Has anyone encountered this issue? My S4 restarts for no reason... It restarts while still restarting. I've had it for a week and am going this morning to the shop to get a replacement. I phoned Samsung support and first thing they said was absoluttely nothing was wrong with the new S4. Obviously that conversation did not go well... I also had battery problems and Samsung account problems but a factory reset and a new account fixed that. Probably due to the constant restarts, the screen has begun to show very thin white stripes.... Should i get a new S4 or get someother Smartphone? Its a shame because i saved like crazy to get my first Smartphone and it turned out like this...
