Most of the time it is unusable and slow. It randomly crawls, i.e. opening a browser, an input field, or the GMail App will make the device halt for about 10s. It will never get the new Android. Camera was always crappy with LineageOS. WiFi is broken since a few weeks and will constantly just vanish, needing to connect manually.
I almost only ran Cyanogen or Lineage on my devices, if not stock. I tinkered a lot with my Cyanogen installs back in the days, trying to even the bumps and failings.
Any device that has a decent stock image will run better with stock than any LineageOS or CustomROM in my experience.
As I said, I’m currently still on Android 10, but I don’t really mind that.
Any chance you can name and shame those apps for my further edification?
But Google Pay requires it, so does my Health Insurance app (TK, which I don’t use), and the Banking App for DKB (fun fact, they enabled it in a normal update and left many people suddenly without access).
I don't understand what the problem with that should be though.
I used to ROM-hop a lot, but nowadays, I just stay on whatever the official LineageOS build is (for my OnePlus Nord, that’s still Android 10, but I tried stock and couldn’t handle it) and install my weekly updates.
IMO performance is usually better the more random the ROM (so xXx NoLimits > LineageOS > Vendor OS), stability can be very hit or miss with the random ones but is equal for LineageOS and vendor.
Despite Magisk Hide not getting developed anymore, at least on 10 I can pass safety check despite being rooted btw.
