I am going to have my 1520 on this Wed. After read so many problems/issues that you had, my question is: Should I update to the latest dev. version (8.1) before install any app / personal settings to my new phone? Your help is greatly appreciate!
Update all your system apps and then download 8.1
After you download 8.1 then do a hard reset and then again update all your system apps and your good to go and shouldn't have any trouble with it.
Turn off WiFi sense and don't pin Cortana to the start screen. You can always go back to 8.1 if you want?
Well I tried to go back to 8.0 after 8.1, and bricked my phone. So be careful with that.
If there's FEAR, then don't do it, wait for the official release !I will also get my phone this Wednesday what are the chances of me bricking the device?
