This seems to be a unique issue, which is why I'm posting it. I have quick glance enabled, no problem there, and motion gestures enabled, but when I lock my phone and use quick glance it works once after locking it. If I needed to use quick glance again, 20 minutes later, It won't work. I'm using the correct gesture (It works fine the first time). But afterwards I need to unlock my phone, and lock it again, so quick glance will work once. Has anyone encountered this issue on their phone/know how to solve it? Most of the other gestures work fine, except for answering calls, which I have problems with when using someone else's phone too.
