I've got an s6 lite (first release) too. I mainly use it for drawing. Infinite Painter is great, and Krita is really powerful as long as you keep the canvas size reasonable.
Minecraft if the kids are about. Battlefield 2042 if they're not.
I've always found chess enjoyable to play but tiring, as it requires a lot of thinking. I also used to get frustrated by waiting for the other person to make their move, whilst they think out the options... I've recently started to play games using a chess timer on my phone, set to 10 minutes each. Makes it a lot more enjoyable for me. I'm really enjoying chess again.
I haven't found any r/drawing or r/sketchaday type communities yet...
Jerboa on Android seems pretty easy to use so far.
Boo... Sync has been my go-to for ten years...
Yes. I actively avoided that sub. A Melbourne DT equivalent would be great too.
