My screen turns off during call, and can't turn it on during call - Galaxy S III Q&A, Help & Troubleshooting

I have this issue with my S3, that is infuriating! Whenever I get a call and answer it, my screen turns off after a short while and during the call I can't turn it back on. The power and home buttons do nothing, and the proximity sensor isn't working either, so I can't turn off a call.
Anyone know how I can fix this? I have Lollipop, CyanogenMod 12.1 custom ROM installed.
Thank you for your time.

This bug partially exists in stock roms too. It's just magnified in custom roms.
You should be able to set it to keep the screen on during calls. It's the only way i know of.

I fixed this problem by opening up the phone, unplugging the proximity sensor, and throwing it in the bin. (the trash to you Americans)
Screen stays on during calls now, but I've not had problems with accidentally ending calls with my face, so I'm happy.
You also lose your front camera because it's part of the same tiny PCB. But I've never used the front camera on a phone in my life. So my solution is perfect for me, but maybe not for you.
The other option is a software fix. There's an app, or a method that you can do yourself to disable the proximity sensor, but I had problems with it, so did it my way.
Edit: I forgot to mention that the reason my proximity sensor wasn't working was because whoever had this phone before me did a screen repair and had half severed the ribbon cable for the proximity sensor by accident. Not just because of the bug that sometimes exists.

Proximity sensor problem. Manually calibrating it solved the issue for me.

Go to that thread and follow instructions. The code for sensors might be different for s3, Google it.

Bah, that's the boring way to fix it.
(didn't work for me. maybe work for OP though)

I remember that I saw a MOD or xposed module to keep screen on during call.
It's better than throwing the sensor to the bin (trash ) .

[Q] Proximity Sensor Issues?

Am I the only one having problems with the Proximity Sensor on the Atrix? I can't seem to get it to kick in when on a call. I have already dial-toned a couple of people when talking on the phone. I have tried covering up the sensor by placing the palm of my hand over the to 1/2 of the phone and it never kicks in.
Can someone verify for me that it does work and not some software bug.
Thanks,
Ed
Did you ever find the problem? My proximity sensor has stopped working also.
i am having an issue with mine too. at first i thought it was an issue with the screen not coming back on, but now i realize that the proximity sensor is not turning off the screen at all and my screen is just turning off when the screen timeout value is reached.
my phone is rooted, i have used titanium backup to freeze some of the apps associated with blur, and i have installed the hack to use webtop mode. can others that have this issue confirm if they are running stock or modified software?
***EDIT***

Any of you guys ever find a fix for this? I just noticed that mine is not working anymore either. It's rooted using aRoot but it was working for a while and now it doesn't anymore. I have another couple of days to exchange in store if I want to if it's a phone issue.
Crap, I'm having the same issue now too -- was working fine since I had it, but this occured just today, Day-2 of using 1.5.7 .... wonder if it's related ...

Reboot seems to fix this -- but annoying >_<
Is anyone that is having these issues using bluetooth? I have isolated mine to bluetooth and sent an issue report to Motorola.
same problem here but not using bluetooth
My wife's Atrix does the same thing. "dials or hangs up while in a call". She does not own a bluetooth headset and I have only connected a Motorola 305 one time to it. Reboot fixes the problem. Reboot seems to take forever when compared to my Dell Streak.

Hi I believe I traced the problem with the proximity sensor not working to Handcent SMS. On two separate Atrixes, as soon as I uninstalled Handcent and rebooted the phone the problem went away and stayed away. I have since installed GoSMS and now it happens just sometimes (usually after I install a new app) but a reboot after installing an app ususlly fixes it.
My Phone has a standard Telstra (Australia ROM) and is not unlocked or modified in any way.

If you are using unlocked bootloader or if u have unlocked the dim using a code then u will have to disable the In Pocket detection and then try sounds crazy but worked for me.

Similar issue
Just installed latest stable build onto my Atrix 4G, everything seemed fine last night, although I was using phone with bluetooth, this morning get a call, answer, screen goes dark, red proximity light comes on, and I can hear no sound, [later on the caller said he could hear me fine].
Phone would not wake up right off, and when it did it I still could not hear caller.
Been screwing around with settings all morning to no avail, discovered that the phone will only work with bluetooth device connected. without bluetooth the device goes dark, cannot wake up, have to hard reboot, with bluetooth and volume button awaken enabled, it performs normally, so possible connection to issues in post with proximity but with a bluetooth twist...

Proximity Sensor broken?

Hey guys,
it seems my proximity sensor stopped working. I noticed that my display doesn't turn off anymore when I put the phone to my ear.
I already installed phone tester and in "Sensors" it shows for proximity sensor only "waiting for data ...".
Does this mean I got a hardware defect or is there any other way to reinitialize the sensor somehow?
thanks,
boba

Hey,
no there isn't any response on the prox sensor values, they stay at "null ADC: 0(0,0,0)
I am on stock XXKK5 right now, no modifications at all. Before I was on CM7 where I first noticed the sensor is not working.
Anything else I could try before returning the phone for repair?

