[Q] Black screen in phone call - Samsung Galaxy Exhibit 4G

Would have liked to posted here but can't cuz im new..http://forum.xda-developers.com/show...218644&page=17 dementemusic's post.
I have a stock sgh-t679(Galaxy Exhibit 4g) that I have rooted and tried many of the custom 4.2.2 roms over the last few days. All are excellent. The main roms I have been playing with are AOIP, Linaro CM10, Paranoid Android, Baked Black Bean 8, and SlimBean 4.2.2, I did try AOKP 4.2.2 as well.
On everyone of them except Paranoid I get a Black screen while in a phone call or when i place a call. Phone will not respond. I feel it vibrate when i push power button but can't do anything with it while in phone mode. I had to select the option to end call with pw button just so i could end calls.
Now with Paranoid the only time I get a black screen with no wake-up is when I tilt the phone onto its back, screen facing up. Moving the phone around in any other direction the screen stays available.
Any help with any of these issues would be most helpful.
Thanks to all the people that take time out of their busy lives to make kool custom rom's. It's just awesome!!!

Are you sure its a black screen and not dimmed? I know when I use my phone to make calls (not often) my cheek activates the notification sliding brightness. Try unchecking that

Boy am I a brick lol. I figured out why my screen would go black during a phone call. The screen saver was covering the proximity sensor, making it think it was near something and shut screen off. :good:

Powering off qustion????

his phone is not on silent ethier?????
If you could write your question in understandable English, you'd have it answered by now.
I just got a Brand new Nexus one phone and i noticed when i power off the phone it makes a chime sound and trackball light up then screens goes off on the other hand my friends nexus one phone when he powers off, it vibartes instead and lights up but his phone isnt on silent? why is that? also the screen on my nexus one phone is like so new its hard to slide my fingers? is that normal?
Fingers don't slide well on the screen when they're even a bit wet, that might be an answer to n.2.
Enable "always vibrate" in notifications (default is "vibrate when silent"), and you'll most probably have the same result (not that it matters - it's just the phone being turned off, who cares what it does on the way there...).
where is that, im in settings and i dont see vibrate when silent

[Q] 2.3.4 screen issue on Nexus One

Hi there
I'm quite happy with my Nexus One... a very nice change from my old BlackJack 2. However, I have one issue.
When I get an incoming call, sometimes the screen won't wake up at all. Pressing the trackball, etc. does no good. I installed a program called noblock and now it's waking up after the call is over, but the other end has to hang up first.
This has to have something to do with the screen lock in relation to the proximity sensor or something. I'd really love it if I could just set the screen lock to manual, so I can press the power button to turn the screen off and on, getting rid of the slide to unlock screen entirely.
I tried a fix from an older thread to disable the proximity sensor, but it had no effect. It was adding a line (gsm.proximity.enable=false) to build.prop.
Can anyone give me a direction to go? Thanks!
i have some issues with turning my screen on sometimes, it will come on briefly and turn off with just the backlight for capacitive buttons on
2.3.4 ? Are you sure ?
It's some CM nightly ?

Nexus one screen gets really dim

Please, any input is useful. ):
I just bought a nexus one the other day, and i think I was scammed. THe power button works fine, but occasionally, the screen would get super dim. It doesn't black out because I can faintly see all of the icons and menus, and I can tap them. ALso, its not automatic brightness, because its horribly horribly hard to see. Pulling the battery (sometimes) fixes this problem.
I'm currently running Kang-o-rama with SP2.
Has this ever happened to anyone? If so, how did you fix it?
It does sound its the auto brightness. If you're outside and its dims it is very hard to see. You the default android power widget to test it. It has brightness toggle on it. Full /auto/dim/ and basically the middle.
I'll take a picture of it once my dad comes home, but I tested it last night if it was autobrightness.
I waited for it to dim, then went into settings, disabled autobrightness, and put the brightness all the way up. It was still super dim, and didn't return to normal until I pulled the battery.
I would look for support in the thread for that rom. Or flash another rom. Sounds like it is just a bug in your rom.
I just installed a Miui rom hoping it'll fix it (cause I was using cm7 based roms) and it worked for a while.
Now it began to Flicker and finally turned off. It'll ring when phones call it but nothing will show on the screen. I'll pull the battery but this time nothing shows up (though it vibrates indicating it turns on).
I know this is a hardware problem now, do you guys know what part it is?
Please, any input is appreciated.

My screen always turns off during calls . . .

