Default [Q] Screen stays on when shutting down

Hey everyone,

I relocked my bootloader (sadly, no backup of TA partition) and installed 12.1.A.0.266 using PC Companion.

Since installing the update, when I shut down the phone, the screen will stay on for a few seconds. It looks like the phone froze in the middle of the shutdown process, but it will shutdown properly.

This is a minor annoyance, nothing more. Still... does anyone else have this problem?

Cheers
