Last month Google released Developer Preview of Android Oreo 8.1. As noted by some developers a recent update to the Android 8.1 Oreo AOSP framework includes a feature that will free up some disk space on your Android device when you’re running low.
In case you storage space starts running low, Android will automatically determine some inactive apps and clear its cache. Cache includes temporary data that has been generated by the device in order to function smoothly and efficiently. According to XDA, applications that have been inactive for a specified period of time are considered for this “downgrading”. This feature will neither uninstall the app nor clear any data. Its just that once the cache has been cleared, the app will have to re-cache next time when you open.
How much free space will you get?
It all depends on the cache size generated by the application. For example, Facebook generates nearly 400-500 MB of cache, so if we stop using Facebook for few days, then Android will automatically clear it. Still it hasn’t been found how long will the app need to be inactive.
It’s great to see Google adding long demanding features in Android Oreo 8.1 like battery draining app indicator, and now space saving feature. Lets wait and see how many of these make their way into stable release.
