S8 Heats up when watching camera

When I watch a camera my smartphone gets very hot. Especially, when it’s on a wireless charger. It will cut off charging due to heat. Even when not charging it heats up drastically, not to the point of shutting down or locking up.

I have other apps for other cameras and I can leave them on constantly without any issues but the eufy app, while viewing cameras, really is worrisome. I would use it more but this issue could eventually kill my phone.

Any ideas on how to cure this problem?
