I used the Moto G4 Plus camera outdoors and after extended constant usage in direct sunlight on a hot day, it starts to lag and sometimes won't even take a picture in 15-30 seconds, and sometimes it won't take a picture at all. I tried to force close and it still won't take pictures. Tried to restart the phone and it didn't work. I let it cool down for a fee minutes and it works again like normal.
I have also had issue of the camera app closing on its own.
