Phone goes blank after call - AT&T Samsung Galaxy S II SGH-I777

So just recently, I noticed that whenever a call ends, the screen remains black and the proximity sensor is still on (red). I've tried pressing the unlock/lock button, but nothing happens. I know the call has ended because I hear the 'ring' that it makes. I've tried it with and without "The power key ends calls", no difference. I have not flashed anything different recently. The only solution I found was to hold down the power button until it restarts, but when someone calls, I have to repeat the process all over again. It was never like this until today. Does anyone know of a solution?
I'm currently on UnNamed 1.3.2 with Entropy's 1/2/12 DD

I'm currently having the same problem with the stock (rooted) ROM... Occasionally after a call, the next time I try to activate the screen, it just stays blank. Sometimes after a call, it's similar to what you described with the end button call staying red and the screen frozen. I have to hold down the on button for 5-10 seconds to reboot the phone. This phenomenon just started about a week ago. The phone has been working flawlessly until then.
I thought that maybe it's some app update gone astray.

I forgot to mention that I found the culprit, it was my screen protector. I had ordered one of SGP's screen protectors since a lot of people were saying it was good, but when it finally arrived, I noticed that it was very sticky and had covered over the proximity sensor. Over the coming days, the screen protector attracted dust due to it's stickiness when I put it in my pocket. You can probably guess what happened, dust was covered over the area of the proximity sensor, causing it to malfunction like that, but after I took it off, all was well, and now I'm rocking my phone half naked - case but no screen protector. I think I'll leave it like that from now on, gorilla glass feels and looks awesome

Call to developers, call waiting issue

Overall i am pleased with the update, but i believe i uncovered an issue that others are expriencing as well.
When i have a second line calling me the screen does not wake up allowing me to switch to the second call. In the past, when a second call comes in the proximity sensor would wake the screen and allow me to take or reject the call. Now i cant even see who is calling. Since i use the phone for business, this is a big, big issue. It still works but the screen only wakes up after like the third ring, whereas before it would wake up immediately Anyone else experience this? I tried this on my buddies Vibrant and its the same thing.
So the question to you guys is how do i get the old dialer app back which i believe controls call waiting. Does anyone else know a way around this annoying issue?
Is there something stopping you from pressing the power button to turn the screen on when you hear the call waiting beep?
The prox sensor is not perfect.

Thank u. I tried the power button, but unfortunately it does not wake the screen.
Thread moved to Q&A.
bump - me too!
pressing the power button results in a lagged response. that is: call waiting call comes in, screen is black. press the button screen stays black. 5-6 seconds pass and then the screen comes on finally and shuts right back off. whereas NOT pressing the power button, the screen stays black for 5-6 seconds and then comes on and stays on.
I am experiencing this problem too. Just started since coming from stock to JI6.
bump... me too, but this happened on a friend of mine's vibrant who was using stock JI6 from the ota, no root nothing and every incoming call if she is on a call has the same behavior.
This issue has gotten so annoying for me, I have unfortunately decided to sell the phone. I loved it, but is failed in the function I use it most as, a phone. Got a g2. Not as glamorous as the vibrant, but it works as a phone.

Touchscreen stops working / random presses

Recently my touchscreen has been acting up on me. Sometimes it will either lock up completely and ill just press power 2x to get it to work again. other times stuff will randomly start to open or if its on the home screen the phone will switch pages left and right at a very high rate of speed the screen almost looks like its flickering.
this just started yesterday, ive ran 2 antivirus apps on the phone and both say its clean so i doubt its a virus, im not sure if its hardware or software related, im thinking about doing a re-flash, but i have a feeling that might not fix the issue..
has anyone else encountered this problem? it can get annoying at times cause it almost stops me from using the phone completely.
Edit: I would also like to note, i thought it was the screen protector i had on, but i took it off and the screen is still acting up
I had this happen last night after I installed a screen protector I got from eBay (they were $4 for 10 with free shipping). I'm guessing it was something in the glue because as soon as I took it off, the phone went back to normal. It always seemed to be 'pressing' in the same spot because I was trying to send a text and it kept popping up with a menu about the contacts info. Also, when that would pop up, the capacitive buttons at the bottom (menu, home, back and search) wouldn't work so I had to lock the phone and unlock it to gain control.

Did any water get in the phone?
i have same problem and make me shock,
my motorola have anti glare screen guard
while iam eat chicken soup and play mini plan , i didnt notice if my finger are wet couz of soup, meanwhile i notice that at that time the touch screen are still good i can play the game, so i quickly try to clean it up using tissue , while i try clean up my phone keep pressing like crazy so i stop to clean it but it keep pressing like crazy, event i have already out from the game, i cannot stop it, so i must pull out the battery and put it back,
i think Atrix the touch screen are too unstable , compare with milestone milestone is better but it's less sensitive then atrix
it normal again after pull out the battery and i clean it up
I never got any water inside the phone, only on the screen protector when applying it to the screen as directed in the instructions for the skinomi screen protector.
the screen protector has been on the phone for 2 months no issues. its only now i see this happening.
i removed the screen protector to see the issue still there.
i have done a factory restore with no changes
i downgraded to 1.52 with the random tapping still going.
i think it might be hardware related.
im going to bring the phone to an AT&T store for a swap

[Q] Proximity Sensor settings too high?

