Welcome to Android Central! How long has this been going on? Did it start after a recent system update, or perhaps after a particular app was installed? Can you figure out any pattern to when the black screen comes up--like, for example, when waking from sleep, or after running certain apps? Does a reboot usually clear things up?

How long has this been going on?
It has been happening since I bought it 3 months ago

I didn't update the system, and I couldn't detect any relation between this problem and anything else

No there is no relation
Does a reboot usually clear things up?
Maybe temporary

As I mentioned it disappears when I just change the position of the device
I hope I could explain my problem
thanks alot

Maybe it occurred because of overheating
