Enjoying the new update on my s21 but the one bit I find annoying is removing the option of automatically unlocking the phone when I put my pin and not having to click OK again. 🙃
Seems the update requires 6 digits to view the option
I managed to bypass requirement of 6 digit PIN to have ability to unlock without pressing OK. To do that you need to put your desired 4 digit PIN and add 2 more digits to get checkbox visible, then you need to untick and tick option of confirm PIN without pressing OK, next you remove last 2 digits and confirm settings. This procedure allowed me to get my S23 on OneUI 6 unlocked using 4 digit PIN without pressing OK.
Changed set buttons,WiFi Bluetooth,etc back to blue highlight,it certainly did not look right in B&W. Also changed the way phone works,samsung added useless stuff,I rooted phone and took away bloatwear. I never use Samsung apps.
