Here is a good starting point:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3231510/

It describes focus algorithms and helps you go into the field.

However, you should know that usually, the functions needed to control the camera to provide auto-focus are not available for camera phones. They are usually embedded as OS drivers or even in-camera embedded software.
