For me, the double tap does work but the Glance does not. It has been so since build .29. Even hard reset does not fix that. I have tried all possible steps that people can suggest to no avail. Now I have given up thinking that only a FW update from MS can bring it back.
Ironically, after I updated to .29, the Glance worked. Only after updating when I did the hard reset, Glance turned off and never came back. Even the Glance setting closes as soon as launched.
Updating from Windows 8.1 Phone directly to the current build will most probably keep your glance intact. Do not hard reset or it may start giving problems again.
