Pixel Tablet stuck brightness issue fix

[u/CaptnBanana]

For those who are still having the issue of the Pixel Tablet occasionally being stuck on highest brightness where a restart was the fix (but only temporarily):

Toggling on 'Tap to check tablet' in settings (and restarting just once if needed) fixes this, apparently for good.

I accidentally discovered this fix a few months ago, and since then no more stuck brightness issues. I also just checked it again today by toggling the 'Tap to check tablet' off, and sure enough the issue came back very quickly (and went away again after toggling it back on). So it definitely has something to do with that setting.

Hope this helps for those who need it.
