Unfortunately mobile web browsers are not perfect yet, but at least they are improving.
Hopefully Chrome will fix the flash when changing videos.
We also support using a canvas, but I believe that canvas is disabled by default on mobile as most browsers do not support it.
You can enable using a canvas with,
SDK.useCanvas = true
But, I'm pretty sure it does not work on mobile Chrome.
We also have a free open source Android and iOS SDK for building apps.
