Xperia II, during phone calls, the screen turns black and I can hardly use any of the buttons

Applications

Whenever I make or get a call, the phone goes to black and the buttons stop working.
Any button press turns the screen on for half a second until it turns to black again.
Continuing to press audio buttons randomly breaks the spell.

Looks your proximity sensor has some issues. First Iā€™d test it. Open settings->About->touch fastly 3 times on Version.

It will open the CSD Tool. Accept, choose individual test and Proximity sensor.

ā€˜Aboutā€™ is the ā€œiā€ in square with ā€˜About the deviceā€™ right?
Tapping three times does nothing.

  • Open Settings
  • Open About Devices
  • Touch 3 times on Version.

Ah, I donā€™t know why I read that as ā€˜to turn on Versionā€™.

Itā€™s test procedure tells me I need to
cover and uncover the proximity sensor three times.
How do I do that?

[edit]
My proximity sensor seems to be very unresponsive.
I need to press very hard to get anything.
The glass on my phone is cracked, so Iā€™ll bring it to the repair shop.

  1. Put your phone on a plane surface, start the test.
  2. Hold your hand over the phone and move it closer until the phone detects your hand.
  3. Repeat last action 2 or 3 times
