This is known issue that's plaguing sony Z2 camera. hardly any solution for this problem.
it's not actually an apps causing this nor the mother board is defected.
today i found the actual problem.
the Camera hardware itself is damages/broken (probably because of overheating when using 4k video or when using your phone extensively). basically replacing it would pretty much solve the problem.
anyway, i hope this helps everyone who has the same problem as i do.
cheers :highfive:
UPDATE: turns out it is just a temporary solution, as the camera failed again and the black screen came back. overheating is the cause, yep.
the camera hardware also includes the LED?
Nope. They're separate.
so i have a problem with flashlight apps too. When trying to turn off the LED it stays open. Also when starting-trying to turn it off from the quick settings menu, the led shortcut disappears. and the LED stays on. And i saw that this problem is connected with the camera. Because if it happens that the camera works well, if i use the flashlight the camera will not start. If i do not use the flashlight, the camera may work well for about 1-2 hours.

I currently using xperia mini pro sk17i,and also using cyanogen 2.3.7 ver.but my phone screen will blackout and unable to turn on whn i made a call.kindly tell me what the problem and how can i fix it.thanks alot!!
looks like bug in proximity sensor.
Hahahahaha!i fixed it!and that was easy!!took me a whole day fot this!!thanks alot dude.XD
what was the resolusion?Im running stock rom and have same bug sometimes.
Probably screen protector (or, dunno, dirt?) bloquing both proximity sensors, thus the phone thinks you have the screen at your ear, so as soon as this function is activated (a call is made or received) the screen turn off.
Easy check, go to services menu (dial *#*#7378423#*#*, go to "Service tests" and then "Proximity switch".
If its ON the whole time, the sensors thinks something is near the screen, it should turn ON only if you cover the sensors (located at the upper left of the screen, beside the speaker), and off if you uncover it.
If no screen protector or dirt is found there, maybe its a software issue (custom ROM), but on stock it should work, else probably a faulty hardware, take it to repair.
Hello,
the following problem appears when i try to unlock the phone after some hours: i can see my home screen, but the screen stays extremely dim. When i try to start an app (e.g. browser) the screen turns black. I can unlock it again, but the screen stays dim. after some unlocking the screen becomes normal (normal brightness) and also the apps are startable.
i am using autobrightness, the stock firmware, 4.1.1 (i9300xxdlih) power saver is not turned on.
thx, i hope you can help me solving this problem

i updated mobile phone to android versiopn 4.1.2. this morning. Unfortunately the problem still appears.
Maybe its a hardware defect?
Try to disable somehow light sensor and change settings to non auto brightness.

i disabled auto brightness and set the brightness to the highest level. But its still same: very dim and after a while a black screen; after a few times of unlocking, the display works normally
I have just seen the same issue on a friend's S3.
Anyone else? I feel like this is a very big issue that is still lurking in a lot of devices.
I tried it myself and I toggled the power button to turn the screen on and off.
It doesn't take long but sometimes when the screen turns back on, it's super dim and you can faintly see the lockscreen image.
You have to cycle the screen several more times to get it to the 'correct' brightness, and no it is NOT a brightness setting.
It's some hardware issue in the phone.
Sorry for the necrobump, but I only found this thread. I have this problem too since about a week back. It makes my phone useless at times. I first thought it was a software issue. I have an app (called Twilight) for dimming the screen more than normal settings and also toning it, for nightime use, and I thought that was the culprit first, but nope. I have flashed rom, recovery, wiped all caches I can think of. Still happens, just now I was in the middle of installing android revolution hd, and the screen ultradimmed on me so I can't finish the process
Thing is, a few months ago I managed to crack my screen by way of gravity and concrete. I let the samsung brand service centre in Stockholm repair it for me (it is out of warranty) and this issue with the dimming never happened before that. Then again, it didn't happen directly afterwards either... but still. So, I am thinking: either me dropping it caused more damages and this is because of that. Or the service center did a bad install of the new screen. Or, the replacement screen that was installed has a defect in itself. I am leaning a bit towards the third explanation... maybe different batches of screens?
Does anyone have any ideas? If I am to contact the service center and complain about their work I would like to be able to point towards a "known problem"...

