Hello guys. Yesterday I've upgraded my L620 to WP8.1. After the update is complete and get used to it, I decided to move some of my apps on SD, and in the same time, some changes to regional settings lead me to a restart. When my phone restarted, I had no apps in app list. The apps are still there coz i can open them through Cortana. This morning, I check for updates in the new store, and seems that the apps updated reappeared on my app list, but nothing else. No Calculator, phone, messaging, no settings ....what can i do? Thanks in advice.
