Hello!
Are you on stock ROM?
Rooted?
I had the same $%^@! issue with my screen not turning on. This seems to be an issue with many using this phone.
I have had some degree of success using a free app that would allow the screen to come on via a swipe of the proximity sensor.
Have been on both stock and rooted have also reflashed the rom hard reset etc
I went from Stock 4.4.4 to 4.4.2, and I haven't had the black screen issue for nearly two weeks now.
Hope that helps.

The Gyro sensor stop working on my Xperia S with .75 stock rom, the screen will not be rotate at all, I have tried the master reset, still doesn't work. If I use the compass, the screen goes blank and then restart. Please advise
Correct me if I'm wrong, but the phone does not use the Gyro in order to rotate screen. It uses the accelerometer...
And there must be an option to enable/disable it from the settings (I do not have the phone right now to be sure).
You turn it off in option, and you above me are correct.

The problem is the auto rotation option is already enabled, the accelerometer is control the screen rotation, while the gyro sensor detects the movement of the phone, they are both not working for some reasons, if I restart the phone, it might work for a while and then stop working again.
Use this code in dialer and test them

It says function not built in!!
Not built in?!?
Maybe you should head to Sony Service!
reflashed
NO the gyro+ accelerometer are built in the phone definately
since is work in my one !
Did you dropped, hitted?
try to re flash using PCC if not 99% your phone will have 2-3 weeks holiday from you in Sony repair center because it the hardware problem. guess
Tried to restore it to the factory setting, reflashed through PCC. It is still the same. It might work for couple of minutes or otherwise hours, but then it starts not working again. It is really annoying! The funny bit is the display would just stay horizontally, no matter which way I hold the phone while the "auto rotation" option is enabled.
Probably send to the service centre is the only way, as my screen has the yellowish problem too. I need to get it fix anyway.

AUTO ROTATION PROBLEM:
Tried on xperia p
TRY THIS AT YOUR OWN RISK OR ASK PROFESSIONAL !!!
I solved it by opening the phone and then tapping the gyro sensor IC a bit. After that auto rotate started working and no problem uptill now.

We have here a i9300 phone from which the display turns black (as if the screen is switched off) when there is a call being made. The call can not be ended because of the black screen. Home button wont help to switch the screen back to the home screen and the only thing which helps to get the screen back is when the call is answered and the other end hangs up. This happens on different firmware, factory reset did not help. Happens on Omega ROM and om CM10 ROM ... and even on stock which we just flashed back on it. Looks like the proximity chip gets confused and seem to think the phone is kept to the ear. So different Modems have the same result ... Any idea what might be wrong? ... Hardware bug?
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 guys.I have a problem with my LG G2 D802.When I answer a call or make a call,the screen goes blank and the touch doesn't work anymore.I can't do anything else on the phone.The conversation is normal and anything else seems to be ok.Please help! Thank you.
If I answer a call,the screen goes blank,I can speak normally:After the call even the other person finishes the conversation,I still can't do anything on the phone,because the screen stays blank.If I have another call this will awake the screen and it will work normally,I mean,I can take the call,answer and speak on the phone but with the screen blank again. and so on.To have the phone back to normal,I have to reboot it by switching the phone off and on again. Very strange.This happened after I unlocked the phone ,probably because I left the SIM card in ?!!! Any possible advice/solution? I tried soft and hard/factory reset with no results.

I actually had this same issue. my g2 is rooted, but running the stock rom. it has a screen protector but nothing else that would impede the sensors.
I found that this issue never took place in well lit areas. but if at night sitting i a poorly lit room I would go to swipe the scree it would unlock for a second or two and then lock back up. in talking with a friend. I found that the g2 has in set so in the proximity of a pocket or something dark the screen dims back so as to not allow you to mistakenly hit ay button ( i.e. butt dial) i figured my proximity sensor near the ear piece was dirty and causing much less light then there actually was. at the time there wast a firmware update ( which I have now gotten) and was desperately seeking help.
I finally got the firmware update VS98012B and it seems to have solved the issue I ( and you) was having. I would see what version you are running now and then update to the aforementioned and see if that solves your problem.
PM me and let me know what road you decide to travel and if for some reason it doesn't help you we shall figure it out.
Blank Screen
I am having sort of the same issue. But mine is wether in a well lit room or dark room it doesn't matter.
I noticed that it usually happens when i receive a call, after the conversation when i hang up it does not go back to the home screen. all i get is a blank screen. the only way i can get it to generate the home screen again is by pulling down the status bar and going into the general settings and clicking home button again.
during this blank screen i can still see the status bar, and when i bring down the status bar i can see the nav buttons but they are unresponsive.
I also noticed this takes place sometimes after closing an app (noticed on netflix)
I am rooted on stock rom and TWRP recovery. Phone Model [LS-980 Sprint]
I immediately rooted so dont know if issue was there before root.
SOMEONE PLEASE HELP.

