Issue has been ongoing for about a week now where my Galaxy S5 will just reboot on it's on and the phone is getting hotter and hotter. I've done at 10 hard factory resets and cleared the cache partition. All to no avail. I ordered a new battery that's coming this week. Is anyone else having this issue? I need answers because I use this phone for work as well and it has rebooted while on the phone. Please help.
