[Q] Accidently dropping a call with your cheek

Hello guys
Me and friends using DHDs are having the same problem.
Sometimes hangup the calls with cheeks or ear or ....
Especially it is annoying then you in rush with something, receive important call, hold your phone between shoulder and ear and .............. after some time you accidentally press END CALL button.
It is the biggest minus having touchscreen phone.
The thing is that screen turn offs after some time of talking but it turns on again as you are moving around.
Did anyone find out how to solve this misery?
Would be grateful.
Regards

Sounds like an issue with the proximity sensor, if I hold mine wrong I tend to turn on loudspeaker with my face. It's tweaked in some of the ROM's I believe - are you running a ROM or still on Stock?

Hi, thanks for responce.
I have rooted sence 3.0 Rom by nitr0. But this problem is not dependant on my rom as before i had original virgin mobile branded rom and the problem still persists.

By the way.
Are there any way of adjusting proximity sensor?

Definitely a proximity issue. On CM7 I also had the issue of putting calls on hold with my cheek! You can remove the hold button in the call options.

yes. my screen turns off only when i close proximity sensor totally. though it should do it in a distance.

Unfortunately indigolemon's posted app does not work on my kernel. as my radio is 12.65.60.29_26.14.04.28_M. and Kernel 2.6.35.10.

In cm7, this accidental hold was a b**ch before i removed it; but it took me quite some time to figure it out

Screen Goes Dark During Call

Has anyone ran into issue where you make a call screen goes dark like it's supposed to however if you want to end call screen won't come back on until call ends on the other side. So if person doesn't answer I have to wait till voice mail picks up and hangs up on me after it times out.

Is your fone rooted ?

It generally happens when I put it on my ear. Otherwise it is always on.

Phone isn't rooted. I have tried to hit all the buttons including power to turn it back on after it dims out and still nothing. I'm thinking of doing business factory reset but I rather avoid it if I could.

It happens when you place your finger or any part of the body near the sensor.

Got a screen protect covering the proximity sensor? Yours might be too sensitive. I had the same problem with my n4. Solution was no protector or wait till dearth or whatever brand you use to not cover the sensor. That was the first and only phone I ever had that issue though.

Did reset still same issue. I'll try without case, however I have had no issues with case till now.

Also heard of this bug in a German Android forum: there have been some users reporting the same problem without screen protector or case. Still don't know why this happened but You're not the only one with this bug

You can always go into the accessibility settings and set the phone to end a call when you hit the power button

Yesterday I wanted to read a numberplate from a picture to the person I was talking to. Had to text it to him later because the screen wouldn't turn on.

Enter *#0*# in the keypad to open the "test menu".
Press the Sensor tile and test your proximity sensor's function bij moving a finger over it.
If it does not change value from 0 to 1 and make the screen go green, your proximity sensor is likely to be broken.
Replacing the front camera (which houses the proximity senor) will then fix your problem.

press the home button or power button

I went into store today to speak to a tech that used to work with when I was a sales rep @ sprint. He told he has seen issue a couple of times. He says when that happens its a sensor issue. More common with fones that where 1st shipped out. He could of replaced it if I wanted but he wanted to avoid giving me a refurb. He did a couple of tests and it's been working since. He suggested if it happens again to bring it back again.

Works after a reboot. Seems to be the solution to every problem with that sensor.

I admit this is sometimes frustrating for me too. I'm curious as to a quick fix.

Proximity sensor and phonecalls.

Why when I press dial the screen turns off right away? The screen should only turn off when I put it next to my ear. It's very annoying when I'm dialing automated systems and need to use the keypad because if I manually turn the screen back on and then put it next to my ear to talk the screen doesn't turn off and I end up accidentally pushing buttons.
On an iphone the screen remains on and only turns of when put next to my ear, and turns right back on when pulled away from an ear. Is there a way to duplicate this behavior on GS4?

Go to settings/My device/call settings and select turn off screen during calls. That should do it.

Thanks, the screen doesn't turn off anymore but it also stays on when I put it next to my ear... I don't get why Samsung can't get a basic function like that right.

In your original post you forgot to let us know what exact rom you are using.
It would be very helpful to know that and other specifics before offering any suggestions.
Good luck!

Well, I tried this on a stock rom with the same result. Are you saying it works for you?

Download an app from the android market (its free) called AndroSensor and see if that app is saying the proximity sensor is blocked. You might have a spec of dirt causing it to always return that its blocked. Read other threads with same issue, and in the one thread, the guy at T-Mobile took a can of compressed air and blasted out the earpiece and it fixed it.

I downloaded the app and proximity sensor does not show any reading all the other functions have a graph next to them but not the sensor. Does this mean it's broken? And if it is broken does tmobile exchange the phone or do I have to send it back to Samsung?

It's definitely a hardware issue which should be covered. You just gotta make sure you get it back to stock and reset your counter with triangle away.

Agreed. Definitely hardware. Your sensor is reporting that the sensor is never covered and always open. Use that app and a test call to show the Rep at T-Mobile.

Proximity sensor not working right in calls

In most KK ROMs I've tried, the screen immediately goes off during calls, even if phone is not against my ear, and will not come on unless I press Home or Power several times.
Is there any fix for this??

Anyone? Bump?

Check under the phone settings for proximity settings. It should be under the settings in the phone app. Haven't used cm in a while, but it was located there at one time.

Proximity sensor

So I have the survivor case by griffin technology and it seems to block the sensor. Every time I need to make a call or answer a call I have to take the top portion off to answer or hang up the call. Is there an app to disable the sensron

Open your dialer and push menu and go to call settings. Disable turn off screen during calls. It will keep the screen on so you can make our hang up calls manually.

Try darkening the area around the opening to the proximity sensor.
## Found this in android forums ##
Alister, what is the color(s) of your Otterbox? Mine is the grey/white, and I solved my prob, just like yours, by darkening the area just above the proximity sensor with a fine-tipped black Magic Marker pen. Additionally, you can get an app that tests all of your S4's sensors, including the proximity. Mine is called Z-Device test, and works great. Get back..

For reference to anyone else finding this thread, this will only work on TouchWiz roms. AOSP rom's typicaly don't have the option to disable the proximity sensor.

I don't have that option in the settings of CM11. In my case I can't get the screen to come BACK ON during a call when I pull it from my face. So much for using the dialpad during an automated menu call..

My apologies! I didn't realize you were using CM. Its been a long time since I used it so I'm no longer familiar with it.

You can cut out or drill the case where it overhangs the sensor.
