I use my thumb for all phone related tasks. However for casting I only ever seem to get fair, occasionally good & rarely great. What is the best way. And how can you ever get masterful?! I'm just not that fast. And if you do get speed how can you get accuracy??

I tried the thumb thing. It didn't work out well for me. But I have a large screen so that's probably why. hehe
I saw some people say they moved their whole arm?? How would that work?
I might try the face/nose mash method next.
i use my index finger and minimize upper arm movement
rotating the phone helps too
getting ~10% masterful rate
though have found great casts are more successful
