Hi !

Just got my 16 Pro Max, brand new. After that i started building a stone oven in my backyard. Temperature outside was 70F with some wind. My phone was sitting on the bench.
After one hour i checked the phone and the display was green with black artefacts and it phone was hot as hell. Took it inside and after maybe 30 seconds everything was back to normal.

Did the display glitch ? GPU ? Perhaps the display cable had a bad connection due to the phone being hot ?

After the event i tested the phone to check for permanent damage.. did a Geekbench score, performance is unaffected and doesnt get hot, checked the display colors with some apps and it looks good. Brightness is solid.

I own iPhones since 2007, previous phone was 15 Pro Max.. this never happend to me.

Should i return it and get another one ?
 
Direct sunlight to an electronic device with a glass screen = hot and will overheat easy, especially sitting out in the sun. Gotta have some basic common sense. Same reasoning a magnifying glass can burn plants and insects directing sunlight.
 
Most people know that you can not leave your phone in direct sun. It did not glitch, it was just overheated.
 
Looks like your phone just got too hot in the sun and had a little display hiccup. If it only happened once and everything’s back to normal, I’d just try not to leave it baking in direct sunlight.
 
While I can't see myself ever leaving my phone in direct sun for more than a couple minutes, I'm now wondering how the Apple Watch has been designed for the inevitable longer exposure to heat from the sun.

The Apple Watch and iPhone both list identical operating temperature ranges (32°-95°F / 0°-35°C). However, your wrist will act as a heat sink for the watch, and it's also usually moving around from full sun to partially/fully shaded while you're wearing it. The watch face also has quite a bit less surface area than the phone, so it will absorb less of the energy from the sunlight.

I've worn my watch for long hours in temperatures well over 100°F and prolonged exposure to sunlight and never had a problem, but in that kind of heat my phone will overheat and shut down within less than 5 minutes if I leave it in the sun. If you were to take the watch off and set it in full sunlight on a warm day I'm sure it would overheat also - probably not as quickly as the phone, but eventually.

OP's phone just overheated, and once it got back to safe operating temps it resumed normal operation. No harm done.

I have left all of my phones in the sun since 2004 when i got my first phone and this 16PM was the only one with issues.

Common sense ? Bro, i owned cellphones for over 2 decades and this is the first time a product fails in the sun :)
 
Devices always behave strangely when they’ve overheated & throttled. I wouldn’t worry about it as Apple have implemented safety features to prevent damage to the circuitry.
