Iirc, there are unofficial ports of LineageOS for newer devices. Also, I’ve been using another system, ArrowOS, in its vanilla form, on a Redmi Note 10 Pro phone I have, and it’s working fine so far, so maybe an alternative for your case if you don’t find a decent phone compatible with LineageOS?

Duolinguo feels more like a very annoying ad than a learning tool, often under-explaining what it tries to teach while heavily penalizing and shaming the user for getting things wrong.

What I would suggest, other than hiring an actual teacher, would be to immerse yourself in works from their language, such as music, comics, books, movies, and so on. Also, Spain’s Real Academia Española has a dictionary+conjugator site that is VERY helpful, even for “dialects” such as the Latin America variations (link for the tool is dle.rae.es). Finding someone to try to talk to in Spanish may also help, although getting to know some of the grammar beforehand is advised.

Now, as for either free or FOSS programs specifically for learning the language, sadly, I’m not aware of any.

On the plus side, this gives people plenty of time to tackle their ever increasing backlogs, and also to give companies more reasons to put out a functional product in order to compete with all the kilometric backlogs people already have.

Same as the past 10 or so years, from what I can tell.

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.
