I noticed that the Front Panel Display (FPD) app icons (white and circular in shape) (phone, camera, video, music, etc.) were not launching with a normal press. I pressed harder on the screen thinking that it would help, but did not. At first, it felt frustrating that the app would not launch no matter how many times I pressed on it.
It occurred to me that the 2.5 inch screen is responsive to a small area. For example, I am impressed how reliable unlocking the Cosmo with a numeric pin on the front screen with its quite small numbers. So, I asked myself why is it so much harder to launch a Front Panel Display icon than it is to input a pin.
Eventually, I figured out that if I imagined a FPD white circular icon to be an analog clock and lightly pressed at approximately the 7PM location of the circle, the Front Panel Display app will launch. Every time. It works with super light press too.
If launching the FPD apps is frustrating, try tapping a specific part of the icon rather than the whole icon. I don't know if the 7PM location will work all Cosmo units produced; however, launching FPD apps is no longer frustrating and is now easy to do.
Cheers!
