I have just started experiencing the 'apps do not open' problem. Indeed, in order to write this post I had to start my laptop as I cannot use the browser and the CrackBerry app in my Z10 devise. The only app that I have managed to open is the Message Filter.
I have tried rebooting (5 times) but the devise is still frozen.
Right now the devise is frozen on the active apps screen. I am now rebooting and hoping for the best.
