Hi,
What launcher do you use?
Can you please use another phone to take picture of your Axon 7 phone on Main home screen?

This is only happening on the Axon 7. My Nexus 5 and Samsung tablet shows the menu option at the top right corner but the Axon 7 doesn't have that.

I've also tried long pressing the app drawer key which only ends up opening the app drawer.

Heads up for those planning to buy this and use MM regularly.
