The update from Android 10 to Android 11 went OK for me. It seems more responsive, but I could be wrong.
Unfortunatelly after update some of the keys on the physical keyboard make problems, when pressed display 2 characters:
press 2 → 12 is displayed
press w → ew is displayed
press s → as is displayed
press x → zx as is displayed
If I press the OSD keyboard, characters are displayed correctly.
I did not notice this problem with Android 10(I could be wrong), and I simply cannot beleive that a brand new physical keyboard was shipped like this or it stopped working in less than 2 hours of use.
I have the tablet for less than 2 weeks, and used it mainly without keyboard.
