Samsung Galaxy Tab with S-Pen?

Android-family OS for my pen-abled tablet?

I own a Samsung Galaxy Tab S7+ with an S-Pen. I use it to browse the Internet and draw art. My dad uses it as well as a secondary user, though he doesn’t care much for de-googling/de-microsofting/etc. (I tried and failed to convert him to Linux)

I want to continue the process of de-googling.
Now, I want to change the OS on my Samsung Galaxy Tab to an open-source alternative that doesn’t sell your data and stuff. I still would prefer it to be Android-based, and I have the following requirements:

  • Need Discord client and email client
  • Need a lightweight art application (I’m currently using Medibang Paint, so hopefully that’s on F-droid, and I don’t like Krita)
  • Needs to be compatible with the S-Pen, including pressure and palm rejection
  • Allows multiple accounts
  • Allows (optional) Google integration for my dad

Thanks in advance

S-Pen threads seem to fizzle out or go right unanswered. If I’d be you I look for threads with your device in the title and place the question there
