I encountered some storage troubles with my 1020 and did a factory reset, restoring my settings afterward. However, while the phone says that I still have Lumia Black installed and I still get notifications on the Glance Screen, I can't find the options to change the Night Mode colour anymore. I also can't seem to set the Glance Screen to "peek" anymore, even though that was something from Amber if I recall. Someone help, if you can!
