What is Zygisk?
Zygisk is Magisk in Zygote. This will run parts of Magisk in the zygote process to make Magisk modules even more powerful. This is also a very important part of the philosophy of Magisk “getting out of the way”.
When a process is on the aforementioned denylist, Magisk will cleanup the memory space of the process to ensure no modding is applied (P.S.1). Zygisk is still WIP, and more details will come once the implementation is ready for beta testing.

How does Zygisk Process Android shared code?
Zygote is a special Android OS process that enables shared code across Dalvik/Art VM in contrast with Java VM where each instance has its own copy of core library class files and heap objects.
Efficient and fast app launch is achieved due to the fact that Zygote starts by preloading all classes and resources which an app may potentially need at runtime into the system’s memory.
It then listens for connections on its socket for requests to start new apps. When it gets a request to start an app, it forks itself and launches the new app. It serves as a parent to all Android apps.
This forking feature comes from Linux kernel implementation of copy-on-write resource management technique.
Forking involves creating a new process that is an exact copy of the parent process. It doesn’t actually copy anything, instead it maps pages of the new process over to those of the parent process and makes copies only when the new process writes to a page.
All processes started from Zygote use it’s own copy and only one copy of the system classes and the resources that are already loaded in system memory.
Zygote is designed not only to respond to fork requests by new apps, but there is one process that the Zygote actually starts explicitly and that is the System Server process.
What is the use of Zygisk?
The use of Zygisk is to better Hide Root from Banking Apps and to make Magisk Modules & Xposed (LSposed) Modules more powerful. Zygisk uses Zygote in Magisk Manager to better use the shared Code of Android OS.
Zygisk helps better preload classes and resources of Apps to launch Apps faster. It even hides the root before Apps start to process after booting the phone.
That’s what I mentioned, it can Hide Root even better than MagiskHide.
How to install Zygisk
To install Zygisk in Android to root your device, it’s very simple.
Zygisk can be found under Magisk Manager and Zygisk is a part of the Magisk. So you cannot install it separately.
To enable Zygisk inside Magisk Manager, go to Magisk Manager Settings and then scroll down a little until you see an option as DenyList under Magisk Section.
If you want the detailed process then follow this link to Enable Zygisk in Magisk Manager. You can find the process at the bottom of the post.
To install Magisk you can follow this full process guide to install Magisk in Android 12 and below

Zygisk SafetyNet: SafetyNet Fix Android 12 – SafetyNet Fix Magsik
If you are looking for Zygisk SafetyNet, then there is no such this as Zygisk SafetyNet. As I mentioned earlier Zygsik is a part of Magisk and SafetyNet is a Magisk Module to fix SafetyNet in Android.
If you want to bypass SafetyNet error or want to fix SafetyNet Error in Android 12 and below then you can follow my other guide to bypass SafetyNet in Android with simple steps.

Zygisk LSPosed: Zygisk Riru – How to install Riru LSPosed
Zygisk LSposed is a new Xposed framework for the Magisk. Xposed Framework was long retired but then EdXposed came to replace the Xposed Framework.
Now, EdXposed is replaced by Riru LSposed which uses Zygisk’s Zygote process to work in Android. So if you see clearly, nothing has changed except for the name.
If you want to install Zygisk Riru or Riru LSposed in Android 12 and below follow the link. It has a complete guide to installing Riru on your Android.
With the help of LSposed you can install Xposed modules in Android. But not much is available as Zygisk LSposed is new. So you can definitely try out Riru LSposed.
