Xposed Installer is a piece of software that allows you to make changes to your smartphone's operating system. It only works with devices running the Android OS. This application comes with a friendly and simple window design and as soon as you launch it you are able to pick what type of changes you want to make. Before making any changes you should create a backup of your device and store it somewhere else.
The app requires you to install the Xposed Framework in order to make modules work. You have to keep in mind that the framework doesn't brings new functionality. The Modules section is made for that. You are able to discover and obtain modules inside the Download section and you can use the search feature to find something interesting. You will find different modules from changing permissions for apps to changing the colors for the keyboard.
To install a module you have to check the checkbox and reboot the device. Sometimes this framework might cause problems, so please make a backup of your important data. Xposed Installer can be disabled without having to reflash your device.
