What do you mean? While you answer calls, the screen does not off?

[Moheb]

yes   exactly

Try to take a look on the top area of the phone. Make sure is clean even with screen protector or not.

Some times face oil may also effect that, if after cleaning still don't work.

You may try to perform a factory data reset and do remember to backup your phone before reset.

Please keep us update if this resolve your issue.

what about i dailed *#*#7378423#*#* >service tests > proximity switch > it shows proximity switch off

From my understanding, by default that should not be off and you cannot switch it off unless you root the device.

To avoid any software screwed up on your phone, try to do a factory data reset to see if that works.

Sorry to hear this but you would need to either return your device to the place of purchase or contact Xperia care and have your device inspected http://www.sonymobile.com/global-en/support/contact-us/

Proximity switch "off" in service menu does not mean that the sensor is turned off completly, it only means that the sensor is currently in "off" state, meaning that nothing is currenty triggering the sensor (such as your ear ).

However, if something is wrong with the sensor it will always be set to "off".

I guess you have tried rebooting the phone? Sometimes the sensors hang and a reboot might help.

Don't press "restart" key, turn the phone off and then on again.

Do you have Lollipop or Kitkat in your phone?
