My Fenix 8 AMOLED 47mm consistently crashes when the water temperature drops below 8°C.
This is a significant issue where I live, as the water temperature often falls below that.
Interestingly, after a crash due to the temperature drop, the watch can usually reboot and function properly, even if the displayed temperature is below 8°C.
In Europe, dive instruments must be tested down to 0°C to be on the market, so I find it surprising for a watch advertised to operate in negative temperatures to have this problem.
I've noticed other users reporting the same issue on Reddit.
I'm wondering if this is a software safety feature that might be resolved in an update, or if I should consider sending the watch back.
It seems the watch can operate in low temperatures, but the sudden temperature drop when entering the water causes it to crash consistently.
