I downloaded an app which recalibrates the settings on the proximity sensor and it resolved the issue for me. Good luck.

Re: Xperia Z - Screen going completely blank during call

Have the same problem on my Z5.

Has been on repair 3 times now which equals more than month in total.

No one seems to be able to fix it! Sony provides no help.

Re: Xperia Z - Screen going completely blank during call

I had the same problem with my new Z5, I did a software reload and although it hasn't cured the problem completely, it's helped. I talked to Sony technical and they said that it might be problems with the proximity switch. I went through the test procedure and the proximity switch didn't work - it was showing permanently on but doing nothing. After the software reload it does. Here's how to test it - from the Phone [call] screen type  *#*#7378423#*#* and then select Service Tests and then select Proximity Switch. The screen should show it 'off'
When you move your hand over the top of the display, the device should detect this, the screen shows 'on' and vibrates. It should vibrate until your hand has moved away from the handset.

 

 

cheers

Exact same issue on my Z5. The screen protector started to lift in the top right corner and some dirt got under it. Removed the screen protector and problem resolved!

Re: Xperia Z - Screen going completely blank during call

Same thing happens to me. Initially it was a screen protector, but apparently even th slightest smudge can trigger this problem. Since I keep my phone in a protective hard case that doesnt cover the camera this issue is made even worse since the ONLY way to resolve is to take the case apart and clean with sterile wipes and even then it's only resolved temporarily and there's no warning before it happens again.

 

If i double tap the power button the camera app opens on the screen, but switching to the phone app to try to either hang up or go into speaker mode makes it go black again.

Between the power bugs with the Z2 tablet and the new bugs with the Z5 premium Im thinking the only good sony mobile device was the z1 tablet and Im probably going to avoid importing sony phones in the future. It's obviously simple firmware issues that can be fixed, but instead of actually fixing these issues they just put all their effort into the next device.

Re: Xperia Z - Screen going completely blank during call

Thanks for that. My screen has a small crack just at that point.... by just touching it I can now see the screen whilst calling. It was driving me bonkers.

I had this problem and it's nothing to do with software or apps as I followed advice on forum. It's the screen protector that covers the sensor. On the phone to the right of the Sony logo is an oblong and circle shape. If those are exposed it should resolve the problem as it has for me. I have just cut out that bit of the screen protector now. I was ready to send the phone back


Thanks

Re: Xperia Z - Screen going completely blank during call

I've the same problem on-going for a couple of months.  I don't have a screen protector as thought that this was the cause.  

 

Today I did a factory reset and it seems to have cured the problem.

Dear friends me also faced similar problem when I calling time display light is not working but I find out a solution go to settings - about phone - diagonostic option select- test option -select Ear proximity option and keep ur phone near to year in flat if it vibrating it will work or keep ur in flat place like floor and take it back.
