My favorite apps were working fine on 2.1.2 but many issues came with 2.2.2 I spent a fair bit amount of time fixing those issues, so here are all my fixes in case it helps anyone else:
First general tip: disable âwhiten backgroundâ in the app optimization settings (navigation ball > settings) this fixes various issues.
Second general tip, for Note 1 only: add a âfull screenâ button to your navigation ball, and use it to make the taskbar appear again when it becomes unvisible for some apps.
Those two tips are enough to fix Youtube and VLC but not Slack.
Slack specific fixes: disable âembolden fontâ and decrease DPI to 290 or so. Slack becomes great again!
