well, this smartphone was working well, no damages, like in the drawer. Suddenly, 2 weeks ago, it became to give me white screen sometimes, and touch screen sometimes refused to work,but I made it in stand by and ok, 3 days ago I now have white screen from the fisrt start without logo, though telephone is booting, I can call, bt white screen is always, whe i open the keyboard, i see black switched off screen, when move to close the keyboard, again white screen. What the deal guys, it is not general situation, I have past ove 8 sites before writing this to you here. I need to know the problem, what is the problem here? is that the flat cable problem or is that screen problem? I wait, thanks.
