Screen goes off when making call

[sarathraj222]

Whenever I make calls on my Xperia C4 the screen goes off and can't be restored. To get the display back I should either remove the sim card to restart the phone or connect a charger. What should I do with this..? Please help me....

Hi!

I suggest that you test your phone's proximity sensor in Diagnostics, Settings > About phone > Diagnostics > Test > Ear proximity. When you test it the phone should only vibrate when you place it with the screen facing down and the proximity sensor is covered.

Thanks for the suggestion.....
The proximity sensor was not working perfectly....
So I tried to remove the tinted glass screen guard on my phone...
Now its working perfectly...
