The fingerprint reader under the screen is unreliable (to say the least).

I had a Note 9 and the fingerprint reader on the rear just worked. The rear sensor was really useful at night and much faster to unlock when picking up the phone.

The under-screen reader doesn't work 90%+ of the time to unlock and seems to be weirdly even less reliable in apps, so I still need to use my PIN, which makes my S22 Ultra a productivity blocker rather than an enabler.

For business users will also post an issue with the camera when scanning documents.... 

Should've kept my Note9 - still going strong for the person I gave it to.
