Here's a link the the APK of Gadgetbridge. It's an app to connect a pebble watch or similar.
It worked on my Kyocera DuraXV, but Im trying to install it on a Kyocera Cadence and it won't allow, because it's an app from an "unknown source". Not sure if the app needs to be modified, or there's a setting I can change or set (via ADB?) to allow.
Please help if possible- Thanks!
