Loaded DP 8.1 on my Nokia Icon last week. I like the expanded feature set, but it has become increasingly buggy (wifi/bluetooth issues, etc.). I want to do a hard reset to see if that helps (as has been recommended in this forum), but would appreciate it if someone could walk me through the procedure, since I would prefer not to wipe all the data and/or inadvertently reset it to original factory specs if possible. I am particularly worried about losing music files/playlists on the device. Thanks!
