I can't remember which rom I'm on (probably the one in my signature, can't remember if I updated it since then lol), but I've been having this issue for a little while now, but sometimes (can't quite figure out what triggers it) I lock my phone and my screen won't turn back on when I hit the lock/power button to turn it back on. Also sometimes I go to lock my phone and the screen will turn off then immediately back on, showing the lock screen. I love everything about the rom except this bug. I don't want to have to pull the battery constantly and it's getting very annoying. I do know I'm on 3.6, but can't remember which rom I'm on. Please help!
Flash different rom? If it sticks on another rom, it's a hardware issue, and you should get it replaced by Verizon
I had this same exact problem I posted about a while back. I linked it to my use of turboprop. Everytime i hit the on button the backlight would turn on but the ui would never come up. Reflash your rom and not turbo after a good wipe. my problem got fixed.
I have Speed Rom 5.1 on my Amaze. When I am finished with a call, the screen stays black. I try to hit the power button, but nothing happens. I have to remove my battery in order to reboot. Can someone shed some light on why this happening? I am thinking that it may have something to do with my CPU Tuner settings, but I am not sure.

Probably that or a bad flash, just reflash, see if it solves the issue.
Most likely it's something simple, like an issue with your proximity sensor. I know there was an app that could calibrate that but I forgot what the app was.
Stock Rom - Black screen while phoning
There is a similar problem on my wife's phone with a stock rom (not rooted Amaze from T-Mobile). When making or accepting a call, the screen will instantly go off even without leaning the phone against anything and won't turn on unless the power button is pressed. Sometimes the screen would turn on by itself after a while after the other phone was hanged.
I've downloaded AndroSensor app: the proximity value does't change even when touching the area near the earpiece. It keeps showing ( 0.5mA ) 3.5 in.
I've found a thread which is there since april 2012 and describes quite a similar problem.
okay.. i just the original post date for this thread.. please don't bring back threads that are 6 month's old which issues might have been solved already since no ones been posting in it for 6 months...
(anyways) this is what i was gonna say
on my current s3 when my phone is placed to my ear it cuts off the display.. and if you pass your hand anywhere near the sensor's to the top near the camera it cuts off the display.. maybe there's a feature like that enabled on the stock rom also.. or you could possible check with the system settings to see "screen" on/off settings in display or power saving mode.. or something...
Thanks for the answer. I didn't notice that the thread was that old. I think I will keep up a newer one. But the current issue isn't likely to have been solved.
The problem doesn't seem to be triggered by wrong sensor measures (because the screen will go off even after disabling the sensor) nor does it depend on the rom version (same thing on the CM10).
Resolved:
It will sound stupid but I have found a simple solution:
I have just wiped the screen in the upper left corner where the proximity sensor is located and it started behaving normally. Though I don't use any protection tape on the screen it seem to have become less sensitive because of mud or sweat.
Hi everyone !
I'm new here (and not a native english speaker, so apologies in advance for any grammar mistakes)
Before making this thread, I looked for info here, but I'm not sure for what to search.
I'll try to explain my problem here.
I bought a Galaxy SIII from my provider 3 weeks ago and everything looked fine, till last week.
Some times to time, with no apparent reason or cause, while my phone is on sleep mode, on my desk, or in my pocket, playing music, I have the following problem: when I push the on/off button to wake up my phone, my screen is turning on, taking me to the lock screen.
But, my screen brightness is very low, like set to the minimum.
And when I draw my unlocking pattern, screen goes black.
Bottom buttons are lit and my phone seems to be OK, I can feel haptic feedbacks.
But the screen is black.
If I push the on/off button again, screen stays black and bottom buttons are not lit anymore, as a usual Sleep Mode.
If I push on/off again (depending on how much I wait between 2 on/off):
- My phone awakes from Sleep and takes me again to the unlock screen, brightness still very low. And after the unlocking pattern traced, black screen again
- If I didn't wait enought after putting it into sleep mode, in this case, I don't have to redraw the unlocking pattern. I'm back to my home screen...
for 1/4 of a second, stilll with brightness at the minimum. And screen goes black.
And after a serie on onoffonoff, boom, my screen is back to full and normal brightness and everything is OK.
At the beginning, my phone did that once in a while. I thought at the time ti was after pushing the on/off button while using a CPU/RAM hungry app, my phone struggling to recover....
But now, it's totally random.
Depending on .... I don't know what, I have to do the onoffonoff thing 2, 5, 10, 50 times in a row so my phone can recover from is half comatose.
Yesterday, I could not use my phone for half an hour ...
and if someone calls me, I hear the ringtone, but screen stays black.
I can answer the call (but not knowing who's calling) by sliding on the part of the screen where the slider normally is.
Funny thing is about removing the battery. It doesn't solve my problem.
When I do so, my phone boots, I see the "Samsung Galaxy SIII" boot screen, on low brightness (whih is not normal ...)
After that, I normally have another boot screen with my provider's logo and tone. But screen goes black again (but I still here the tone)
Then I realized it started to happen when my phone proposed me a Samsung update.
I tried to reset my phone to factory settings but it didn't work, the update was still here.
For a while I thought my problem was solved, because my phone behaved normally for 3 or 4 hours, without problem.
But it came back.
I found on the internet several "almost-same-problems" without proposed solutions.
Like checking if the proximity sensor was blocked by a protective transparent plastic sheet, or a case.
I tried to to remove mine.
Didn't work.
Some people said it was linked to their phone trying to acquire a wifi network.
My wifi on or off, withiin or without the range of a wifi router didn't work ...
I tried to note things down about what I did, when, how, app launched before the problem appears.
I checked battery info (temp, voltage, etc).
No pattern emerged.
So.
Hs anyone of you enountered the same problem ?
Do you have ideas, solutions I can use ?
Or maybe a voodoo prayer ?
I could sent it back to my provider which will bounce it back to Samsung. But it will take ages (3 to 4 weeks ...) :'(
Thanks in advance !
do a factory reset, go completely stock
if that doesn't help, send it in

