Oh holy shit. I've done that a few times. Completely using GPS by audio and without thinking I put the phone down in the Sun. I've never done it more than 10 or 15 minutes before I remembered and every time it would be so fucking hot. Even with the screen off and everything which really should have helped keep it cool you know?

The big problem here I was an instacart driver at the time so I had all these fucking weird things I had to do with my phone to make sure it didn't explode while I was trying to keep it charged so I could work all day.
