I had a phone with that finger swipe routine but that only worked when it felt like it. Or if you had dad a bacon roll or something greasy then my finger might not describe the unlock shape very precisely.
Quickbeam - with my phone you don't have to use the security features to access an incoming call so you don't miss it unless you are slow getting your phone out of your pocket as I am from time to time.
I'm the same as Graphicool1. Except that I carry mine only in my car and fully charged through the "cigar lighter" I wonder if there really is anybody these days who lights their cigars from such a device.
