@lakotaubp , thank you for the quick answers.
The function keys I'm actually not that worried about because those will trigger normal F1 to F12 keystrokes.
I had a quick look at the other projects and seems that latest status is based on Android 11.
At this moment our units are based on Android 12L.
Knowing the relative short life cycle of Qualcomm processors and updates, I wonder a bit how much lifetime would be left when starting such an endeavor.
There are also some concerns about liability, certifications and other topics which would be important as soon as you would provide such devices with UB pre-loaded.
So I think I will pick up on your offer an PM you next week or so.
I think UB is a wonderful project especially for industrial based devices!
Thank you in advance!
