Dear Garmin,
The Fenix 8 43mm AMOLED is extremely hard to read in dark rooms and/or at night due to the adaptive brightness. That "feature" dims the display in dark environments to the point where older eyes can't read it. In brighter environments it is easy to read, and I can readily reproduce the problem if I turn the display on while my hand is covering the watch. It is absolutely the light sensor that's driving this behavior.
This is NOT an issue with my brightness setting, that's already set to maximum.
This is NOT an issue with night/sleep mode, the problem exists during the day.
This is NOT a problem with my watch face, I'm using one of the default faces.
This IS a problem with the firmware and the fact that there is no way to disable adaptive brightness. This oversight (or terrible design choice) is ruining an otherwise great watch for many of us.
Fix it.
