Hi @Sobaro85,

Welcome to the community. 

The most common reason for this is a screen protector or cover interferring with the proximity sensor. You can test the proximity sensor in Settings > About Phone > Diagnostics > Test > Proximity Sensor. Try this with and without the screen protector.

The problem is the on-screen POWER OFF MESSAGE is coming very soon which make me not able or dont have time to test any thing

@Sobaro85, I'm sorry, I don't quite understand what you mean. The process I posted above should not cause your phone to request that you power off.

Yeah , i know

after doing a factory reset , any Sony device will give a nsg sayin that you have to wait for the POWER OFF key ... so ur phone will bring the word power off to the front of screen and u have no choice but to hit it.

never mind , i solve my problem by third party tool via writing a secrip t to stop factory test in the first bootup after reset.

Thanx.
