So I got a rather new (but cheap) Y100 Plus from Dogee with Android 5.1 and ALL Links open to the browser. Even when someone sends me a Location, it opens Google Maps in Browser instead of the App.
I was NEVER prompted with what app to open any link, which is pretty weird, and probably the cause of my problems. That also means that resetting the preferences on my Browser doesnt do anything (tried that). More annoying, "Open Link With" which would have been my workaround doesnt hep, because my browser doesnt give me the share option.
