BusyBox

Busybox is an application that is not very effective in itself but to use a lot of other applications that you need to have a rooted phone.

It is important to note that your device needs to use the full benefits of Busybox and other applications that it requires; It will not work if you do not have SU or full root.

This app is designed to run light and fast, allowing you to maximize the limited resources of phones and even wearables.

Pros

1. A Swiss Army Knife for your device This app enhances the ability of other applications to access your device and access the executive vital functions.
2. Designed as light and fast as light and fast, this app combines many essential Unix utilities and allows your android device to perform advanced functions that are not otherwise enabled.
3. Root apps can't work without it! Busybox is the "brain" of virtually all applications that need SU to run on devices.

Cons

Working on rooted devices only requires administrative or superuser facilities to run your Busybox. Without the right opportunities, all the power that the application provides will be wasted (and those applications will need it too!)

In fact, it doesn't matter if you want to keep this app on your Android phone. But you have to keep in mind that it can be destructive for your devices. Besides, it can also expose your Android device to vulnerabilities. So, you have to decide wisely whether you need to download, install and use this app.
