My samsung Galaxy TabS keeps shutting down and restarting again by itself! the screen stops working first and multiple black transverse lines shown the the device restart alone by itself any suggestions or opinions please ?
Sounds like your tablet is stuck in a boot loop. Samsung phones and tablets have bad power buttons and when they get stuck or brake they often do this loop. You can try tapping the power on button for a while or tapping the side of the phone gently on a soft surface to jar the stuck button free. You can also try blowing a gush of compressed air at it .Hope this helps
