https://www.youtube.com/watch?v=xLfFWXUNJ_I It’s more of one playlist than a channel about quantum mechanics on Russian, but as I see it has English subtitles. A fairly clear explanation with a small amount of simple mathematics, probably the minimum that is possible. It helps to understand at least a little such a complex and illogical science for the average layman.

It has sufficient list of programs: browsers (I use firefox), ebook readers, fractal (matrix), telegram, maps, that works good enough on mobile at least for my daily use.

I use postmarketos with phosh. It’s kind of viable, but it has some infrequent bugs. For example sometimes, quite rarely, the call menu may freeze after the call and not respond to touches until the reboot. The camera doesn’t work at all. But there are positive aspects, an ordinary Linux terminal and the usual convenient console programs. :)

You can turn off your phone at least sometimes. :) But this of course does not solve the problem.
