I use it on SE 2 as accesbility feature. Really useful for accepting calls or stoppong alarmms and denying notifications.

I know it is not the same with s9 but does the job.

I dont. I take it off during night/sleeping. And also during shower or bath. Also tkae it off ocasioanly to clear sweat and prevent itching.

Uh, Apple live wallpapers already in real life tough?

It annoys me when i cant identify the source of rattle. When i find it, doesnt bother me much. Fixing panels are beyond my capability anyway.
