Metal magnetic ring and sensors

[krazy_loco]

Why would the metal magnetic ring placed on the phone case cause issues with proximity sensors of the phone?

Is a MagSafe case or compatibility okay with the Galaxy s22 ultra?

[Chef31684]

Magnets by nature will cause issues with sensors on electronics as well as they can cause issues with the SPen input on the S22 Ultra

It was a metal ring to use like a magsafe feature

[Chef31684]

I understand that

[notforhire]

when I drove commercially, I had a metal plate on my phone case for use with a magnetic dash mount...no problem. I can't imagine having a magnet permanently attached to my phone. but that's just me.

No this wasn't a magnet ring, but a metal ring.
