Phone Gets hot when reading maps

I read that there are still problems with a too warm fp4. Alsof with my Fp4. It happens after long use or when using when following a road with Google maps of Waze. What causes this and can it be solved?

The phone getting hot when running GPS navigation is pretty normal in my opinion. Especially if you are also charging the phone at the same time. All my phones did that. :man_shrugging: But other than that, my FP4 pretty much only heats up when playing games for a long time.
