Xposed Installer is more than a program that’s unnecessary for the Android system. It’s a massive project in which many developers have created numerous applications to improve the operating system. This software can be used to remove ads, distribute the buttons’ main purpose, improve battery life, and many other useful and interesting things that will benefit the whole system. Many users refused the Lollipop OS because the Xposed Installer program was not available.
To properly use all these features, you need a special software environment. This is known as the Xposed Framework. It wasn’t easy to transition to the Xposed Framework due to the massive redistribution in the architecture of Android 5.0. Some programs tried to put Xposed applications on a different system, but they often encountered many errors.
