While smartphone manufacturers have started offering 32 GB storage as a base in entry-level smartphones, with at least 64 GB in flagship phones, there is still need for more storage. One of the ways to give users more storage space is to clear space for application updates, new applications, and OTA updates.
It looks like Google is working on a smart storage feature that would automatically flag some apps as “inactive” and deprioritizes the generation of cache files for the particular app. The app would be marked as “inactive” if it hasn’t been recently used in the foreground and the app package isn’t being used by another app package in the background.