Hi everyone,
funny thing happened to my Mozart. Whenever I make a call the screen shuts off like it should, but it doesn't turn on again when i remove it from my ear until the call has ended.
Which works fine if the other person hangs up, but it means I can't hang up. Whenever I reach a voicemail i have to take out the battery to hang up!
First i thought it was a rom issue, i had just gotten my hands on the mango beta when i first noticed it. I thought it might be buggy.
But the problem remains after hard reset and flashing with a different rom (pre-nodo & nodo).
I found out that the sensor still works. The screen is reactivated when i shine a bright light (halogen spot or so) onto it - but only for as long as the source shines onto the sensor, else the screen shuts off again. wierdly enough, direct sunlight doesnt seem to be enough to trigger it anymore.
since i upgraded my phone with a 32GB microSD I guess I'm not eligible for warranty, huh? but im pretty sure it happen long after and i didn't accidently break something while opening the phone.
very weird... any ideas?
I had this problem on the weekend.
I removed the matt screenGUARD, and the problem disapeared.
Also you can reactivate the screen by pressing the on/off button...
thanks for your comments.
unfortunately, I don't use a screen protector and the standby-button doesn't work during a call
I have this problem also, with stock 7392 rom. The sensor seems to work when dialing, but stops a short time after a call is connected.
The power button works for me to turn the screen back on however...
Where is the proximity sensor ?
where on the device is the proximity sensor located?
I have been having difficulty with the screen not switching on during phonecalls and I have to remove battery to end outgoing calls. Pressing the power button doesn't help either. I don't have a screenguard to remove.
The problem started not long after, but not immediately after my daughter dropped the phone down the toilet. It took a few days for the phone to gently dry out and it worked again except for some residual water between the screen and the glass.

The sensor is about 1 cm to the top and right of the htc logo. It's barely visible and it is dark violet. (Or something like that, I am not very good at naming colours.)
Anyway, I sometimes also experience problems with sensitivity with HTC Mozart, mostly during calls, especially when the proximity sensor has been activated. Sometimes the home button freezes after a call... It's a bit annoying.

Help! Screen Wacked out!

Ok, so my girlfriend dropped her phone and cracked the screen, I ordered a new LCD/Digitizer assembly and everything seemed fine. She then realized that it had a dead line while playing Draw Something. I sent back and just received a new assembly and installed it. Ever since I installed it the screen will occasionally black out and lock up. It takes forever for screen to come back up and seems very random in how long. I try powering off and on to no avail. Once it does come back I get an error log in the notification pull down saying it just rebooted form an unexpected reboot error and I have sent this notification 3 or 4 times.
Things I have tried.
Taking apart and checking all connections as well as cleaning screen on inside and out where proximity sensor goes. I am seriously at a loss, it seems to work for a while on a fresh(actual battery pull) and work fine until it just freezes no button push except power button which shuts off screen and then never comes back except for the captivate buttons on the bottom. I have searched for answers but haven't found anyhing like before.
Thoughts?
Thanks,
Kevin
I know that feel bro.

I've actually had this exact same problem with my phone. I haven't replaced the screen but ever since the update my phone will do what hers does. It will freeze after a bit of use and I cannot do anything with it but do a simpull and then it will work again for a bit. I haven't been able to fix it. I have done factory resets, had the store reflash the software and yadda yadda yadda. I'm havinh my phone replaced now but it's frustrating not being able to figure out how to fix it when I feel like it should be fixable since it literally didn't even start until minutes after I installed the update.
It sucks.

Totally black screen

Had to do a battery pull last night. Had my phone in my pocket for probably an hour, when I pulled it out the screen was black. LED would flash ocassionally and I think I heard a text so everything was fine except the screen. I have Always On off, and I require either fingerprint, a pin, or OK Google voice recognition to unlock.
Tapping the screen, hard pressing or fingerprinting the power button, volume buttons all did nothing. I guess there's a dialog for powering off the device so holding the power button didn't reboot it either. Eventually pulled the battery and it rebooted fine.
Anyone else had this? Pretty disappointed. Haven't installed any new apps in the past few days. I've heard (and had once) a related issue where the phone takes a lot of presses to turn on the screen—in that situation, Always On is on, it's in your pocket so the phone detects and turns off Always On, and for some reason when you pull it out it very infrequently takes a little while to come on. No idea if they're related.
Do you have a screen protector, skin or case installed? Maybe it's causing issues with the sensors in combination with something else?

This just happened to me yesterday. Dropped the phone, and it stayed on but the screen is completely black. I opened it up and tried re-setting the display ribbon cable, but that didn't do anything. Anyone have any ideas what the problem might be?
