Updated to 10536 2 days ago, from 8.1.2. First tried without a hard reset, but to get rid of loading time after switching on did hard reset. No effect on loading time, still >10 minutes. But after that not many problems, some apps don't update in store, some apps have several seconds resume time, very well usable for daily driver!
Update:
There's no way to control glance, not even via sysapp pusher.
Battery use not stable, sometimes it gets hot, OK after restart.
Data sense does not count my cellular data use, only Wifi.
The loading time after switch on has become much shorter now!
