Unable to turn on screen during calls

Question

Both of my Galaxy S3s have a problem with their proximity sensors. I make a call, put the phone to my ear, but then if I want to hang up the screen is dead and won't wake up. I cannot disconnect the call until their answering machine hangs up. If they don't have an answering machine, the call just rings and rings until I remove my battery. This is my second S3. Is there a fix for this?

Answer 1

There is a diagnostics mode on the Samsung Galaxy S3 - There is a sensor test you can run to make sure nothing is wrong with the proximity sensor. Follow the link Diagnostics mode

Answer 2

I had exactly the same problem, then set the power button to end calls. But actually if you go to Dialer(keypad), go to Call Settings and untick "Turn off screen during calls".

It works, as I had this problem since I bought the phone so I think it was set to that as default, because I never even knew how to get in to Call Settings before this problem.

Answer 3

It could be that the proximity sensor is being turned off.

To keep it on, open the dialer, tap the left button, and press call settings and select the call answering/ending.

Answer 4

You can activate an option in Accessibility Settings that allows you to end the ongoing call by pressing the lock/power button on the side of the phone.

You can test the functionality of your proximity sensor by entering *#*#0588#*#*

Answer 5

I got the same problem with my S3 as well.

The only solution I found is the one above - the lock/power button to hang up. If you go to the phone app you, press menu key (option key the one on the left of the home button the two line button). Then, go to call settings, then call answering/ending, then check the option where it says the power key ends calls. After you check that, you will be able to end calls using the power button.

I hope there's another solution, but this is what I'm using so far. :/

Answer 6

It could be that a screen protector is possibly interfering with the proximity sensor. Same thing happened on my old phone.

Answer 7

The problem is not just turning off the phone it's putting it on speaker or even getting to the dial pad if you are on the phone with a business. The only fix I finally had to do was make sure that the phone doesn't turn off when its up to my ear.

Answer 8

This was happening to me. I found if I put my headset in, the screen would come on then I could hang up the call. I recently changed my screen protector so this may be the culprit. I changed the setting "turn screen off during calls". Hopefully, this all helps since digging for my earpiece is not very convenient.