Take it back, if it didn't happen before then the new screen is most likely.
It isn't a common problem
Hi all, i have a LG L7 II P714, and my WhatsApp is experiencing a weird problem... when someone sends me a audio note, when i click it to play, the screen goes black (in the chat part, but the green line in upper side stays with less brightness), i first thought it was a problem with my battery, or screen, but i found that other smartphone users are experiencing the same problem, here's a video i found showing the problem:

My WhatsApp version is 2.11.152, is there a way i can solve this problem? Thanks for the attention!
I also have this issue. The screen is still barely visible after clicking a voice note when it goes dark. However I can just about make out movement if I scroll up and down the conversation almost like the brightness has been extremely turned down.
If I click back the screen returns to normal. Very strange!
On a Samsung Note 3 running Kitkat 4.4.2 and Whatsapp 2.11.186

I had this issue before until i found out it's not really a problem, it's only one thing i used to do wrong without noticing. When you play audio note on whatsapp don't put your hand or fingers on the sensor next to the front camera, because if you do the sensor will make the screen go off, it's just like when you make a phone call and you put your ears at the speakers the screen goes off by it self and actually the sensor is doing this so you don't press anything with your face while you on the phone. I don't know if this make any sense but i hope it helps lol
Its Because of the proximity sensor it routes the audio to the earpeice instead of the speaker

Thanks for clarifying,
however, I am holding my phone in my hand and, as I click the whatsapp play button, the screen immediatly goes dark.
Is there a way to disable this behaviour for whatsapp?
Thanks

The case on the phone may be tricking the sensor, i took my phone out the case and the voice notes started to play out the loudspeaker

I have a "naked" galaxy note 2
I also faced this problem on my Samsung Galaxy Core Prime SM g360h. There isn't a problem with your device. It's a whatsapp bug. While listening to an audio note, keep your hand or face or anything else away from your phone's proximity sensor, usually located aside of the front camera. This helps almost all the time... The proximity sensor is used to turn off your device's screen while making a call. Whatsapp believes that you're making a call while you're actually listening to an audio note, thus triggers the sensor to turn off your device's screen... just keep your hand away from the sensor while listening to an audio note.... it'll help

Thanks, but it does not help with my Galaxy Note 2
mmmhh i have the same problem. It has nothing to do with holding my hand somewhere. Could this be a bug? I had this problem afther flashing a custom rom. Everything worked fine, accept Whatsapp voice message. And i do use this a lot
Someone with an idea?
I have the same problem, even when my phone as nothing near the sensor, when i play the voice mensage he goes black
there are no xposed modules to this?
using Galaxy s5
I too have the same problem. I am not blocking the proximity sensor. I can't even take back the control of the device till the entire audio file plays completely.
A lot frustrating.
When I press the back button the voice comes back for a second and again nothing.
Please help.
Same problem here, Samsung Note 3, Note 5 and S7 Edge! The screen goes black, but that's not really the bad thing here.
Besides that, the audio usually stops too!
Had the same problem
Something that worked for me ,on my Sony Xperia z3 compact - there is an xposed module called Sensor Disabler. Change the setting of the proximity to remove sensor, reboot and it should work.
The solution for this kind of problem is. Go to 'Setting > Sounds & notification > Interruption' then untick 'events & reminder'. That's it....
Hi everyone, I've had my Moto Z for a couple of days now and am pretty happy with the device - even with the battery life I have one small problem, however.
Sometimes, when the screen is turned off, the Moto Display approach action won't work. In these cases, I also notice that the bottom right IR sensor isn't lit up - which it usually is when the display is turned off. The approach action only starts working again when I pick the phone up. This is very inconvenient and not how it's meant to be.
Is anyone else experiencing this bug?
At first I thought it might be an issue with Doze putting the process responsible for the Moto Actions to sleep, but after whitelisting all Moto apps the issue still sometimes occurs. I have not yet found out under which circumstances this happens.
Any help would be greatly appreciated!
EDIT: It seems this issue only occurs immediately after turning off the screen, after which there is a slight delay (a couple of seconds) before the IR sensor is activated. I will observe if this is really the case, which of course would render it a non-issue.
Hey guys i bought this phone few days ago i am facing proximity sensor issues right now
when i try to call someone it will randomly go to dark screen
proximity sensor in testing apps does not work correctly
i tried removing the screen protecting glass and case it still persist
i thought this issues might have been fixed with the new update it doesn't guys should i return this device and get new one
Mi 11x pro uses a ultrasound chip for the proximity sensor and this works combined with other sensors like the gyro. So when you put the earpiece to your ear it detects an orientation change and switches the display off. I'm currently on indian miui v12.5.2 and don't face the issue you mention. Slow movements are known to confuse the phone. Other than that the screen shouldn't switch off after initiating the call unless you change its orientation. Testing apps work with orientation change.

Almost all of the sensor apps fail this, but in call I have no problem whatsoever.
Are you having trouble during calls?

Wow, new info, didn't know that, thanks
I have the same problem on my Mi11i... well... my problem is that the screen wont turn on when I move my phone away from my ear... the screen stays off, i cant get it to turn on even if i press the power button. Annoying as hell... You call someone, he doesent answer, and you cannot cancel the call because the screen is black and no way to turn it on! Or to check a phone number or email.... I will send it back as a warranty isue....
The problem is with MIUI 12.5.4.0, we need to wait for the fix with newer version of MIUI or try to install xiaomi.eu ROM
Hi Guys, i'm using Xiaomi 11x pro version 12.5.2. I'm facing proximity sensor issue also proximity sensor option not available in my phone in incoming call setting. please help on this.
