Screen goes black during call

[magamra]

Hello, if I want to make the Z5 a call and dial the number and pick up the phone, the screen goes black and I can do nothing more. It then responds to anything, not even on the Power button until the other ends the call. Then, the screen lights up again and it goes back all normal.

Hallo, wenn ich mit dem Z5 einen Anruf machen möchte und die Nummer wähle und den Hörer abnehme, wird der Bildschirm schwarz und ich kann nichts mehr machen. Es reagiert dann auf nichts, nicht mal auf die Power Taste bis der andere das Gespräch beendet. Dann wird der Bildschirm wieder **bleep** und es geht wieder alles normal.

HI, there is a workaround in the settings I believe. You can set the phone call to end by pressing the screen unlock key. Though if you need dial pad during call you're out of luck. I have this same problem and my SO'S Z5 compact has become unusable after nougat. There are too many bugs out there and the battery drain is huge on both phones.

I'm somewhat grateful that Sony offers these updates for free, but if the end result is this bad I'd rather not take these updates.

Been haing this issue for a little whiel.  When making a call, or receiving a call; as soon as it is connected the screen goes black. I seem unable to get the screen to wake up, so if I need to input any numbers (for example for in call menus) I am unable to do this.  Or even end the call.  I have tried software resets, going through the engineers menu, diagnistics.  Nothing.  I have switched the accessibilty to allow me to end the calls with the power button, but this is making the phone pain.   have sent it off for repairs, which worked for about 5 days, then back to the same old problem.  I do not have a screen protector on it, I have tried in SAFE mode, and still the ame issue.  Not sure if anyone can help, but if you don't ask you don't get.

Regards

You can press firmly in the upper right corner of your screen to get the screen back during a call. You may have to hold that pressure.

Not a fix, but a workaround. It's annoying. For me, it's an intermittant  problem. So far.

Hi,

I have  this problem also.  

My screen had smashed up so I had to give my phone  to technical service. They replaced the screen with the new one. 

I am not sure if this problem  occured due to replacement  of new screen.

Hi people bought a z5 compact and discovered had a faulty proximity sensor as it constantly on.

The screen had lifted on the proximity sensor corner of phone. Used hair dryer to push back down did service test still on constant is it an expensive fix????

Whenever I try to call someone or if someone calls me my display turns black and i can do noting until the one who called me finished the call. The diagnosis from the phone is that the sensor is broken ... but what should i do now ? How can i repair the sensor or can sony repair the sensor ? Or do i have to buy a new phone ?

@Andimacht

Do you have a screen protector installed?

Hey there

I upgraded my Xperia z5 premium dual to Android 7.1, and just I wondering that cause problems!

For upgrading to Android 7.0, I have cooler phone, better battery usage, and no lag and bug during using.

But now, I have problems with battery draining, heating, and a phone stopping and bothering me.

I repair with Xperia companion, and then reset again but in calling process:

Screen goes off and lock key doesn't work, I need to press it again and again to see whom calling me. After answering

Many days ago  I updated my phone after that when I call someone my phones screen be black and I can't see any thing during calling 

What do I do?
