Installation Instructions
If you already have Magisk installed, you can directly upgrade through Magisk Manager
For installing Magisk the first time
Make sure to remove any other root, best to restore your boot image back to stock
Via custom recovery:
Download the latest Magisk zip file
Reboot to a custom recovery and flash the flashable zip
Via Magisk Manager (Only support v14.0+):
This method does not need root, and also does not require a custom recovery.
However, you MUST have a stock boot image dump beforehand, and also be able to flash the patched boot image, either through fastboot/download mode or ODIN
Install the latest Magisk Manager
If you're planning to flash the patched boot image through ODIN, go to Settings > Update Settings > Patched Boot Output Format, and select .img.tar. For normal users leave it as the default .img
Press Install > Install > Patch Boot Image File, and select your stock boot image file
Magisk Manager will now patch your boot image, and store it in [Internal Storage]/MagiskManager/patched_boot.img[.tar]
Flash the patched boot image to your device and reboot. Voilà!
Check whether Magisk Manager is installed and the version matches the latest one in the OP
If for some reason Magisk Manager isn't installed/upgraded automatically, please install it manually

Magisk manager is a magic mask to alter system systemless-ly. Might that term be difficult to understand right?

There might be a question raised in your mind that what magisk is? Magisk is the best alternative of Chainfire’s SuperSU. Topjohnwu develops Magisk Manager. He is the best developer who developed magisk. If you have installed the SuperSU on your device, then you might have seen the issue that you can’t run the banking applications on your Android.

You might be confused about what is rooting? We can say that rooting gives you privileges to modify the software code on the device or install other software that the manufacturer wouldn’t usually allow you to. You can read more about rooting android phone

Many developers are coming with magisk pre-installed on their ROM. They are implementing the magisk just because of the amazing features of the magisk manager apk and the way you can use any application without any issues. The default choice of most of the developer is now magisk.

Let’s take an example

Suppose you want to run banking applications and whenever you open the application you will get a notification saying that your phone is rooted and you won’t be able to use this application on your device.

Now, to run that application you will unroot your phone and do your work in that app and again root your phone with the help of Chainfire SuperSU. Rooting and unrooting your device is a lot of lengthy processes, and no one likes to do such as a big task again and again.

What if you want to use that banking application urgently? You won’t be unrooting your phone again and again. This the reason why developer Topjohnwu came up with an application which hides the root from your device.
