The store apps Google Play has changed the procedure for updating. Previously, during the update installed software system is fully downloaded the APK-file and reinstall the application virtually from scratch. Now, load only the changed or new files, not the entire archive APK.
As reported Android Police, during an update on the phone still shows the entire volume of applications, so that changes can be noticed only by using accounting software web traffic. As an example, the site has an updated Instagram – instead of 13 MB to install only 3 MB upgrade.
Most likely in the near future, Google officially announced the innovation.
