Fast Root Instantly

Fast Root Instantly is an app that lets you activate different optimization modes that help you improve your device's performance, battery life, or the general stability of the device. In order to use Fast Root Instantly, as its name suggests, your device needs to be 'rooted.' This is the only way you can possibly use the different modes offered by the app.

From the left drop-down menu, you can select the different modes that Fast Root Instantly offers. That said, be very careful when using the app if you don't know exactly what you're doing, since each one of the three optimization modes will cause a series of changes to your device.

Fast Root Instantly is a pretty powerful optimization app that offers some very interesting options. Plus, unlike other similar apps, it doesn't show annoying constant messages.