Null is actually a default value , meaning that no object is in the radius of the proximity sensor. If you put a finger over the sensor the screen should turn green and the value will be over ~200. Try that.
also go to settings -> call -> Turn on proximity sensor and see if its ticked. if its not , tick it

I tried all of that ... but I can't get any reaction of the proximity sensor, no matter what I do :-( I guess I'll return the phone for repair tomorrow, running out of options here ....

I've seen threads around the web with people complaining about the sensor too. Some guy said he took it to repair , and they changed the entire front panel including the sensors. I guess these things do happen sometimes, bad luck bro. Hope it goes well

disable proximity sensor on GS2 I9100

Hey guys,
I know this thread already exists in this forum but has come to an end with no solution and since its kinda very important to sort this issue to be able to use my phone I thought ill start fresh for some input from the experts.
I have a Galaxy S2 I9100 rooted with a custom ROM(slim ICS 4.1 when the issue started) and it started randomly freezing when unlocking the screen and normal use .but since last week it wouldnt let me make or receive calls as the phone freezes and reboots 10-20 secs into the call..i updated to 4.2 with the hope of resolving this but tht didnt work..I have changed kernels and ROMS(resurrection, cm9 release build)..though the dialer did work for calls on resurrection ROM the proxomity sensor wouldnt work..
so i tried going back to stock sammy ICS (XXLPH) and then the dialer would work but again without the proximity sensor and the samsung tests also confirmed that the sensor wasnt registering...
am rooted now and back to slim 4.2(dont like the look of sammy) with siyah kernel 3.2.2...the dialer and proximity sensor don work..the rest of it is all fine..
Ive done all the wipes each time ive installed a new ROM...also done kernel wipes before installing Kernels..
I think its not a ROM/hardware problem but well it could be but hope to get it sorted through the normal techniques..I cant return my phone for repairs as it was in mint condition bot second hand in UK without warranty papers..
Any help would be highly appreciated..thanks
EDIT: It seems the proximity sensor is to blame for this problem as i found out through other posts..and also i can make and receive calls with the headset/headphones plugged (in which case i assume the phone doesnt try to activate the proximity sensor)..
For now i would like to know how to disable the proximity sensor on the phone..I have tried inserting the gsm.proximity.enable=false in the build.prop editor using the ROM Toolbox lite app n rebooted...but that din seem to work...is there any other way to do this??pls help
I am having EXACTLY the same issue as reported here and it's driving me mad. Did you ever find a fix for it?

I havent managed to find a solution as yet..it seems the proximity sensor and the screen brightness sensor(which are on the same PCB i think as per the unassembling video) have a hardware fault and might need repairing..
Some kernels i think maybe bypass using the proximity sensor if its not working..for now I am back to the SLIM 3.2 ICS rom..It doesnt switch off my screen on call and also no auto brightness adjustment but rest all works ok so am using it for now before i get the hardware repaired..
also the resurrection rom v 2.5.1 works fine in the same manner(havent tested many others..CM7 release build doesnt work)..or you can try that script in build.prop to disable the proximity sensor..
check how it goes..
How about CM9? Do these problems disappear on CM9? CM9 was working well for me but the home key and lock screen never worked. I applied all the common fixes to the keystr file but it never made a difference so I switched to slimics which worked. Then I discovered these annoying call screen off and waking problems :/

I tried checking with the testers for the Slim ROMS..regarding differences in kernel or anything for slim 3.2 and 4.2(3.2 works while 4.2 doesnt) but they couldn't tell me what was the exact problem or the differences that should affect in this case..I haven't tried a CM9 ROM yet but it could work..The kernel for the resurrection ROM is siyah kernel but when i tried that kernel with the slim 4.2 ROM that still didn't work for calls as the phone rebooted.
Have you managed to find a replacement cost for the proximity sensor? also does your screen brightness sensor work?

proximity sensor messes up voip calls

hello everyone
after much debugging of this problem, I think it has to do with battery saving option in the ROM/Kernel.
while having a voip call using sipdroid or magicjack, the proximity sensor turns off the screen and causes the sound to cut off completely. i think the mic still works because i was able to record a voice message while the screen is turned off by the sensor. this also means the wifi signal was still on.
sipdroid has the option to keep screen on during a call. this options works very well. the screen dims but does not turn off completely. on the other hand, magicjack does not have such an option.
why i think it is a battery saving issue is because while the phone is plugged in to wall or laptop, proximity sensor does turn off the screen but the audio is not cut off and everything works just fine.
anybody knows a fix or a workaround for this issue?
the problem is the same on cyanogenmod, MIUI, and Team DIRT. i think i had the same problem when i was using ICS before i switched to jellybean.
thanks
Have you tried the "keep proximity sensor on" setting in the call menu? make sure it's unchecked. Was just asking because you didn't mention it in your post.

yes. it is unchecked. however, magicjack uses its own dialing app. sipdroid is fine because it has the option to disable proximity sensor.
but more importantly, is this a normal behavior? shouldn't i be able to turn off the screen via proximity sensor and still be able to chat? maybe graphics and audio processes are in conflict when the proximity sensor is activated.

i should say, this only happens when the phone is unplugged. i.e. running on battery. i dont know what it is trying to do. maybe save battery. how can i access such settings?
also, i use sipdroid with another voip number. magicjack has its own number and its own dialing app.
I am back to ICS and everything works fine. maybe this problem will go away when htc releases an official jeally bean rom.

