Screen goes black while in call - Sony Xperia XZ2 Compact Questions & Answers

Hi,anyone have this issue in the moment when start ringing on the other side,screen goes black i can wake it up only by double pressing the camera key,i read that this is common issue with xz2 phones someone has report that changing the stock dialer is making this problem goes away but not in my case,i check sensors in diagnostic menu phone says diagnostic is ok,im not using any screen protectors or covers and nothing is covering the sensors,i did full factory reset and having the same problem again,i dont have a warranty on it so any susggestion would be great.

It happened to me before once ot twice too. I think it is tied to a problem with touch while receiving calls that has it's own discussion on the Sony forums. I captured a screenshot of the problem occuring. (touch was not working until i restarted the screen)

No,the problem is happening only when im making calls,reciveing call are fine

Nevermind then

Hello,
I have the same issue, during a call the screen sometimes goes black like it was locked but then it lights up when I presse the ower button twice. That's strange but I think this is a software problem, since everything else is working well.

Basic function doesent work calling,no words

Manila Spaz Out! (Pictures and Videos) Does this happen to anyone else?

I experience this from time to time since my recent software reset. Didn't happen much in the beginning, but I'm sure it must of been something I installed and uninstalled of a program I tried out. Could be Batti causing the problems, as it seems to have come about when I started using Batti.
There would be junk at the top, as well as almost all hardware buttons don't work. Some soft buttons may work, but don't do much. Blank Menus occur. Start button doesn't work, so I can't get to settings to manually deactivate Manila. Manila may restart on it's own, but no resolution and bugs still occur. Power button doesn't work, so I gotta open the battery case and soft reset.
Does this happen to anyone else (particularly Sprint users)? Are you also using Batti?
Here are pictures and Video

I have, for a very short while, used Batti with no problems at all. Maybe another piece of software you've installed??
If this problem persists, the only way out is to do a hard reset.

Proximity Sensor Issue - Hardware Issue

I have Motorola Defy MB525. A Strange issue surfaced recently. The Proximity sensor is behaving weird - It works sometimes and doesnt sometime!
Sometimes even after the call, the red color sensor keeps lit until I pass my finger over it to close.
As soon as I make a call, the display turns off completely and I am left with no option to turn the screen ON to disconnect the call or do any other task. The moment the call gets disconnected, the light turn ON back.
The situation is weird and I am sure its something related with hardware as I tried various other ROM and its the same result in each ROM!
What I need to ask is, whether there is any method to turn off the sensor completely? Or I should just smash that sensor to make it go die and non-functional?
The sensor is attached to motherboard and not a separate hardware at motherboard unlike camera and other stuffs.
Any suggestions or ideas to overcome this strange issue?

There are some reports that turning the screw behind the Proximity sensor half a turn would fix the problem.

Reaplaced screen, now its turning white.

Hey, so i replaced my screen the other day and it worked fine until today when it suddenly started turning white. When i turn the screen on my it looks completely fine, after about 5 seconds a white shadow starts to appear in the background and slowly starts to make certain parts of my screen white. I opened the phone again and looked at all the cables to see if something was loose, but did not see anything wrong. Do any of you know what could be wrong?

Before you replace the screen the phone was normal? It can be LCD itself, someone with more accurate knowledge can help you with this. Better luck!

Yeah, well the screen was shattered but not white. I put on a screen protector and maybe pressed to hard... :/? and suddenly there was some white lines that got worse and worse kind of similar to this guy https://www.youtube.com/watch?v=DI64Bcf8OiE

Youtube problem

Hello, sometimes when I swipe down a video it doesn't work. Another problem are the buttons which aren't at their place. I made 2 screenshots where you can see exactly the problems. The phone I'm using is an HTC 10 with Android Oreo, latest patches. Does anybody know a solution or could google launch a update? Is anyone having the same problem?

Yes, same issue here.
- Somtimes buttons don't want to disappear
- Exiting full screen by pressing back button leaves a big grey part in the app
Going back to the stock youtube app fixes it, so... a bug in the youtube app?
Same problem.
Same problem too....
Hello. Im experiencing same problem. I have gone back to youtube stock but the problem is still there.
Same problem here. Also when I turn the phone sideways it doesn't always show the full length scrub bar. It ends up in the top left corner. Still using the stock app, but Youtube bugs me to update it now.

Question Front Screen No Longer Working

Hello All,
As the title says, the front scree is no longer working. When I perform a reboot, the screen does show some pink/blue static on the front screen, then turns black when the phone completes the reboot. The always on display sometimes comes on, but very rarely. It sounds like the phone is still working with the black screen (I can hear the unlock sound when I use my finger on the fingerprint reader). Is anyone else experiencing this? Any ideas on what I can do to troubleshoot this? I have tried a factory reset with no luck. Picture of screen during the reboot is attached (black lines on screen are a reflection).
Thanks.

Looks like hardware. Maybe a loose connector or failed hinge flex cable.
Looks like you need to call Sammy and see if you can get them to cover it, otherwise, you're going to end up paying for a replacement/new phone.
I had this problem with an older Sam phone. The screen would come on and then fade away. I found if I wound the brighness up full immediately after boot and before it faded away it would stay on. If I turned the brightness down it locked off again and had to be rebooted.
It's still OK as a spare phone provided I don't touch the brightness
Take it to a Samsung Service Center for repairs
