Android doesn’t allow rolling apps back because there’s a chance it could cause other (possibly more serious) issues with app behavior. Newer versions of apps might support features not available in older versions, altering the app cache (potentially including how it’s stored or read). This means there’s a chance an older version will be unable to read the newer version’s cached data, causing the app to crash or misbehave.Īnd there’s the rub. You can’t easily roll an app back without also clearing cache, which erases all user settings or custom layouts. That’s why the simplest option available for rolling an Android app back is to uninstall that app and reinstall the last known working version. When you uninstall the app, it clears all data and cache related to that app (note: this doesn’t include downloaded files or those written to other open directories), so you start fresh with a clean install. The exception is system apps - anything included in the Android OS, like the dialer, for example. If you get a problematic app update (usually through the Play Store, so this primarily applies to GMS devices), you can roll this app back. Why Android app cache and data are important (and what they do) However, this will still clear cache and data, same as uninstalling an app - you just won’t have to reinstall it to use it. App cache: This is where temporary files related to the app’s functionality are stored.Since we’ve already made it clear that app cache and data are crucial to an app’s behavior, it’s important to talk about what each one does. App data: This contains important app data.Frequently cached data will decrease load times, speed up searching, and more.
