My lumia 920 glance screen and double tap to wake stopped working. I noticed this before I updated to 10586.122 ( from 10586.107) The only thing I did was to put tempered glass on it. I updated to .122 hoping that it will fixed the issue but to no avail. I tried to uninstall and reinstall glance but it did not help. I likewise did hard reset and even that did not produce good result. One thing I noticed with the tempered glass protector is that the bottom and the top portions do not stick well as the 920 has a curve screen. Some dust accumulated already at the edge of both the top and bottom portion. I am just wondering if both the glance screen and double tap to wake are interconnected and so is the problem. Please help to fix this problem
