This app is open source;
What is the problem: The problem is shown in the BACON-347 (https://jira.cyanogenmod.org/browse/BACON-347). There is some ghost touch above status bar which cause to open notification panel. After first touch to screen, phone assume that these two touches releated (Your touch and ghost touch) and tell to system there is a slide from first touch to second one. This action opens the notification panel. But if the second touch is for hang up to call phone cant do that because it assume that you want to open notification.
How this app works: During a phone call, this app put a view above status bar and absorbs the effect of ghost touch(When this happened, fix count increase) After user's first touch, if user try to hang up call, app assists user and close the call. But if user touch any other position other than close button, app closes and dont open the notification panel. That is all.
