croc is great, works even when devices cant find each other on the network, or with gigantic folders (I use it between computers).

Or Simplex chat, I dont use it to chat but only to quickly share between phone and laptop :)

A lazy option to set up a player (what I do a t least), is installing via flatpak Jellyfin Media Player. For android, installing from F-droid.

Hey, at least installing a foss browser won’t slow down your phone like a spyware app, you could always try something like Mull even for only a portion of your browsing if you have ~80MB to spare. I suggest it because I hate some of that extra bullshit that comes with standard Firefox. Also there’s tons of projects that try similar stuff with Chromium! Like Mulch. Way better defaults than Chrome
