I reset my Lumia 720 (with the Black update), but after the reset the Storage check and Glance options are missing from settings. How do I get them back?
It happens because after a factory reset you need to manualy update the system apps that have been updated since the time your factory OS version was launched. Since you are in the Lumia Black version of the OS, you can't search for updates directly from the Store application, because this option are not available in the Black update. So, to search for updates you will need to use a third part app, like SysAppPusher.The app enables you to quickly check (and be notified of) updates for installed and supported system apps, as well as opening up the ability to add apps from the store you wish to track.
