I tried that approach and still got nothing. I contacted Sprint and they confirmed that the app is not available on my phone.
That's really strange. This was the first thing I downloaded when I got the One right after launch. I use it often. Maybe use your browser to go to http://www.telenav.com/products/scout/. Maybe that will work.
The app is pre-installed on my HTC One, but does not work. When I select the app, it brings me to the Google Playstore which states, "the app is not supported by this device". It doesn't even appear in the playstore when I perform a search. I really liked the telnav app on my previous phone and would like something similiar. The google nav currently on my phone sucks. Why would Sprint promote an app that's not supported by it's flagship phone? WTF!!!!!
