18.104.22.1681/22.214.171.124 seems a little buggy with Telenav 5.1. When launching the app locks up. Also, scrolling through different apps, eg-Mail, Calendar, Address Book is not as smooth as before, kind of a "jerky/framing" feel to it. I'm wiping and reloading the OS and will also reinstall Telenav to confirm. Otherwise it's back to Sprint/Bell Mobility OS v126.96.36.199/188.8.131.52 for me.
BTW, the ringer/alert volume wasn't fixed for me.
