I notice that whenever I press extra+info it bounces back. This has started after my installing the latest updates made available for those in Dev Prev. I don't know whether anyone has noticed similar problem.
I'm still on Lumia Black. I know this by changing my region to the UK. After changing to UK Extra+Info stopped crashing. When later I reverted to US it resumed crashing. I can now confidently report that the reason for the crashing of xtra+ info and a number of apps in my Lumia 1020 is changing region to the US.
With me too, Don't know what to do? searched whole internet for solution, just came upon that to solve this problem downgrade it to previous firmware and then re-install cyan update. Contacted Microsoft and many other this solution sites. but not getting any proper solution.
