As an Android user, most of us want to heavily customize our Android devices. Rooting an Android device opens the unlimited possibilities of customizations that include installing rooted apps, hibernate background running tasks, improve battery life, lock screen or status bar changes, etc. It also offers uninstalling system apps, edit/delete system root files, installing custom modules, and more. All of these things can’t be possible without rooting.
What is Magisk?
There are two most popular and widely used rooting methods available such as SuperSU and Magisk. Both the SuperSU and Magisk offer root access but nowadays, most of the developers and users prefer Magisk. Magisk is a system-less root that enables root access over the system components without affecting the system core-files.
Therefore, Magisk alters and stores the temporary files in the device boot partition. This is a quite safe method and effective as well. It doesn’t hamper Google’s SafetyNet security feature and other banking apps also work fine with Magisk. Magisk comes with a Magisk Manager app that offers rooted device status, downloading & installing custom modules on your device, and more.
- Your device warranty may void after rooting.
- Rooting will block the software OTA updates.
