I don't know what this is, I never had this problem before with any phone. Please help me. Also I have the international version, the GT- I9300. And the lines and dots aren't visible normally, the phone works just fine You can't even see those 'things' normally when the phone is on.
Sent from my GT-I9300 using xda app-developers app
try flashing another rom and another recovery, like phil'z recovery. if the problem persists, it's probably the screen.
Don't forget to press the "Thanks" button if i helped you!
