What is Magisk?
Magisk is a systemless rooting solution for Android devices. Magisk modules (like these apps) are designed to be installed via the Magisk Manager and modify the system without altering the system partition.

Warning: Magisk apps are only for advanced users who have an unlocked bootloader and Magisk installed. Do not use these if you do not know what Magisk is or if your device is not rooted with Magisk. Using Magisk apps incorrectly can cause your device to malfunction or become unbootable.
