My S7 was updated last sunday from v0.19 to v1.0.
Last night, the phone was frozen: the screen was locked and display the hour (which evolve) but no way to unlock it which is quite worrying.
The only thing that works was to reboot the phone by pushing the 3 buttons (2 volume keys and the Power key) during ~10 seconds.
Thanks for all to the great team.
tank you for the information, i had the same bug… But i spend 2 days without smarthpone!
I changed with an old android but i lost everything!
