I don't know. Really bad scrolling performance now and constant lockups. Phone not even warm. Will have to jump ship to Android really soon after L920, L930 and L950. Really bad of Microsoft.
That's really bad, sounds like we have very different experiences from .297. Scrolling in edge on my phone is like doing it on any other phone.
Sometimes the phone backup is the culprit. You can try to do a hard reset without restoring from a backup.
1 - Back up using Contacts + Messages app, it makes a backup of your SMS/MMS/Contacts on your phone. This works even if you don't have a memory card, look at the bottom of the screen.
2 - Copy the folder to a computer, together with any files you want to keep..
3 - Perform a hard reset, and don't restore from any online backup.
*** Optional, instead of a hard reset (if you don't think it's enough),
you can use the WDRT to reinstall Windows.
4 - Copy the backup folder back to your phone, use the app in
#1 to restore.
After that you have to download your apps manually, but Store usually keeps track of which apps that are associated with your account.
As a last resort you might consider to use your warranty if you still have one. Mine is 2 years, although it's not the same everywhere.
