Count me in too. I'm at a school filming my daughter's first show choir solo and the screen starts stuttering. Soon after that, I get the temperature warning and shut down. I left Apple for this? Really?
I had the same issue today just shooting photos on auto mode. The phone got very hot and the camera continuously shut down with a message that it was overheated. I had to turn off the phone twice. What is going on? I did not have this problem with the note8 but I went through 3 note 7s so I am very concerned.
I have also been experiencing the Samsung Note 9 camera shutting down due to overheating issues both in Orlando, Florida and here in Phoenix. Neither time was an especially hot day and I had quit all extra apps. Made it hard to get pictures that were time sensitive since it wouldn't cool down in time. Very annoying and now I fear it will do the same at any time. Mine is a 128gb model.
