That also depends a lot. Often (e.g. on Fairphone) the stock ROM may lag behind way worse than e/OS.
So if a user has reasons to avoid a Pixel, or just wants to improve their privacy without replacing their device, e/OS may be a marked improvement even on security.
eOS is just Android, so Android apps work.
That aside, eOS has a history of being often behind on security patches and updates, so it is highly recommend to avoid it.
Are there any other Android based OS that are neither Google nor flawed?
GrapheneOS
Thanks. Does it work on a Nokia 7.2 though?
Sadly it only works on Google Pixel. I’d recommend LineageOS, but the images aren’t signed so you can’t lock the bootloader.
