Hi,
I'm new Android user so sorry if my question sound stupid
for a short call the screen will be brighter when i move away my phone from my ear and i can tap on the end button on the screen, but the problem is when i make a long phone call say 30 minutes the screen is turned off (after in dim state for several minutes) and moving the phone away from my ear doesn't turn on the screen back, hence i can't press the end call.
is this the default nature of android phone?
of course i can press the power button to turn on the screen and then press the end call button on screen, but this is tedious and just annoying that i have to press power button and then end call button to end a call.
so how to turn on screen automatically when i want to end call after a long conversation?
Something is wrong with your setup.
As soon as you put the phone near your face the proximity sensor should turn the screen off (not dim, off) then when you move phone away again the screen lights up. The phone screen shouldn't go to sleep.
Check all your settings to make sure you haven't over-ridden the proximity sensor.
What ROM / Kernel / Radio are you using (if nor stock)?

So my DHD seems to not be turning the screen off properly as I hold it against my ear, and for the third time in a week I've just hung up on someone as a result
Firstly, am I holding it wrong? Should it be touching my head?
And if that doesn't work, are there any alternatives (i.e force the screen on or off)?
press the power button to shut down screen display during calls.It happened to me too.
Ah why didn't I think of that?! thank you! That won't affect the call in any way though will it?
You may also try application: Proximity recalibrator.
It is usefull in case proximity sensor doesn't lock screen when you are talking.
I just got my new AT&T S3 a few days ago, and there's a problem I seem to be having with every single phone call I make or receive.
During the call, the screen goes dark, and none of the buttons seem to be able to wake it up again until the other party hangs up. I've literally had to rip my Otterbox off and yank the battery out to hang up during one call to an IVR system that just wouldn't hang up on its own (I guess I could have pressed the right combination of buttons to force a reboot, but at that point I was in no mood to spend 5 minutes experimenting with different permutations of power, vol-, and vol+ to find the magic combo).
Here's what I think might be happening. Note that I haven't exhaustively spent lots of time debugging it yet, on the theory that if it's a common bug, somebody else already has:
Call begins.
Hall Effect sensor triggered by proximity to face. Screen turned off, touchscreen input disabled.
Display settings ticking away in the background force timeout after N seconds. Ignores the fact that the display is already off, and puts the phone to sleep "for real" (at least, the part handling the UI), neglecting to re-enable the power button first.
I'm done with my call. I move the phone away from my face to hang up (or pull up the keypad to enter a selection). Hall Effect sensor broadcasts intent to turn on screen and re-enable touchscreen, and its intent falls on deaf ears because the phone is officially asleep and ignoring it.
Panic. Press power button. Seemingly ignored (though the phone might be waking up enough to see a note telling it to ignore the button, and going back to sleep without further action).
Anger. Press home button. Press volume buttons. Swear violently, and get really mad.
(other party hangs up; lock gets released, phone is awakened and problem seems to go away)
or...
(furiously press various two- and three-finger combinations of power, vol+, vol-, and home until either the call terminates or the phone reboots)
For what it's worth, the same bug show up if I make a call in my car, but the bluetooth call-control button DOES work, even though the phone itself appears to be a darkened unresponsive brick, and triggering a hangup via bluetooth wakes it back up again. I KNOW this isn't due to Tasker or anything, because I've had this problem literally since I made my first call on the new phone to terminate my Sprint account, when it was 100% stock and virgin.
I had the same problem with my white s3 . Then I changed the screen protector and cleansed the proximity sensor with a dust free cloth and haven't had any problems since
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Well, I found the root of my problem: the S3's proximity sensor isn't a Hall Effect sensor, it's near-infrared... and the plastic shell on my case is yellow, which meant it was reflecting too much near-infrared light back into the sensor and triggering it continuously from the moment the LED turned on. I ended up blackening the plastic that surrounds the sensor using a Sharpie marker, and it solved the problem.
Samsung S3 won't hang up
I have the same problem and found that I can insert earphones to phone to make light come back on. After looking at this forum I also noticed a setting (which I haven't tried yet). It's the 3rd from last under settings. Settings-Accessibility-Answering/ending calls-The power key ends calls.
I'm hoping that will work.
Device: S3 with CM10
Basically the title says it all. During the first few minutes of a call, I usually have no problem moving the phone from the face and then seeing the screen light up. However, after ~5 mins on the phone, if I move the phone away from my face to hang up or something, the screen doesn't light up at all. I tried wiping the sensors on the top with my clothes, fingers, anything, but the screen still stays off. Only after I press the power button or home key does the screen turn back on.
I tried googling this but haven't found any answers.
Thanks in advance, you guys rock btw.
EDIT: Is it possible this has to do with the Sleep settings? Additionally, what is sleep? I'm confused about that too.
everytime I make a call on my phone the screen goes blank as if the phone has turned off (the call still goes through).
after the call the screen doesnt come back on.
I have to hold the power button in to reset the phone.
I done a factory resetbut still the same issue.
Any ideas people?

it might be your proximity sensor..
Whenever you make a call and hold the phone near your ear the proximity sensor detects this low distance between your phone and you and turns the screen off (maybe to save battery) ..
it means your proximity sensor might be damaged...
I'd recommend you to download CPUZ and check if the proximity sensor is working properly by holding your hand near and from the phone.. you should get 2 values:
0 cm while holding your hand near the phone
5 cm while holding away
you can also check out the lg hidden menu by typing in dialer
3845#*975# - lg e975
3845#*970# - lg e970
in the hidden menu goto DEVICE TEST then INDIVIDUAL ITEM then KEY PRESS TEST ..
Test it by holding your hand near away as i explained above ..
if the proximity sensor is working well.. I'd recommend you to factory reset
thanks I will give that a go.
btw I have already tried a factory reset.

Hi, did you get your phone working good when making a call? I have the same problem with mine and cant figure out how to fix it.
My RN5P(IND),suffers from a problem that annoys me.
When I make calls or receive calls,the screen automatically shuts down and it wont turn back on again,even if you tap the screen, press the buttons present on the phone.You cant cut the call either.It happens 40% most of the time.Then after a moment only the screen lightens up.
What do I do and do others experience this?

May be it's due to a problem in Proximity sensor.
