I've just bought a Fenix 2 and it doesn't sync with my Samsung S4 mini although I’ve verify it works with a S5.
Will Garmin fix this connectivity problem?
I will be glad to assist you. This issue was brought up recently in the forum at the link below.

"Although the hardware for Bluetooth Smart is present in the Samsung Galaxy S4 mini not all devices have the required software to support it. This particular device model required Android version 4.3 or higher to utilize Bluetooth Smart. If you do not have the minimum Android 4.3 check with your device manufacturer or carrier and see if an update may be available". Unfortunately this is not an issue that can be corrected with an update to the app or the fenix2.
