Screen flick problem with Z2

[Pawan72]

Hi,

I bought my Z2 just 2 weeks back and since then the screen flick when coming back to home screen or click the home button while home screen itself.  Screen goes black either on left or right side (vertically about 1 inch wide black strip from top to bottom) for a couple of movements and then comes back to normal.  It happens everytime move on to home screen.   As a lay man I can say seems issue with software or memore management.  Please assist..

thanks

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Do you experience the same behaviour if you boot your phone into safe mode?

If yes, I suggest that you perform a software repair via PC Companion to exclude software related problems:

http://www.sonymobile.com/global-en/tools/pc-companion/

In PC Companion you press start on Support Zone > Start on Update the phone/tablet software > Repair phone/tablet (the blue clickable link in the message) > Follow these steps without having your device connected to the PC.

Follow the instruction that appears in the program and do not connect your device until this guide tells you how to connect it.
