Like me and you, I like installing Apps from the Google Play Store. Things I consider before installing an app is its reviews and developer name. Just be on the safe side of viruses. But I have found that the more apps I install and uninstall, there are folders left over from the apps on the storage. It annoys me when my storage is full of empty folders and ones with small pointless files in. Are there ways to fully uninstall apps from the system, no traces of files etc left. Another app maybe? It couldn't be that hard to develop an app which monitors what apps add to the system upon install, and then goes to delete all those changes when the user wants to uninstall? I feel the iPhone doesn't have this issue with remaining folders/files?
