. . . and I have to hit the power button to turn the screen back on. To be more precise, the screen turns itself off when I hold the phone towards my ear during calls, and it does not turn itself back on when I hold it away from my ear.
This is obviously some power saving feature that doesn't work as well as it should, like a gimpy proximity sensor. Anyone know a workaround for this ?

Well, ther is a proximity sensor there, near the camera on the top of the phone, on the screen side, and this screen-off thing is more like feature to save power and not to anoy you during the night when you talk to the phone
Don't know why it does that, maybe your sensor is faulty, but try to flash a different ROM and see if something changes, also make sure you don't keep your hand or finger near that sensor, just to be sure, i personally use this ROM and i don't expierience this issue.
Hope this helps

I actually have this EXACT same issue and it is really annoying me.. I have a feeling it is the senor that is faulty, because I haven't even rooted my phone yet.. so everything is all on stock....

If it is possible on Galaxy S2, then it is possible on any android phone , and it is, but there should be made a tool for that or a flashable zip, i'm not that experienced to tell you exactly what needs to be changed, but it can be done, that i know
Same problem here.
Changing roms didn't solve anything
Anybody have solution for this ?
If you have a screen protector covering it then it might be wise to make a cut out or take the protector off altogether.
Sent from my Nexus 4 using xda app-developers app
as i remeber , you can write something in the build.prop that will disable proxy sensor
Im having problem that is almost same. After a long call(when screen is turned off) it turns off but screen or softkeys dont reply any way.
I have to turn of the screen with power button and let it be around 10-15 seconds and turn it on. Then lockscreen appears and everything
works. This is really annoying because I cant cut the line any way.
Not using screen protector and tried couple of custom roms. Allways have the same issue.

No I don't have screen protector or cover.
Problem is identified with proximity sensor itself, on App " Android sensor box " if you select proximity sensor it reads always 0.0cm no mater what you do with phone.
It seems like HW failure, will have to look at it in more detail.

The problem is when you try to make a second call display turns off, phone is working you can talk, but you can't end the call or nothing because screen is off, so you have to turn it on or wake it by pressing power button.And it's happening only on every second call, so I make a first call, as soon as I try to make a second display turns off, and only power button wakes it, after that you can make the next call normaly, but problem repeats on second call.
Phone was stock on ICS 4.0.3, and making problems there. So it's now fully unlocked ( S-off ) Hboot is 1.28. I have tryed many custom roms, but the problem repeats
I think it's the hardware problem with proximity sensor.

I think too. Sounds like your proximity sensor is weird.

To continue the story, I removed the MB and when the proximity sensor is out of the case, it works ok. When I put it back in case( behind screen ) it doesn't respond again.
Cleaning didn't help, will have to find another one to make sure what is the problem.
I have fixed my problem thanks to this thread

This started happening about two weeks ago. During a call when I pulled the phone away from my face in order to press the end call button, the screen did to wake up. I could not end the call. This has been happening quite regularly now. The screen simply does not turn on after or during a call. Even if the other person ends the call from his side, the screen on my phone does not start.
I was using the stable version of the official CM7 at that time so I flashed the rom again. Since that did not work, I did a clean installation of Mebitek's CM7 without restoring any backups. But I am still having the problem. I am now using the power button to end the call like a handicap person would.
I think something might be wrong with the proximity sensor or my battery. Since, I have absolutely no expertise of how the phone functions, I seek help from you guys. Please give me some suggestions.
try changing the proximity delay
Flash new rom.

I used to have this same problem. The problem seems to be a combination of the screen protector/case getting in the way of the ambient light sensor and therefore not allowing the phone to accurately measure ambient light, and the phone going into some sort of sleep mode. I usually wipe my ambient light sensor off, and adjust my silicone case to allow the light to come in, but the thing that solved the problem for me permenantly was running the small app called wakelock to keep the system from going into complete standby. I am sure that this solution affects battery life, but I still get 10-12 hours between charges which is enough for me.
This thread talks about a similar problem, and this is where I got the idea to try this fix for our problem: http://forum.xda-developers.com/showthread.php?t=1491223

No no no guys.. don't bother with reflashing and stuff, that's not the problem.. I had the same problem and I googled it for months until I've learned its a Samsung wifi hardware related problem and mostly Galaxy devices are affected. Something is wrong when phone goes in standby. It continues to work but you can't wake it and you have to reinsert battery to get it on again.
The solution is to install a tiny app called Wake Lock, it's there on market.. it keeps phone awake even when you lock screen. My phone doesn't shut off anymore and I can finally rely on it. I don't have to think anymore and check all the time if the phone is off and if I'm going to miss a call...
The alternative is to turn off wifi before you lock screen but I think that most of us need wifi on all the time to get mails and messages on time

I am of course mistaken. It is the proximity sensor that is malfunctioning due to the screen protector and case.

Where to locate that setting?
Hey guys so I'm having the following problem, during a call when I put the phone near my ear and the screen turns off, sometimes the phone stucks, what I mean is the after I remove the phone from my ear the screen remains turned Off and the buttons do not respond.. But the call is still working.. I had gueste rom then I changed to cyanogen but the problem is still there...
Unresponsive phone perhaps, because as far as I know, nothing of the sort happened to me ever.
Also, does the screen light up when you end the call...let's say by using power button?
Not likely, but I'll mention anyway, check if anything is blocking the proximity censor - holding habit, cellphone case etc.
Similar issue,any way to disable the proximity senzor?

