ones so far:

1. apps are rather slow to install, since GOS compiles JIT (just-in-time compiled code) on install for security/speed. It's a bit of a pain when I'm needing something now 2. play integrity fails, so some banks¹ don't work, and NFC payments are pretty much bricked 3. I had some weird issue setting up my galaxy watch. probably a Samsung thing but it'd download software for an hour then fail with a generic message multiple times

now writing this out, I realize a lot of these are skill issues I need to just take a couple hours and try to fix

1: my solution is just to use web apps and it works well since I end up with less apps. PWA FTW!
