Hello. I've had this device for awhile now and it's probably the best phone I've ever had.. except I started to have problems with regards to calls just recently. I actually rooted the device about 2 months ago and am currently using the Rombie mod v2 (JPC), if that helps. Anyway, the problem happens in the middle of a conversation, where the proximity sensor somehow disappears and the speaker mode is activated on its own (or maybe it gets in contact to my skin, I'm not sure, since the screen is supposed to remain blank). After that, the device becomes unresponsive: the touch sensitive menu and back keys don't work, and neither does the screen itself..but the hard key home button works and I could still hear the other caller via loudspeaker. I force a reset and everything goes back to normal (I mean this call issue doesn't happen all the time). I don't have any screen protector to affect the performance of the sensor. Anyone can help me out with this? Thanks!
Hello,
My Touch screen doesn't respond to touching since an hour ago.
I see no logical reason for this fault,
My screen is guarded and nothing happend to it.
I tried to remove battery and insert it with no luck, I booted my phone into CWM touch recovery, and it also doesn't recognize touching.
update2:
The problem appeared again.

The problem appeared again I tried a lot of times to remove battery&insert but it doesn't help.
Please help me.
I've just flashed my phone to stock rom,
I'm still having the same touchscreen issues - the screen won't respond to touching.
Any suggestion please?
Is it possible that the touchscreen issue is caused because of the screen protector?

Screen protector protects screen If you have got stock FW back on the phone, just bring it to your carrier and they should do it on warranty.

Thanks for the advice,
I flashed stock rom and now when I turn on my phone It shows me the "Android Welcome Screen", Is there a method how to bypass this screen without touching the screen? (If I'm taking phone to my carrier, it might seem strange to them that my phone shows the "Welcome screen" whether the touchscreen doesn't work so they could know I flash my phone and not to accept my phone's warranty)

You can try on-screen phone, which is a software by LG, but i think, that this also needs to be setup first... Otherwise, just tell them, that you did a factory reset, because your phone wasnt working properly anymore, and thats when your error occured.
I dont see another way... Maybe repair it on your own

I'm going to take my phone back to carrier
But there's very strange thing: the touchscreen rarely works.
I removed the battery for a night and when I got up in the morning and I inserted the battery and turned the device on, for a few seconds the touch worked . What does it tell about phone?
I've just received my phone from repairing, and my touch screen has been replaced.
I'm a little disappointed because I expected for getting new phone(I have a warranty). I've also noticed that the screen is a little thicker, about few mm, which is weird.
Is it right that phone with replacement touch screen won't be as smooth and good as normal one, or not necessarily?
Same problem of Freezing screen
Disappointing but i too have this very same problem with my brother's P970... any ideas how or why?
though sometimes it would respond but leaving it a few minutes would again make it freeze. The hardware buttons work but the 4 touch buttons wont. now i cannot get thru the rom manager to make it into Bootloader mode so i can install another rom...
some things i did a few days before this happened:
1. flashed CWM recovery successfully.
2. installed a lot of apps and happened to fill up the SD card.
3. installed a new ROM Gingerbread Repackaged V20N
I can still get to S/W Upgrade but all I need is the Bootloader Mode. I honestly dont think this would be a digitizer malfunction since it works well in a given time. It's like it lagggggs much and unresponsive. I cannot get past the lock screen. Any ideas or any other way to get to the B/L mode? Thanks.

ARZAKEM i have the very same problem too i was also doing the same stuff which you atempted and end up with none responsive touchscreen.
my phone is since then lives in a my draft in the kitchen and i was also curious about the malfunctionality because it worked sometimes and other times not.
I just thumbled upon the post when i search the web i know its too late to ask but could you please please tell me what you done with that phone ???
I ordered a new touchscreen from ebay and it will arrive soon but i was wondering wether you managed to fix it or not? could you please tell me what was the real problem did you replace the touchscreen or is it not the touchscreen?

You need to indicate your current ROM. Then can the issue be accessed

I haven't seen this posted anywhere so I figured I would post for anyone having a similar issue with their One.
Recently my phones backlight stopped working. It would not work at boot or in the ROM. I tried flashing to stock and tried optimizing the proximity sensor, but no luck. It was clearly a hardware problem.
Not seeing any solution to this issue other than people saying it is the screen or the motherboard I decided to order a new screen.
Well installed the new screen, still no backlight. I was about to give up on it and just buy another phone, but I got the feeling that the light sensor may still be my issue. The backlight on the capacitive buttons would not turn on unless I helded down the power button to force shutdown. This meant the backlights for the buttons at least worked and something else in the phone was preventing them from turning on.
I decided to remove the light sensor from the daughterboard (opposite the power button connector). Booted it back up, and the screen came right on. The phone works great without it, other than auto brightness. The screen still turns off when against face during calls.
So long story short if your LCD and button backlights aren't working don't order an LCD or rule your phone dead right away. Open it up and take out the light sensor, it could be the culprit.
I'm going to order a new sensor and can update with results after installing if anyone is interested. In the meantime I'm using the phone without it, no hiccups so far.

