If you’ve been grumbling about how you have to redownload entire apps whenever you’re updating apps on your Android phone, grumbl no more for Google has now activated smart updates on Google Play. Starting today, updating apps will only make you download the necessary components instead of the entire app. In other words, if a 5 MB app only needs 500 kb of updates, you’ll only need to download 500k before the update begins to install and your app becomes the latest version. This makes app updates far more economical and data efficient. Valuable obviously, when on mobile data connection.
