There are a number of ways to remove and/or eliminate junk files from your computer and CCleaner is one of the easiest and most popular cleanup utilities but, how about your Android-powered phone? As you may know, certain apps tend to forget to clean up after themselves when they’re uninstalled which is why, after testing and uninstalling apps from your device, your might find the SD card cluttered with all kind of unnecessary files. As CCleaner for PC, we have SD Maid which is a free cleaner tool for rooted Android devices. This app allows you to scan and clean all those residues on your SD card as well as temporary files, cache files, logs and so on from the Android system.
