I have Samsung Galaxy X phone, model number GT-S5690. This is my first Android phone and I’m having some problems with it. I have installed a bunch of apps and everything seemed fine until I installed Angry Birds. When I start up the game the screen starts flickering, right from the beginning when the splash screen (Rovio) shows up. Well, I figured it might be a bug so I installed the newest firmware, but that didn’t help. Then I tried installing another game (Angry Birds Rio) but that one flickered too and the next one I installed had the same problem (Fruit Ninja). The flickering looks like black triangles or lines flashing over the screen. Do I have a defect phone or is there some magic update or software I’m not aware of? Why am I getting screen flicker problem while playing games in my Samsung galaxy Xcover?
