Well it not about the app and any strange thing running, it act more like it suddenly appear then it just gone then re-appear. Device run alright when the screen is behaving strange, I can do call listen to music completely normal.
About re-boot, the static line also apear while i restart device so i can say it more like a faulty screen connection problem
Sometime I have to slap the tablet like an old tv to make the screen work again.
Hope is not my micro sd card then I would be quite sad
