By adding removable elastic 'finger straps' I can now hold my phone securely, never worried about dropping it anymore! After some research, I found a similar product online for $12-18. My version IMO is just as good, and you can make several for a fraction of the cost.
My solution works for ALL cell phones, and tablets too with some modifications. For iPads or other tablets, add an extra 1-2 loops.

Step 1: Materials and specs
1) 1" wide x 7" long ELASTIC band. This I found to be okay for average size hands and a snug fit. You can adjust the length for larger hands or if you want a looser fit.
2) HEAVY-duty velcro. Get the strong kind. You will need a 3"x2" piece for a large phone.
3) Sewing machine with dark thread will make quicker work. Hand sewing is optional.