I have pretty much the same problem,the screen remain turned off after i remove the phone from my ear and i can't activate the screen or press any buttons until the other person terminates the call.
I run a proximity test from the Hidden Menu and the sensor detects as NEAR all the time even though nothing is in front of it.
I reinstalled several roms and i still encounter the same issue therefore it must be a hardware problem.
I would like to specify that i don't use a screen protector therefore the senor is not blocked in any way.
Is there any way to disable the proximity sensor completely?is there a application or a setting for that?

I have had the same problem, with many roms. I think if you are on some of the ICS roms, you will have to expect some bugs, like this. I am now on Temaseks build 135.1 with his kernel and I dont have any of these bugs. It seems ICS for our P990 is to be expected soon, so try a ROM as close to stock as possible and wait for our ingenious developers to get the last drivers working and you will see a lot of bugs disappearing. I would not recommend you to disable additional hard/software.
One app that has helped me though, with some of the ICS issues, is AnTuTu CPUMaster. A free app in Play and it allows you to set your minimum clockspeed a little higher than standard, I set mine around 400Mhz and it took care of many of the little bugs related to phone not reacting according to expectations.
Good Luck
Have the same problem and man... its a huge pain...
I am on the official CM7 latest release. I used to be on temasek's one and did not encounter the problem. As I can;t change ROMs these days, any quick fix, calibration app that would do the trick? Thanks!
I recently replaced my screen and ever since the screen would go black during calls,
I figured that the sensor has
2 parts, sender and reciever
If the receiver can see the emitting light from the sender then there's usually something for the sender to bounce off, when the screen was replaced there's something different, there's nothing inbetween the sender and the reciever! So the screen is reflecting the sender back to the receiver,
Step 1 disassemble
Step 2 remove LCD board,
Step 3 detatch proximity sensor from board
Step 4 cut small line of plastic from New screen inside the viewport ( where the sensor can see through) it should be touching the glass separating the 2 sensors but its not, hence why the sensor activates thinking something is infront of it but its reflecting throug past the piece of plastic.
Cut it out carefully with a razor.
Step5. Use double sided foam or anything else that would work to block and sit inbetween the 2 parts of the sensor and the screen, I used double sided foam and stuck it to the proximity sensor rubber,2 layers.
Aslong as you seperate the 2 sensors completely it should now work again.
I will be adding pics soon
Thank you very much
It helped me to fix my problem.
Thanks. Just repaired proximity sensor using your advice!

Here is the solution for your request. I have requested the developer to include the option in his app for our jelly bean ROMs. I have noticed every Jelly Bean ROM has the same issue. So you download this app https://play.google.com/store/apps/details?id=novum.inceptum.proximity&hl=ru go to Smart Screen On/Off then activate it and tick Only during call option and it will solve the problem.

Sorry this is the right app it is called Proximity Actions from Google Play (the developer developed for us by my request to solve the problem with black screen during call in our ROMs). I have corrected url above as well.
https://play.google.com/store/apps/details?id=novum.inceptum.proximity&hl=ru Go to the app first of all put mark on Start/Stop Service in order the app to work. Then under section called Actions there is the last section called Start Screen On/Off. When you open "Smart Screen On/Off" activate it with marking it. Then you go to the last section called "Only during call" activate only during phone call. And push the button "thank you" for me in here. Also go Play store and thank the developer as well. He solved our issue.

Couldnt even connect to the pc. Then i flashed linora..it is a pretty good rom. Can live with it and pretry fast than sense ui roms. most importantly fixed my proximity sensor 100%. But still my touchscreen freezes sometomes. I have to lock and unlock the screen to bypass that. That's my next headache.

When I am in a call, putting the phone to my face turns the screen off using the proximity sensor. However, removing the phone from my face does not turn the screen back on. Nothing turns it back on even if I push all the buttons or hold them or do anything unless the other person hangs up. I cannot remember when it started....before or after the recent update.....but it did start very recently. Any ideas? If I turn off the proximity sensor during calls it works fine by locking and unlocking the screen with the buttons.

Is anything covering the front facing camera, or light sensor? Like a case, bad screen protector, etc....
Does your front facing camera work just fine as a camera?
How about air gestures? Do they work?
I'm asking these things because it seems your proximity sensors aren't working properly. Your phone thinks it's next to your head all the time, so it's not waking the screen until the other person ends call. We need to find out which one is acting up and why.
The front camera works, but in my office it seems VERY sensitive to light. The lights are glaring heavily. I never use the front camera so I don't know if that's normally how it was. Air gestures work when the screen is on (swiping left and right to view my photos), but the quick glance won't work when the phone is locked. The weird thing is that quick glance works when I do the "try it" tutorial only.

Unfortunately this sounds like a bad proximity sensor. This can be verified by testing the sensor by dialing *#0*#
I had this happen to my last Note 3. The only difference was I could turn the screen back on with the home button.

I tried that *#0*# test and I can activate the proximity sensor, but it seems to stay on after that.
This is a known issue with our phone. I had this issue myself. Plenty of times. Just call ATT and ask for a replacement.
Yeah I just found this:

i stumbled upon this thread and took my phone apart and sure enough there was lint in it. in the dial pad using the *#0*# method, when i covered the sensor the screen would light green, vibrate, and stay that way after i moved my hand away. i cleaned it and everything is perfect!!!

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?
