An app I've had since the OG Droid days was On Call End. Like the name implies, the app lets you control what happens when you complete a call. For example, instead of going to Recent Calls, you can go to the Homescreen. The JB update stopped the app from working. I feel it would be a lost cause to uninstall and reinstall as the last time it was updated was in 2010. Does anyone know about another app like it that works on JB?
