Rooting the Asus Zenfone 2 results in more apps working with your device. The WiFi Protector is one of those apps you can install after rooting the device. As the name suggests, the app is great at protection your WiFi. While WiFi protection isn’t usually something we think about, this app can stop people from tapping into your WiFi and literally using your WiFi. It’s a powerful app that require access to the root file system to work, which is why you never hear Google or Android talking about it. However, you can be sure that many Google developers probably use this themselves.
