I keep it on my person, so that no one can get their mitts on it.
I have a neck strap tied to the case, and if not using the phone, it is in my shirt pocket with the strap around my neck.
No water splashes, no pick pockets taking it away from me.
I use a swipe to open on the phone, I used to use the Trace a Pattern, but that is a PITA for me, so I ditched that.
I am not one to lay a phone down on a counter, or a desk and get up and leave it laying there.
If at a store front, the neckstrap is around my neck.... I don't get involved with a sales person, register clerk, and loose track of the phone.
I have never lost a phone, ever.... always a first time, but I have always tied them to me. Always.
