I have the double tap home button on my Note 3 set to open my app drawer using Nova Launcher. If I am in an app and then double tap the home button I can go to my app drawer where I can open another app. However, the second time I try to go the app drawer I am always taken back to my home screen. Once I am on my home screen I can again open an app, double tap to open the app drawer...but here is where the cycle repeats. The second time I select the app drawer I can see my app drawer for a split second before I am taken back to home screen though.
Any one else having this issue? I checked with some other people who are on other ROMs/devices using Nova and they dont have this problem.