That's what I did.
I tried by going into the Parameters menu, and reseting.
I tried by booting my phone with Vol+ / Home / Power buttons to access a console mode and do a wipe data/reset.
The problem is that my phone got an update like one week ago from a 4.?.? to 4.1.2.
And even with a reset, my phone reboot with the 4.1.2 version, which seems to cause this problem.
Or maybe not, but I can't be sure.
As I said, after a factory reset I did yesterday, everything went well for 3 or 4 hours and the problem reappeared.
send it to the service
This phone has never been modified, no custom ROMS, never rooted, using the latest OS from AT&T ...
And today, for whatever reason, when making originating a phone call, and once I've hit "dial" ... the phone screen goes completely black except for the status bar at the top (the one you can swipe down). I'm saying that whereas usually, after hitting "dial" and as the phone dials, you can actually see a screen full of information (hang up botton, number/name of who your dialing, etc.) ... in this case and now, there is just a black screen.
Though there is a black screen (other than the status bar at top), I can still hear the phone ring and even have a conversation should somebody answer. But when the call is over (the person on the other end has to end the connection because I have no screen interface to do such), the screen remains blank (other than the status bar at top) and none of the bottom, permanent keys are operative either ("home" / "back" / settings / etc.). To get back to the home screen, I have to pop the battery and re insert it and re start the phone. But even then, it's acting weird: when booting, at the "Reimagine Possilbe" screen (I think that's what it says) it hangs there for about 45 seconds (usually only about 5 when functioning correctly) and will eventually end up at the home screen.
But if I originate a call, the cycle repeats.
I've completely reset the phone to factory defaults at least three times, formatted the USB storage and the whole nine yards but it remains glitched as described above.
...
So... has anyone seen/heard of this?
I'm thinking of just warrantying the phone as it's only about 5 months and I figure AT&T should have no issue as it's such a replicable problem and it certainly doesn't seem to be software related as it's completely stock and multiple factory resets have not worked but wanted to put a line out here first to see if anyone else has experienced this.
Thanks in advance for any information.
Best,
Joel.
I think the network is fugazi right now, as I had issues with the phone, and read about another user having same troubles. I'd give it a little time.

I sure hope so. Even though I've reset the phone (which sucks) ... I'd prefer that over having to go to the store and all...
Odd that a network problem could cause such, though ....
Thanks for the word ...

Just a llittle update ...
I changed the "Proximity Sensor" to OFF and now the normal iin-call screen appears but it never goes away, which can be problematic.
In general, I've always had the proximity sensor set to ON as this allows the in-call screen to blank after a few seconds (complete blank with no status bar at top) and then reappear when I remove the phone from my ear.
But when I re enable the proximity sensor, now ... the screen blanks immediately (excepting the status bar at the top) and never comes back ... even after my call recipient ends the call ...
I'm just gonna warranty at at the local service center; at this point (two days now with all my friends AT&T phones working fine) I'm pretty sure something is glitched with the internal sensor that manages the proximity settings ...
Thank God for warranty.
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
