Galaxy S23+ user here.
After upgrading to 6.1, 9 times out of 10, when I first wake my screen, my screen is completely unresponsiveness for the first swipe or fingerprint scan.
I have to either swipe twice is my extend unlock has unlocked my screen, or remove and replace my finger on the fingerprint scanner for the screen to acknowledge my input.
Very annoying and definitely a bug.
I've tried restarting my phone and have also wiped the cache partition.
Any help much appreciated.