Proximity Sensor Issue in Miui and CM roms !!!

Hi All
Any one facing proximity issues here , i saw so many peoples reported in mi forums that when we make a call screen blacks out when we moved to ears( Thats normal) and won't turn back again , so i have to wait the other side person to hangup the call or screen won't turn on power button does work that time, i think this only affects with Sensortek stk3x1x sensor, Redmi note 3 pro comes with two proximity sensors one is from Liteon and other is Sensortek.... Liteon sensors doesn't have this issue, for temporary fix "Wipe proximity area with a cloth or reboot fixes this and it comes back after sometime....( Calibrated but same it works for sometime) no idea wats causing this , issues there in Miui and CM roms....
I found sometimes a flip case with a magnet can cause issues like this when folded right back against the back of the phone, the screen won't come back on because it thinks the flip case is closed.

yeah but i don't have flipcase, this sensor issues starts with those have "Sensortek Proximity Sensor" Liteon doesn't have issue i think....
Flash the rom again using mi flash tool u will find that yr issue will be solved
Or go to test mode amd calibrate the sensor... that's all
Fastboot flash persist persist.img from latest miui rom? I recently had a problem with sensors. The above cured all
@Hemphiz i think that method for dead sensors bro, this one working sometimes it doesn't mostly if we flash a new rom and use no issues but if we reboot the phone after sometime issue starts.... @ra.one i did that bro flashmiui and recalibrate sensor but that works for temporary please check which sensors you got from this app from playstore https://play.google.com/store/apps/details?id=imoblife.androidsensorbox
if you got Liteon Sensors mostly no issues with proximity, if u got Sensortek u will be having issues or once u got issue it will come back..... im not sure why is causing that..... this is really very annoying bug.... Thousands of people reported in Mi forums about these proximity issues on various devices even on newly launched Redmi 3s/ prime may be they have all got "Sensortek Proximity Sensors".......
This is not a bug, You can disable Prevent Pocket dials under Settings-->Lock screen-->Prevent pocket dials...
I had this since last miui 6.9.9 flash.
Disabled prevent Pocket dials and All is working fine
Edit: for a few hours it was working.
Now its the same again. Phone blacked Out After a call and wont turn on, After a few seconds its coming back. As i said , since flashing new 6.9.9

I have sensortec.
But i think its Software related.
Its since last Update.
I calibrate the Sensor and the issue with calls is still there.
Sensor Works fine, test is okay.

Yes i think its software related but, one trick works clean flash the same rom and use it for a week without any reboot...... (DO CLEAN FLASH and Dont reboot the phone)
don't need to calibrate.... for me when i install new rom and use it for a week no issues , if i reboot the phone the issue starts after sometimes.... i don't knw wats causing it so many peoples with sensortek having issues and this bug is not resolved from Miui 7 to Now Miui 8 MM, the issue there in Custom roms im using RR rom i have issues....
Guys For those having issues Check which sensor you got from this app, if u have proximity issues while calling its mostly "Sensortek"
https://play.google.com/store/apps/details?id=imoblife.androidsensorbox
We need Permanent fix....
I also have exact same issue and i have sensortek sensor. But i can unlock the screen while on a call by pressing power button and then unlocking with fingerprint. Bit annoying

So its confirmed its an issue with Sensortek Sensor, no Liteon users reported here, like i told flash the same rom which you are in (clean flash) and don't reboot phone for a week there will be no issues it works perfectly, if u reboot a phone once the issue starts again after sometime so after reboot something is going on no idea what....
i am using this app(for rooted users) on official RR and it works fine

even me used, but i don't think its properly working..... this issue starts only after a reboot, when u flash new roms and after boot dont reboot or power off the phone for a week, not needed any apps, proximity will work properly but once u rebooted issue starts....
But this app's settings load every time phone boots up.so it will work after every boot.
press thanks if I helped u in any way

yes this app i tested earlier, but after sometimes may be in a day or two it won't work....
Found another related issue with proximity , i think proximity is not working properly when there is not enough light around us something related with ambient light sensor i think ..... Eg: if we are in a dark room proximity won't work correctly turn on the light and try it works properly.... i think Xiaomi messed up with something with both sensors Liteon and Sensortek thats why Liteon users face Gyroscope lag in games in dark room and now i think may be the same reason why proximity not working properly in dark room....
hello. I have the BUG but my phone has sensortek version 1 (not 2)
When in a call the screen wont turn off when placing the phone at my ears. With whatsapp the bug wont happend.
I think this is a BUG related to sensor + phone app
A functional workarround is to dial, then press menu (putting the call at background) and then putting the call at foreground again. It works 100% of the time.
Any news? I have this annoying problem too!
