for last 2 days
this might seem like an ovbious answer but when your making a call the desire has a light/proximity sensor to the left of the top htc logo that turns the screen black when it senses something, this is to stop you pushing buttons with your ear.
i dont mean to insult your intelligence or anything, just saying ya know if it happens when not in a call it sounds like a software issue
i already know that, searchin a lot about this problem mate trust me, i also know when the proximity sensor is located and what is his function but the issue happening only when a call is made never happend just like that so i thing no sw prob, using stock froyo 2.2 now no root just a clean official and it happens like 2 times per day when i was calling more that 2 minutes when i set in setting--display to turn off screen in 10 minutes this problem dont show up soo i dont know realy maybe i sent my device to reklamation will see
This happens me with root and without root. It's when your using anything that has with the SD card to do with. Like the gallery, it has gone black for me to under a call though... I dont know how to fix this problem, and it's very frustrating to take out the battery all the time.
My friend i am working in mobiles but i couldn't guess the problem cause i bought my cousin this HTC desire until she removed the screen guard (( the plastic sticker for protect the screen)) from the screen and i solved the problem so easily.
Best of luck
true is that i am using Zagg shield, but this cannot solve the problem cuz i try few days without any screen protector and the problem was still there,
but i guess i solve this problem few months ago, i notice that the black screen after call happend when my network is set to "GSM only" strange but since i use WCDMA only the problem is gone, dont know surely but guessing, also when i use mobile network in gsm only mod, phone freezes totaly and only unplug battery helps, as i said since i am using wcdma/hsdpa/3g only non of these strange thing happens
hope this help for someone

Thanks
Hi all,
This was happen to me last few day and i google whole world, finally i find my answer and i hope it was help for those who facing this kind of problem.
I can confirm this problem no related to rooted or without rooted phone. this problem definitely come from the proximity sensor which people highlighted this sensor located at top left of htc logo which u can see a blue color circle there.
Try watch this video of disassemble htc desire and you will find the way to clean this proximity sensor area.
Tools to use for dis-assembly:
1. Philips screw driver.
2. Torx screw driver
Cleaning tools:
1. a wet small cotton buds.
Hope this method can help.
Area to clean:
1. The proximity sensor which you will see covered by a black rubber
2. The casing area which i show on photo.

[Q] Touchscreen stops working

Hi,
sometimes the touchscreen of my defy stops working (but the phone is not frozen)
and the only way to fix it is to lock/unlock the screen...
does anyone have the same problem (and can help me)?
thanks
P.S
i've had the problem both with stock rom (2.2) and with cyanogenmod rc 1.5
When this happens, do the 4 buttons below your display still give you haptic feedback (little vibration) or do they react not at all?
Also, does this only happen when there's the normal launcher/standby screen active or when there's an other app active too ?
Did you undervolt ?
Edit: Also, this seems to be a hardware problem which seems to be well known in a certain German android forum but I cannot find much about it in here. In short, the digitizer unit seems to be broken for some people and locking/unlocking helps because it disconnects and connects power for the digitizer. The people there fixed the problem by replacing the digitizer (which isn't easy at all!).
It would be nice to have someone from XDA who had this problem before too, to confirm this problem!
First of all, thank you for the answer
When I have the problem, 4 buttons stop working too.
It usually happens after a period of stand-by, i don't undervolt or have some other application running than the launcher (ADWlauncher).
I bought the phone one week ago, if it is an HW problem, i can't repair it by myself...
I'd recommend to wait and see whether xda has other suggestions for you and if not, just check the Motorola hotline and ask whether they know something and if they do change it for free.
Also, what you describe fits perfectly to what I've read elsewhere (don't know whether I'm allowed to post a link here or if it were useful at all because it is in German). So it sounds like your digitizer could really be defect.
ok, even if i hope to solve the problem by myself...
News: They've changed the touch screen, but the problem is still present...
Can it be a sw problem??
Keep sending it back, they will replace it in the end.

the whole phone?
Yes, the whole phone. They have two year warranties, but don't put up or make do, you should have a phone that works right

I use to get that problem on stock and some versions of CM.
Was definitely a software problem for me, havent had that problem since I'm on nightlies.
I wonder when it happens ,are you charging?

[Q] 2 questions

Hello,
Recently i opened my HOX to change the battery to a HOX+ one. I succesfully did that, but i think i lost a connection or possibly damaged something that connects my G-Sensor. Does anybody know something about this?
Second question:
Since i installed Sense 5.0, i have this weird lag with the statusbar. It drags down like 5 seconds after i made the swype. It also stays on half of the screen often. Does anybody know how to fix this??
Greetings,
Happiness
Well as for your g sensor it is a common problem I've heard a lot these days..due to updating to sense 5
Your other problem I don't know how to fix..you can try a full wipe and reflash the rom

Top section of the screen not working

All of a sudden after charging my phone the top part of the screen is not working. Has anyone else experienced this problem and is there a work around. Please help cz it's really annoying
it seems to be an issue with the digitizer i had the same problem i had to replace the whole screen and you can use the line drawing test in the hardware diagnostics section under the htc guide app

[PROBLEM] - Fingerprint sensor not working

Hi guys, I'm currently on AEX 4.6, everything is running smoothly but all of the sudden my fingerprints sensor is not working as well as the slide options. The actual button works. It clicks so I'm managing to use the phone normally but no u-touch function. I've already tried different roms and nothing seems to work. Has anyone experienced a similar problem? I'm afraid it's a hardware problem.
I'm glad to say that I found the solution for this problem on another thread. The sensor driver might have had an issue, so installing it again will solve the malfunction. After all it wasn't a real hardware problem. Just download the file I'm sending and restart your phone so it'll come back to life again :laugh:
Here's the link:

PS: it didn't work at first with me. So I sort of gave up then I tried another time and it worked.
