I have an old Realme GT NEO 3 with the stock ROM. There was no LineageOS ROM for it when I got it but there’s been one for two years now, so I may give it a try eventually.

The camera is not good but apart from that, it works. I have Google apps installed on this one and use mainly Gmail and Maps. Maps is shitty but I also use openstreetmaps on the web through Firefox. I don’t have the YouTube app and watch videos in Firefox, with uBlock Origin, Sponsor Block and Video Background Play Fix. I tend to use the websites, or FOSS apps if possible through F-Droid. No weather app, I just go on the website with ads blocked. But I don’t mind paying for some apps that I use if they are useful and don’t have ads. Ads are the devil.

And my backups are simple, using FolderSync connecting via SSH on my headless Orange Pi.
