Mi6 - Miui 10.2 - 8.11.1
I have already put these in the bug section, but it is still happening:
One-handed mode
After a reboot, the setting still says that it is on, but it does not work. To get it working again, you have to turn it off, then on again.
Also the movie graphic is at high speed.,
Automatic brightness
Again, after a reboot, it does not hold its setting. The brightness adjusts itself to minimum, so it has to be re-adjusted back to the level it was at.
Mail received
It has been doing a double play of the notification sound when email is received, and it also plays the notification for each email. A little embarrassing if you receive, say, 10 emails. This plays your notification 20 times! I cannot find a way to control it. It happened with K-9, and it is also happening with Blue Mail.
