Do not turn the screen off when there is an incoming call

1. Connect to a charger and have the screen off
2. Call the phone, screen turns on to show UI for answering
3. Pick up the phone and disconnect it to answer, screen turns off

If there is an incoming call, the screen should never be turned off automatically. The app should temporarily suspend or something to allow for normal phone operations. This affects Skype as well. Maybe make exceptions for calls and notifications? Anything triggering the user to interact with the phone while it is charging.
