Hi everyone I have a Samsung galaxy s4 i9505, yesterday my phone ran out of charge so I attached my charger and left it a while and tried turning it on but it just vibrates as if its about to boot up but I'm only left with a black screen. I tried it again today and managed to get it to boot up, it installed an update and rebooted but same problem its back to square one black screen and just vibrates when I try turning it on. Any help would be great, thank you.
