Hey,
I have just hard resetted my unit and installed about 20 Programs containing all important stuff. Now I have some problems with my graphics. Just look the screenshots I added and dont care about the language :).
My second problem is the switch bar. I have opened up many programs, but switchbar dont shows them everytime. Please look 2nd Screenshot.
Both problems just can be solved by softresetting the unit.
What do you think is the problem?
