If you use the -owned ze navigation app, there’s a simple solution to this minor conundrum. ze Up lets you answer the phone without having to touch the display to get back to the navigation screen. You can still use ze for directions, the dialer will still pop up when you receive a phone call, but ze Up will automatically revert back to the ze navigation screen after a few seconds once you accept the call. The app is developed by XDA Forum Member Giladi it’s primarily meant to help reduce those scenarios where you might become distracted while driving. And please, consider utilizing speakerphone, a car mount, or any other Bluetooth connected device that keeps your eyes on the road your hs on the wheel.