I decided to open the phone and check the proximity sensor.I unplugged the proximity sensor ribbon and guess what:IT WORKS.without the functions of the proximity sensor and LED.But at least,I have the keypad and the screen on during a conversation.I have even the knock-knock function.Probably,I will use it like that until a kit-kat update will be available.Thanks for your answer.
VS980 Black Screen
I have a customer phone that I replaced the LCD and Digitizer on. The new screen works fine but...now when a SIM Card is in the phone and I dial out a thin horizontal line appears in the middle of the screen and then the screen goes black.
If I remove the SIM card and place a call, the phone gives me the standard "Emergency Calls Only" and goes back to the dial pad.
The SIM Card is not activated but it is recognized by the phone.
Has anyone else had this issue? I tried a factory restore with no luck.

Hi,
I have the same issue , my screen turns black when calling or receiving calls , i m not really good with my hands... so do you know other solutions to disable the proximity sensor ?
thanks
Same issue here - LG G2 screen turn off and goes blank during conversations
I have exactly the same issue - LG G2 D802 screen turn off and goes blank during conversations.
Thanks to @Bam9 and @EtherBoo , who suggested to clear the proximity sensor from the outside and squeeze the top left corner of the phone, I tried to clean it and put some stress on it - and it worked!
Another issue which I also have and is also caused by the proximity sensor is that the screen stays on and the touch buttons in the dialer aren't responsive - which means we can't switch to speaker, add a call, mute, etc... However, the main touch / navigation button (home, back and menu buttons in the bottom of the screen) are responsive, in addition to the status bar.
(This issue was already reported by @athorax here)
In both of these situations the only quick way to end a call is to pull down the status and notifications bar and hang up from there.
I have a glass screen protector (which don't block the proximity sensor), and I am rooted and using CyanogenMod 11 ROM.
I used ioroot to root and AutoRec, which comes with TWRP 2.7.0.0, to install CyanogenMod ROM.
However, going back to stock ROM (in my case, LG G2 D802, it's D80220C) won't help since the issue still exists.
What I'm sure is that it was pretty much okay in the beginning, and the situation became worse and worse - occurring randomly, until it arrived to a situation in which I can't use the phone properly during conversation.
Now that I discovered that I can put some stress on the proximity sensor it seems that I have a hardware rather than a software issue.

So for you it was a software issue?
Is your sensor working until today with no issues?

I'm also rooted and with TWRP.
Did it happened before you rooted?
Did you used ioroot to root andAutoRec to have TWRP?
You see, I'm really trying to find the similarities between us all in order to solve this issue...

We already have KitKat based firmware update. For me it's D80220C.
For you it might be already D80220D. Use this link to check your version, and replace the IMEI in the end of it with your IMEI.

When you place the call you do hear that the call is made?
If so - then you have exactly the same issue.
What is your model, what ROM are you using, and did you root your phone?
I have LG G2, unable to make call. The signal strength is fine. I have tried reinserting the sim. but i am able to receive calls. when i make a call the dialup screen come up and call ended automatically. Any Help
I have problem that maybe someone knows how to fix. My screen goes black (screen off) when i make call or recieve call. Anyome know what the peoblem and how to fix it.

İt is becouse glass screen protector. Android 5.1 has some changes on proximity sensor and that couses the problem with glass screen protector.
Mine has no screen protector but keeps going black when I make a call to it can't cut call off unless they do
I never put any screen protectore on it. Its all original from sony with sony logo

I had my screen replaced
After I had my screen replaced it did this. I was racking my brains as to why...
I read somewhere it could be recalibrated but you had to do it in Android 4.4 kitkat (not 4.4.4)
For some reason you couldn't do it in lollipop. I thought, what the hell. Backed up all important files. Flashed kitkat found how to recalibrate and it worked then on like a charm.
Phantomrocks on the sony forum says...
"You have to sacrifice resetting the phone using the Sony PC software 1st. Avoid data backup from old accounts.
Then, after the reboot is done and Android is reinstalled with update x.x.x.534 goto the dialer & type *#*#7378423#*#* then press dial
In the menu that will come go to calibration and then choose proximity sensor. (If you run the test it might give error = -1) Then, set settings to default and it may ask to reboot the device.
After reboot type *#*#7378423#*#* then press dial. In the menu that will come go to calibration and then choose proximity sensor do the test and it will show success. VIOLAAAaaaa!!!!"
I just did a factory reset and lost my data to solve this problem
I wish i knew this before
Did you solved the problem?
