I have an Apple Watch Series 6 (Model: M00H3LL/A) that was working perfectly before I updated it to watchOS 26.0 beta on 21st August 2024. The update process completed smoothly while the watch was on the charger, but immediately after the update the display became extremely dim.
It’s not completely black, but so faint that it’s very difficult to see. I’ve already tried setting the brightness to maximum and also enabled maximum brightness under Accessibility settings, but the issue remains. I also tried force restarting the watch (holding the Digital Crown and side button together), but that did not resolve the issue.
I know this is not a hardware issue, since the problem appeared immediately after the update, and at times the display briefly returns to normal brightness for just a few milliseconds (like a flicker).
My current watchOS version is 26.0 (23R5350a). Could you please advise on how I can fix this, or confirm if this is a known issue with the beta version?
Thank you.
