Fix: Glance Screen Not Working
One of the most dreadful known issues that the Windows 10 Mobile Insider Preview presents is the Glance Screen not working. Numerous Windows 10 Insiders have experienced their Glance Screens failing to work following an upgrade, a problem even Microsoft has acknowledged.

This indicates that the Glance Screen not only ceases to function for users affected by this problem, but they also cannot access or adjust the Glance Screen settings.
In addition, an update for Glance Screen is available in the Store for users affected by this issue, but any attempts to install this update result in error 0x803F8006. Fortunately for users experiencing the Glance Screen not working issue, the following are the two most effective methods that they can use to try and fix this problem while Microsoft works on an official and permanent solution:
