Screen black during calls

[Aals]

Aa soon as I dial a number my screen goes blank. The call is in progress but I am unable to use any function since the screen goes black and blank. At times it gets difficult to disconnect a call also.
It's happens for all voice related functions Eg all types of calls. Listening to a audio clip etc

hi, can you try to replicate the problem while your are on safe mode?

also try to clean your sensors, these are typically found in line with the earpiece. make sure your screen protectors is not blocking the sensors.

Hi @Aals, I am sorry to hear that.

Which phone model do you have? Please note that the Tips & tricks section is not meant for support bur rather sharing knowledge. I have moved your thread temporarily to the Xperia Z2 board, so please let me know which phone model you are using.

As @nolramlb said, there is a proximity sensor located at the top of your Xperia. If this sensor is covered, the screen will go black which helps you during a call. This way, you can avoid accidentally ending calls with your cheek for example. Make sure that you do not have anything obstructing the sensor, for example dirt or a screen protector.

Can you try to see if the same occurs without a screen protector, while the sensor is clean as well as during safe mode?

Let me know how it went!

Thanks for the support.

I indeed use the Sony Z2

There is no screen protector on my screen

The problem persisits even in safe mode

The issue has cropped up only after i upgrade my software to the latest one.

Is the sensor clear of any dirt as well? Make sure that there's no damage done to the display or frame as well.

If it still persists, could you try performing a software repair using Xperia Companion and then report back?
