Couldn't lock the screen last night.

Hi, yesterday i was trying to lock my device with the lock button on the right, but it didn't work. So i had to go to Settings\About and restart it from there. After that i could lock my screen again. I guess it's a software bug. I have the latest software. Can anyone confirm that?

No. This was the first time.

Sounds like a rogue app
