I had locked my phone as usual yesterday afternoon and everything seemed normal. I let a call roll to voice mail and heard a few text message notifications come in and when I finally went to check everything before bed, when I hit the power button to wake up the screen instead of seeing the 9 dots to draw my unlock pattern, I had the puzzle piece waiting for me telling me to drag it to unlock the screen. Thereafter, I simply had to swipe across the screen to unlock it.
As far as I know, I have not received any updates, my uptime shows 200:43 and some change so there hasn't been a restart and I am just wondering if anyone knows of any reason why I should have suddenly lost my pattern unlock.
