I’ve always been a Stock Android fanboi, but I really wanted to buy a foldable, so got myself a Galaxy Fold 4 last year. This is the first Samsung I’ve owned after decades - my last one being a Galaxy S2. I removed all bloat (including crap like Bixby) using Universal Android Debloater, and using a custom launcher, OneUI stays out of the way for the most part. I don’t really miss stock Android. With my current setup, there’s no performance issues, no TouchWiz bugs/annoyances like in the old days, everything’s running pretty smoothly.
In saying that, ideally I’d love to unlock the bootloader and run LineageOS on it, but there’s no build out for it yet (and unlikely there will be one for a long time), also, I’m not sure if I want to play the whole SafteyNet cat-and-mouse game again. Shizuku works great for apps that need higher privileges, I use Droidify and open-source apps where possible, life is good.
