The main difference between Magisk and SuperSU is how the root works on Android. Based on what the user wants to do.
We will first talk about supersu root how to get the root where it installs itself within the system files It changes the system files and adds new files to the system partition on the phone, but with the enhancement of Google to protect Android it has become difficult to do so that the amendment to the partition of the Android system to send an alert to applications that are trying to detect the presence of root.
Google SafetyNet monitors the operating system from any manipulation, and when it detects any manipulation in the Android operating system, most applications will not work and will not send you OTA updates.
What about Magisk is one of the most important features that does not touch system files, but modifies the boot partition instead so that it can trick safetyNet service and show that everything is normal and allows Magisk Manager to fully control the root settings.
