I find that everytime inpress the power button in unlock the screen which puts the notifications in the banner and I can’t see them anymore.
I know it’s like a silly struggle, but on other phones I’ve had you can easily check your messages without unlocking the phone entirely.
i struggle with this as well. what i do sometimes is press the power button with the finger i didn’t scan fingerprint and close the frontal camera at the same time 🥲
