I was able to install NewPipe via F-Droid on the FLX1s Linux phone.
(Thanks to @Sturmflut for the suggestion.)
I will take a long time to (manually) transfer over all my subscriptions.
UPDATE: most of app seems to work, but I cannot watch videos — I either get a error or they don't play.
F-Droid is currently a bit buggy on my FLX1s Linux phone.
It keeps on asking me to "Allow F-Droid to send you notifications?" over and over again, the bottom menu buttons cannot be tapped (what is under them gets tapped), and the search button cannot be tapped either.
Is anyone else also having these issue?
I assume they will get resolved eventually.
UPDATE: F-Droid started working all of a sudden.
The "Mobile Settings" app was a bit confusing when I first tried to use it.
It just showed me a more-or-less blank screen.
Eventually, when I swiped on the screen, it took me to a menu.
I think it should have shown me the menu immediately. (What was the point of the blank screen from a user-experience (UX) point of view.)
But, either way, I got it working. And, tweaked some things.
I was able to install the Tusky Mastodon Android client, using F-Droid, on the FLX1s Linux phone.
The FLX1s is NOT an Android phone, but can run some Android apps.
In fact, this post was using Tusky on the FLX1s Linux phone.
I tried getting FreeTube working on the FLX1s Linux phone, but couldn't. At least, not so far.
It installs, but — it doesn't open.
