Sony Xperia SP - Screen won't light up during calls!

[ehrimen]

I can make calls and receive calls but when I call someone the screen goes black and it's not lighting up again, except the other person hangs up the phone. I've tried to go back to factory settings but it still the same.

Btw, I have no cover or screen protector.

The screen lock doesn't cause any problem when i try this here so this sounds more like a problem with the proximity sensor in your phone.

First make sure that you don't have any cover or screen protector that's covering it. I also recommend that you try making a repair of the phones software using Update Service: http://www.sonymobile.com/global-en/tools/update%20service/.

If that doesn't help i suggest that you contact a service location or local Sony Xperia support (http://www.sonymobile.com/global-en/support/contact-us/) for assistance.

I also have this problem recently, and I this won't happen in the past 5 month when I dialog to somebodies...

I also had the same problem. When I call someone, my xperia SP screen goes black and I cannot light up my screen unless the person in the other end ends the call. This only happens when I call from outdoor not while I call from my room or some places where there is less light (comparatively).  I have screen protector in my device. However,I found out that whenever my screen goes black, I just clicked the power button twice and I was able to light up my screen even while I call from outdoor. So to those who are having this problem try clicking power button twice. For those whose have checked the "Power button ends call", first uncheck that option and try method as described above. Hope this helps.

I have exact same problem, sometimes this bug affects my screen during call. I suspect that it is related to 

- Settings > Display > Sleep  > After 1 minute of inactivity

- Settings > Security > Automatically lock > Immediatly after sleep

Agree with http://talk.sonymobile.com/t5/user/viewprofilepage/user-id/84989

Do not have screen protector. Please fix it.

Even I am facing the same problem. Quite irritating. It has started after update. Before this it was working fine. Any solution, need urgently....

It's clearly a software issue as I got this problem after update. Pl suggest some way out or release software patch to fix this problem.

Did you tired the method I described above?? Another thing you can do is increase the brightness through settings and see if that helps. I worked for me.

Unfortunately, the Update Service software does NOT include Xperia SP in its list of phones...

The only thing that works so far is pressing the power button twice when the screen goes of when making or receiving calls...

This is a clearly a bug, perhaps due to the Android 4.3 release for the Xperia SP.

If it won't gets fixed soon by SONY (I already went to the service for OTHER issue and got my device replaced, and I'm not willing to stay again without a phone for days to check this thing too) guess what my next brand of phone will be. Yep. NOT SONY.
