Ugh. This makes me so sad. I was very close to buying a Fairphone 2 or something for its repairability, but I ended up getting a recent Samsung model anyway because it beats the crap out of everything else in almost all categories – especially ones I value highly, like nonexistent shutter lag, weather sealing, battery life and such.

But they're also very anti-tinker, from what I understand. The more I read about stuff like this, the more I'm thinking about rooting my phone just because I want to be in control. I hate handing over my security and system maintenance to a large corporation who barely has my interests in mind. However, rooting a recent Samsung phone is a one-way operation and they can detect it and refuse service under warranty in some jurisdictions. I don't know what to do!

Wait until warranty is expired or you have saved enough to replace it.

Next time: consider buying second hand if that is an option where you live. Should give you more options wrt 3rd party sw alternatives.
