I have been having issues with my Samsung S2X for the past few weeks, seemingly out of nowhere. 1) I first noticed that the screen would flicker when I scroll down certain applications like Instagram 2) Now every time I press "home" button only the background appears on the phone and then it blinks a few times, seemingly to refresh itself before the widgets show up 3) The phone would freeze randomly 4) Certain text messages don't get sent What should I do? This certainly seems like a global issue with the phone. Maybe it's contracted a virus? I have an Antivirus app however, so unlikely?
