Will stick to Android and hopefully root to add privacy instead.
Privacy is a different concern. The mail app pre-installed on my Samsung phone wanted me to agree to a EULA that lets them process any of my mail. I also find that unacceptable, so I found a different mail client I liked and I did the same thing with the entire phone, basically. It's possible, but it's just no annoying and not something I really want to be dealing with. It seems like we're stuck between a rock and a hard place.
(Yes, I am well aware of the Librem and other such noble efforts, but I can also begrudgingly admit that I'm just not willing to put up with their flaws either.)
I used to love tinkering, but my phone has become nothing more than a tool and I need it to just work. If I forego Magisk and other root-related tools, can I expect mobile banking and such to just work?
EDIT: Seems I can't reply to a reply to this. (Does HN have a depth limit?) I am aware, Cyanogen hasn't been a thing for some time, hence my question: has the situation genuinely improved since then? I would like to avoid buying a phone just to see if it would work for me.
However at some point an update to my bank's app made it refuse to run citing insecure device - it's not rooted so this was a little surprising. I don't know how common that is, no experience with other banks.
If you're so worried about privacy on Android that you'd consider jumping to closed source Apple iOS, consider buying a OnePlus (or other supported) device and then installing LineageOS or another fully open source OS. You don't have to use stock Android and many of the custom OS / ROMs have 0 ties to Google / don't install Google service / etc.
