Can the brightness issue be resolved through a factory reset on Apple Watch Ultra 2

Several users have reported that even after resetting their watches, the auto-dimming feature still limits the screen brightness to an unusable level in dark environments, despite the brightness being set to maximum[1][2][3]. Disabling night mode seems to provide some improvement, but the screen still dims excessively[2].

The core problem stems from the automatic brightness adjustment controlled by the watch's ambient light sensor. This sensor is designed to reduce the display brightness in low-light conditions to conserve battery life, but many users find that it dims the screen too much, making it difficult to read even basic information[1][3][6].

Attempts to manually override the auto-brightness setting by turning it off have also proven ineffective, as the watch then locks the brightness to match the current ambient light conditions[1][7]. This behavior suggests a software limitation rather than a hardware issue.

While a factory reset may resolve some isolated software glitches, it is not expected to fix the core problem of the auto-dimming feature being too aggressive in low-light situations. Users have reported that this issue persists across multiple watch units, indicating a widespread software-related problem that requires an update from Apple to address[3][8].
