Hi everybody. i have problem with my bold 9000; when its screen is darked (the light of screen is off after few seconds) if i press any button to do a call or enter Menu, the screen becomes white and still white till i change it (for example from the main screen to main menu) and sometimes it appears like grains on the screen and sometimes it work normally.i cant understand what's the problem!
i update my mobile os to v5 and after to v4.6 the problem is the same
is there any solution to my pb ? thanks
