Hello,

i have the problem that, if i start a phone call, sometime my screen gets blank (black) like if i put it on my ear (so i cant use the speaker a.s.o.).

I thought the update would help but today i get the same bug... But i mentioned, that, if i put my device in horizontal position while it is black, the screen re-apears, but if i take it and hold it in my hands (in portrait mode) the screen gets black again...
My rotation settings of the phone app is only portrait mode with activating if i hold it in portrait mode in my hands

Maybe its a rotation problem of the accelerator sensors...

Anyone has the same problem or am i the only one?
