Auster

Bandcamp, Supraph Online, Ototoy, Uta 573, Steam and GOG’s OSTs and Apple’s iTunes store have been my to-go options. No DRM, no worries. Just avoid Apple’s music subscription, as it is DRM’d.

Never understood why repeating the last word from the top text at the bottom is done in some memes.

On that matter, if you haven’t dug on the topic yet and if I may suggest, look for Linux systems (“distros”) with either the Xfce or Wayland desktop environments, since they’re some of the lightest around (Xfce being the most stable of the two, but Wayland seems pretty promising already).

Likewise from Brazil and likewise would rather see whatsapp gone from my devices. Sadly, I still need it for work and other official matters. Still, I’m slowly but surely abandoning whatsapp, by either convincing people I talk to to migrate to other, less anti-consumer services, migrating myself to sister groups or alternatives in other services, and/or abandoning a group or chat altogether. And all the while being vocal about it by raising my concerns about whatsapp (just saying “I don’t like it and you should move too” can be pretty counter-intuitive with our countrymen). Hopefully, this way, I can drop it altogether once it becomes clearly irrelevant.

But this reminds me I haven’t deleted/left any chats for a few days, so I’ll take the opportunity to do just that.

If you absolutely must get something from Google Play, I suggest Aurora Store, which acts as an alternative frontend for Google Play, so you don’t have to have GApps installed.

If you have use for command line programs, Termux, a terminal emulator, is a great option, and it also works with root.

For reading eBooks, I also have a recommendation, Librera Reader (but I’ll check the OP’s recommendation too).

Material Files and Simple File Manager are great file browsing tools. But if you need a file browser for root specifically, I recommend Material Files specifically.
