Okay so just after flashing a backup my phone booted and i noticed some lag. So off to twrp to wipe davlic. As i watched the screen shut off i picked my phone back up in anticipation of recovery. This is where I noticed it. It was so hot i thought it might burn my flesh. So.. i needed to know. I rebooted and held it.. it got hot again. Real hot. So i (fearing the death of my phone every second) went to the playstore downloaded a cpu temp app. It was at 41 Celsius. Ambient was 65-70 degrees Fahrenheit. I immediately wiped completely and flashed a different rom. Now its not so bad.. but it does still hit 38-40 sometimes.
