I use an otter box case and they are tough enough but mine is pretty new and the phone gets knocked out while working or shed hunting.That brings up the app question,good thing I have Life 360.I have used it 3 times this week to find it in the timber.I like this also as a way for my wife to be able to find me if there was a incident.We used when our daughters were growing up and it's nice to know they are ok traveling back and forth to college.Anybody find better cases
