Deletes file remnants and scrap APK packages.
Finally, the one-touch App animates pleasingly, displays the amount of freed space after the scan, and generally acts as a system streamlining App, one that's incredibly easy to use. In addition to a smart scan that boosts speed and reclaims memory, DU Cleaner also removes old APK packages. The DU Cleaner App uses a smart algorithm to nail down these digital memory hogs, the file remnants that are causing App hiccups and interface slowdown, but this super-small utility can manage this task easily, and all in under a minute. A single screen tap is all it takes to trigger the memory-cleansing process, then all of that system garbage is ejected from the smartphone's cache. In other words, when DU Cleaner scrubs away leftover files and system junk, raw speed is a natural byproduct. Happily, by taking care of the latter issue, the former problem is washed away. Speed and space are the two features that determine a smartphone or tablet's capabilities. Performance gains aren't the only feature here, though, for DU-Cleaner also frees valuable hard drive and SD card space, the diminishing memory areas that are needed for more photographs and more downloaded Apps. To achieve this function, the handy App intelligently scans precious resources, looks at background processes, and deletes file residue so that those resources are free to boost the operating system. Digital detritus is deleted, scrubbed from the system cache and other memory sensitive areas until phone performance is boosted. DU Cleaner gets rid of smartphone sluggishness by erasing useless files.
