Applications feel like they are always getting bigger in size, straining your phone’s resources and your data plan. Google has tried to counter this with app bundles, a system that lets developers build multiple versions of their app for different device configurations – the Play Store then downloads the appropriate APK for the user’s phone. Now Google wants to take things a step further with “app install optimization”, which will study which part of an app is initially used, and to improve the update and app-launch process for that Use data.

App install optimization is not currently available on the Play Store, but 9to5Google has seen a support document for the feature that is already live. When you open an app for the first time, Google will monitor which parts of the app you use and which parts you do not own. When you first download Instagram, for example, you can spend the first ten minutes setting up your profile and finding friends. If this is the case for a significant number of users, the Play Store will download that part of the app first, unless you uninstall the posting tool or story viewer, trying to strengthen them or your connection.

This data can also be used to improve resource management on your device. Instead of opening the entire app in RAM, your phone can load the parts you use, reducing the load on the processor and the amount of RAM required.
This is in line with Google’s existing privacy policy, so none of your personal information will be used, and it will not appear to be anything outside of the app in question. It will not collect information about what is downloaded or uploaded in the app, so posts you have seen or created on social media will not be sent back for analysis.
When application install optimization becomes available, Google will let you exit the process. To do this, open the Play Store settings page and close the feature. This will only disable the analysis of your usage, so you will still benefit from that faster load time resulting in the data being processed by everyone else. 9to5 states that Play Store version 25.5.13 includes references to the feature, so we can expect it to become available soon.
