Default [Q] Camera App & Battery Issues - GPE

Just wondering if anyone else is having problems with the camera app on the GPE? Mine takes a long time to focus and a full 5 seconds to take an HDR photo (time from when taken until it is rendered). Also I can't swipe to the left when in the app to get to my gallery. Are these known issues?

And I think they're might be a problem with my battery. Sometimes it'll get so hot ~38C and will barely charge when it gets that hot (maybe 10% in 2-3 hours).

Probably should call Google and get a replacement but I wanted to check and see if anyone else is having these issues.

Thanks
