I posted #339650 yesterday, asking if there would be interest in modifying a GUI, such as the Monero GUI, to work on PostMarket OS and Ubuntu Touch. Since there is currently no GUI wallet that I'm aware of that works properly, I am now testing out the CLI wallet on Android because while it says Android, apparently it's actually more for the ARM architecture. And it should work on PostMarket OS as well.
This is the first time I've ever tried using a command line wallet, and I can tell that this is going to be a serious adjustment.
