Can anyone try this and tell me if they can reproduce this?
Here is my setup:
Ring lockscreen with custom app starter and pattern security
Hold back button to kill application checked
1. Start an app. What I did was start Titanium Backup and began backing up my apps.
2. Lock your phone (display off). Now wake it up, but before you unlock the phone, hold the back button as if you were going to kill the lockscreen.
3. Unlock your phone. The app that you had running before you locked your phone should have been killed. For me, Titanium Backup was killed (it was not backing up my apps anymore).
In my setup, I mentioned that I had the custom app starter. What I've noticed is that if you wake up your device and select a custom app, the app is started even before you unlock the phone. For example, if I choose to unlock into the camera, I would first drag the ring onto the camera bubble. Now the pattern lockscreen is shown, but the camera app has already opened before you unlock the phone. Not sure if this is a bug, but onto my point: if you hold the back button before you unlock the phone using the custom app starter, you will see that it will not unlock into the custom app because if I am correct, it has been killed.
