How to "Quick Load" an App
Here's the thing. This doesn't usually work, so don't get your hopes up. Still refreshes and speeds up the app.
I am using Xbox smartglass as an example
Special Wiggle Mode
Have the app you want on the third screen. Put your apps I to to special wiggle mode.( See "How to restart your device without using the power button" .
Press the Home Button
Now hit the home button. Pretty simple.
Darken App
Now swipe back to the third screen. The app you touched to go into special wiggle mode should have a dark tint to it *see picture*
Open App
When you open the app, it should be "quick loaded" or refreshed!
