How is this improvement in speed achieved? Is it some sort of black magic or witchcraft? Nah, the bump in speed is credited to the use of algorithms that make the browser more efficient in dealing with data retrieval and storage. And the update also brings some new features like the Web Applications Center which allows users to add web apps to the browser. And the new Image Viewer lets you create a photo album effect using all of the pictures on the webpage you're currently viewing.
The UC Browser now has a widget for quick access to the "rich services" on the browser, right from your home page. The update also includes the usual performance improvements and adds support for more regional languages. It's all just a free download away from the Google Play Store.
