If you remember v 8.12 repaired a bug where auto brightness was always on. Being grateful for that, because it was the only thing that kept me undecided for keeping the watch.
But... What I experienced with 8.12 and now with 9.17 is that the problem is sorta half baked. What I notice is that setting the custom brightness works ok, when I flip the wrist it display directly at desired level without the fade-in transition, but if I am in a bright environment like direct sunlight and I was setting, let's say, at 30% it automaticlly raise the brightness by itself, despite it is in manual mode. Than, after there is no more in direct light. it goes back 30%.
Do you notice a similar behaviour?
