I don't really understand how people manage to type with two thumbs while holding their phone securely. I use my left thumb and my right index finger, with my right thumb supporting the base of the phone.
I use my left pinky to hold the base of the phone. Lots of people with bigger phones use one of those stick on things on the back and hold it with their index and middle finger.