hey
i'm having the same problem are you sure that it is a hardware issue and not the software issue my h/w buttons doesn't light at all and my screen stays black for some time after unlocking the phone it comes back but the brightness is too low
any suggestions would be appriciated
Mine was a hardware issue, the backlight did not turn on at all, even on the htc start screen. The capacitive buttons would only flash when holding down the power button. If ypurs is intermittent and your phone is rooted you cantry insralling an app fhat alows you to change the proximity settings, sorry, cant remember the name of the app i tried. If the app can't detect the sensor it is likely broken like mine was. If that doesnt work try a different rom.
If neither of those help it is likely a hardware issue.
i used the app both light senor and proximity sensor are working fine
any other tips that i can try

Sorry for taking so long to respond, just noticed your reply.
Did you ever get it working? If a different rom did not solve your issue maybe your sensor is just dirty. You could try cleaning it with a can of compressed air. Not sure how effective it would be, but it may help.
Hi @nsodmordex, my HTC One M7 is in the same situation as you describe, no backlight, but working. I'm going to try your suggestion of removing the light sensor, but I'm unable to find it, I'm not sure where the light sensor is.
Please, can you tell me which component is the light sensor? This is a photo of the daughter board:
htt ps://d3nevzfk7ii3be.cloudfront.net/igi/ALPJIMWqGsLwul5Y.huge
Thanks!
Found it... it's located behind the daughter board, at the two little holes of the front cover of the phone. I have removed it but no luck, the screen continues black, but the mobile is working good.
it seems a screen related problem, I'm going to try to change the screen and see if it comes to life again.
Drain battery
Hi all,
I also have this problem and found out that if I drain the battery completely and wait about 1 hour, it turns back on when I put the charger in the phone, if the screen doesn't turn on, drain and wait longer, if it does turn back on then power the phone. Do not wait till it has a little bit power because than it fails again and you must drain and wait again.
It works for me and I will make a video of it and post a link later.
Hope it works for you all!
Tip: use a led flashlight to see what's on the display
Ps. Stock m7

Than the lightsensor is broken, are the contacts on the back of the sensor 100% clean, in my case it was dust that created the error.
Is the display not broken?

The display is ok because I can see what is on the phone with the LED flash of a Galaxy S2 so I think that the display is not broken.
The backlight doesn´t turn on with the light sensor and without it either. But i can remember that the last time that it worked the Autobrightness was fine
Edit: I tried rebooting on fastboot and recovery via ADB and the screen is without backlight too
PD: Sorry for my English

In my case, if it worked it was ok also the autobrightness.
I think the sensor is broken and if you replace it the backlight comes back on (sensor is +- 10€ in holland)
Just give it shot
Have you tried the battery drain?
Hehe my english is also not very good

But as I read, if I remove the sensor and turn on the phone without it, will it work?
In this moment the phone has 0% battery and if I plug the charger i can see the red light and if i use a flashlight, i can see "the battery with the lightning" on the screen

No i dont think thats gonna work, push the power button (whitout charger) every time till the battery is really empty, than wait an hour.
If you connect the charger and the screen will not turn on, wait longer. a night is even better.
If the screens comes on then turn direct the phone on dont let it dim itself or else you can wait again.
This worked in my case but my lightsensor was dirty and after a cleanup it worked normal and it stil works.

Okay, thanks, it worked once, but with the phone turned on and the backlight working, if the screen turns off, the backlight runs away again.
can you repeat point by point what i need to do?
when you say "drain" the battery, you mean leaving the phone on till it turns off? then what should i do? wait an hour and plug the charger to see if it works right? okay, and later if the phone turns on what i need to do?

By 'drain the battery' i mean continuously turning the phone on with a empty battery till it does nothing, not even vibrate.
It must be so empty that the phone not knows its a phone.
And yes if the screen comes on just power it on, thats it.
1 drain
2 wait
3 plug in charger
4 screen comes on
5 turn phone on
6 done
1 drain
2 wait
3 plug in charger
4 screen stays off
5 drain and wait longer
that are the steps that worked for me
Thanks @Dippie83 , it "worked" draining the battery and waiting forma a night to turn it on but when i turn on and i push the power button yo lock the screen, the backlight stops working
Any idea?
Hi, my screen broke recently and i can't use the tactil touch. I can see the image but can't use. So i decided to buy a LCD + Tactil Touch + Frame. I didn't mount yet the screen. I only disconneted the screen flex and connected the flex of the new screen. But the problem is that is black. The screen seems to turn on but i don't see anything, is all black.
EDIT: I don't know where to ask. I flashed to the stock ROM, 4.2.2 and still black. I updated to the last version Sony has for my phone, 5.1.1 and still is black. I don't know what more to do. Is all working good, even the sounds when i touch the screen. But i can't see anything the screen is working but there's no image. My phone is Xperia Z.
Anyone?
Please help!
Broken screen? Is the old one still working? If yes: return the new and broken display and get a replacement!
The touch("screen") and feedback (vibrate and sound) will work without the lcd! It is a different layer on the screen and is seperatly connected to the mainboard of the cellphone. Also your screen could be working and your backlight not! Turn on the phone and point a bright flashlight on the screen, maybe you will see something, but even then, get a replacement.
