Glance is not double tap to wake... 2 different thing... I only see my sister use Glance on her L920. I've never use one myself, so I'm gonna go with it's not important for me... though I think it's more on preference rather than a requirement. Some ppl prefer to have it already on the screen, I don't mind double tapping to look at notifications or clock.
I double checked my package just to be sure
1. No earphone (somehow I don't really mind about this... usually I just throw away or keep it in the box and never use them... I use my own earbuds that's more comfortable.
2. Charger and USB cable is included
3. No wireless charger.
4. Comes with Cyan update.
