Phone flickering every 6-7 sec. even after software update and reinstall

Dear All,

Recently I have an unusual experienced with my phone’s screen display. It kept flickering once every 6-7 second. I did updated to the latest software and also did factory reset per advised by tech support but still no luck my phone still keep flickering. So I was wondering what might be problem and what should I do now?

Thanks all,
