Google seems to be hard on improving the Android ecosystem. The company is silently working on bringing Gift Cards to the Play Store. Today, the big G has brought another new feature to the Play Store – Smart App Updates. The company had announced about Smart App updates during the Jelly Bean keynote at Google I/O this year.
Smart App Updates are like OTA software updates that your phone gets, except that it is for the apps installed on your phone. So, if you have a 30MB app installed on your phone and an update is available for it, you will not have to download the whole 30MB APK again. Instead, only the updated part of the APK will be downloaded and installed, thus saving bandwith.
The feature is already available to all Android users running Ice Cream Sandwich or higher. If not, wait for a few days and the feature should go live in your region soon. Keep in mind that the Play Store download progress bar will show the full size of the APK, but only download the updated part of the APK.
