Today, smartphone provides exiting touch experiences. These nice touch applications are based on high speed main processor, graphic accelerator and virtual machine accelerator. However, low-tier feature phone that has the lower speed main processor, no accelerator and has experienced some difficulties for these touch application.

In addition, we invented icon cache and thumbnail file to promote touch performance