. . . and I have to hit the power button to turn the screen back on. To be more precise, the screen turns itself off when I hold the phone towards my ear during calls, and it does not turn itself back on when I hold it away from my ear.
This is obviously some power saving feature that doesn't work as well as it should, like a gimpy proximity sensor. Anyone know a workaround for this ?
I'm on Three Musketeers Sense 3.6 ROM.

Well, ther is a proximity sensor there, near the camera on the top of the phone, on the screen side, and this screen-off thing is more like feature to save power and not to anoy you during the night when you talk to the phone
Don't know why it does that, maybe your sensor is faulty, but try to flash a different ROM and see if something changes, also make sure you don't keep your hand or finger near that sensor, just to be sure, i personally use this ROM and i don't expierience this issue.
Hope this helps

I actually have this EXACT same issue and it is really annoying me.. I have a feeling it is the senor that is faulty, because I haven't even rooted my phone yet.. so everything is all on stock....

Oh, dear
If only there was some way to turn off the proximity sensor like in my Galaxy S2.

If it is possible on Galaxy S2, then it is possible on any android phone , and it is, but there should be made a tool for that or a flashable zip, i'm not that experienced to tell you exactly what needs to be changed, but it can be done, that i know
Same problem here.
Changing roms didn't solve anything
Anybody have solution for this ?
If you have a screen protector covering it then it might be wise to make a cut out or take the protector off altogether.

as i remeber , you can write something in the build.prop that will disable proxy sensor
Im having problem that is almost same. After a long call(when screen is turned off) it turns off but screen or softkeys dont reply any way.
I have to turn of the screen with power button and let it be around 10-15 seconds and turn it on. Then lockscreen appears and everything
works. This is really annoying because I cant cut the line any way.
Not using screen protector and tried couple of custom roms. Allways have the same issue.

No I don't have screen protector or cover.
Problem is identified with proximity sensor itself, on App " Android sensor box " if you select proximity sensor it reads always 0.0cm no mater what you do with phone.
It seems like HW failure, will have to look at it in more detail.

I have tryed few Apps that will lock/disable proximity sensor but without success. It either acts the same or don't light the screen at all.
Anders can you help us with writing some code, I'm willing to be beta tester if you like ?

The problem is when you try to make a second call display turns off, phone is working you can talk, but you can't end the call or nothing because screen is off, so you have to turn it on or wake it by pressing power button.And it's happening only on every second call, so I make a first call, as soon as I try to make a second display turns off, and only power button wakes it, after that you can make the next call normaly, but problem repeats on second call.
Phone was stock on ICS 4.0.3, and making problems there. So it's now fully unlocked ( S-off ) Hboot is 1.28. I have tryed many custom roms, but the problem repeats
I think it's the hardware problem with proximity sensor.

I think too. Sounds like your proximity sensor is weird.

To continue the story, I removed the MB and when the proximity sensor is out of the case, it works ok. When I put it back in case( behind screen ) it doesn't respond again.
Cleaning didn't help, will have to find another one to make sure what is the problem.
I have fixed my problem thanks to this thread

Screen stops responding during call

I've had this problem with 2 different roms now (PureNexus, Chroma) on a few kernels (stock, ElementalX) so I'm not sure whats causing it but I need a fix. In a call, many times the screen just stops responding. Sometimes I can turn the screen on/off using power button and its fixed. Other times nothing works and I have to do a hard reboot by holding down power key since nothing else works on screen.
This is on latest version of the rom/kernels. Any ideas?
When you say its stops responding, do you mean it goes dark and nothing displays on screen? Or that its on with everything displaying but tapping it does nothing?
Only when in contact with ears?

Its on, touch doesn't do anything. The phone is working since volume keys bring up the UI but you can't do anything. Also proximity sensor works, it turns on/off as I bring near ear. I don't have a screen protector.

I'm having a similar issue from the last month.. I'm on DP5
when i get a call most times the screen is off.
To answer the call i've to put on the screen, unlock the phone and then go to the heads up notification and choose answer there..
waiting for nougat final hoping it'll fix this.
Tried fiddling around with notifications importance setting.. it helped a little but then there was the annoying heads up showing along with the regular incoming call screen.
Sometimes (very rarely, has happened twice) the screen just remains black and will only work normally after a reboot.
Anybody have any suggestions?
I was having similar issues, also on the Developer Preview and I ended up noticing that the phone app was blocked from showing any notifications despite the fact that I never set it that way. I would hear the call ringing but would never see the screen to answer. Just changed that setting and everything was back to normal. Perhaps something is causing the phone app to fail to show notifications for you as well.
