So far, the only thing I know for sure that I would consider using it for is to use JoiPlay to play RPG Maker games that I can’t get working with my normal methods but at least on my current computer/distro, I’m having issues with audio crackling.
I might find other apps to use later but for the most part, I just kind of keep android apps to android.
On Linux, I’m using Firefox as my main browser and Vivaldi as my secondary browser.
On android, some of my devices have Firefox, some of them have Fennec F-Droid and the devices that don’t have very much storage space have Via Browser. If you’re wondering why I have both Firefox and F-Droid’s Fennec, it’s because I used to just use Fennec but then at some point F-Droid announced that Fennec was outdated and it was missing several security updates that were present in Firefox. I switched to Firefox on the devices I use browsers on more actively but I didn’t see a reason to switch all of them.
