As for smartphone, I have a few Pixel 3 XLs I'd like to test graphene and lineage on. In general I'm kind of over smartphones because browsing the web on them (the main thing I do with them) is suboptimal compared to a computer/laptop that can run uBlock and NoScript, so I will probably mostly just leave an iPhone-sized hole in my life.
The Nokia 106 is also good for receiving SMS, which is the only thing I really have a non-data SIM for at this point.
I carry a battery powered gl.inet wireguard/lte wifi openwrt router with me with a Google Fi data SIM in it for internet. I have root on it and can write my own iptables rules, and it only sends traffic via the vpn.
They're pretty painless to use, too; there's an 'Add-ons' option in the main ⋮ menu with an entry for each extension. Tapping an extension's entry opens the usual extension dialogue in a full-screen view, and tapping 'back' in that view has the same effect as closing the extension dialogue on a desktop browser.
So you can use NoScript to enable a script and reload the page in...5 taps. It could be worse.
Also, I don't use Firefox due to its telemetry.
More in the stream of neverending censorship bullshit from the App Store.
Apps aren't even included in "backups", so restoring a device from backup won't actually put it into the state it was before: you get the current versions of any apps (if they are even still available, sometimes they aren't) re-downloaded at time of restore. This is, of course, contrary to the entire concept of what a backup is for.
Of course, you can't download any apps at all without an Apple ID, and also providing your unchangeable hardware serial number to Apple (transmitted when you launch the App Store like a supercookie). You also can't get the Apple ID without providing a telephone number that can receive SMS, so you basically have to dox yourself to restore a working backup.
I've had every single iPhone that has ever been produced (except the 3G - I went from 1 to 3GS), but I'm fairly confident I have purchased my last one.
