Issue started a few days ago, whenever the screen goes off while the WIFI is on the phone reboots. Once it reboots, if I don't switch WIFI off the phone keeps rebooting and warms up. While the screen is on, the phone works great, no issues at all. When the screen goes off, it reboots.
What I've tried so far:
Boot into safe mode, same issue
Repair with SUS, same issue
Downgrade to stock 4.1, same issue
Upgrade to different stock 4.3, same issue
Is anyone else seeing this? Any ideas for a workaround?
