Oh they aren’t replaceable easily , I bought all the required tools and pried the phone open in order to replace them.

Just read the news about Truecaller premium having a call recorder in case that’s something you want.

I you are rooted I really recommend BCR, it’s been working great for me :)

I’ve been using CrDroid on my Poco F2 Pro (LMI) for a long time now , have also dabbled with Elixir , Nusantara and a few others which was fun, I love custom roms and tinkering plus MIUI sucks badly.

Also the mire I tinker the deeper I go, I made my first magisk module this year , git pretty good at debugging and root files etc , plus I can restore my phone pretty fast now (I brick it every now and then lol)

This year I also got into battery replacement , I switched out my battery and my camera module, and switched out a samsung s9 plus battery, was pretty fun.

I can answer for Israel at least, public transport is really bad and slow here, it doesn’t reach everywhere, it doesn’t work on Saturdays and generally isn’t on time, sometimes they skip stops altogether and sometimes trips are just suddenly cancelled.
