Does the ultrawide have OIS?Developer access is gained through tapping the miui version window in detailed info and specs section, about 6 times. Careful though, as screen dpi can send things a bit 'screwy' if you got wild with the numbers.
Gotta say, I googled the camera rattle when I got my 13 ultra, having 4x 50MP cameras all with OIS, the thing sounds like a babies rattle!
