Android users can manage app storage by using the Google Play Store's app archiving feature, which allows temporary removal of infrequently used apps without complete uninstallation. To enable automatic archiving, users need to go to the Google Play Store app, tap on their profile pic, select "Settings," then "General," and enable the "Automatically Archive apps" toggle. Once activated, seldom-used apps will be automatically archived when storage is low, indicated by a cloud icon, freeing up space while keeping the apps accessible for future use.
