There's lots of bugs despite this being a "stable beta"
Backup and restore setting crashes and so does the colour scheme setting
Not to mention it's not Google certified.
Avoid this firmware and wait for a stable one.
Colour scheme setting crashes and doesn't open when you select it in settings on 12.5.5 stable beta mi 11 ultra.
I would advise nobody download this version .. there's a lot of bugs and no certification
