Magisk vs KernelSU vs APatch for Screen Mirroring
Injection-based mirroring needs two things from your root setup: root access itself, and a Zygisk runtime — the piece that lets modules run inside app processes. All three mainstream root solutions can provide both. The difference is how much of it ships in the box.
The short version
| Root solution | Approach | Zygisk story | KoalaMirror |
|---|---|---|---|
| Magisk | Systemless, the long-time default | Zygisk built in — flip it on in settings | Works out of the box |
| KernelSU | Kernel-level root, popular on newer kernels | No built-in Zygisk — needs a standalone runtime | ReZygisk auto-provisioned on deploy |
| APatch | Kernel-patch based, the newer contender | No built-in Zygisk — same story | ReZygisk auto-provisioned on deploy |
Magisk: the path of least resistance
If you're on Magisk, you already have everything: enable Zygisk in the Magisk app, deploy KoalaMirror, reboot, done. This is the most-traveled road and the one most guides online assume.
KernelSU and APatch: equally first-class
Kernel-based root has real advantages on devices and kernels that support it — but neither KernelSU nor APatch bundles a Zygisk runtime. The usual fix is installing one yourself (ReZygisk being the actively maintained option). KoalaMirror does this for you: if no Zygisk runtime is detected at deploy time, it provisions ReZygisk as part of the same one-tap flow. No module hunting, no version matching.
So which one should you use?
- Already rooted? Stay where you are. All three are supported equally, and switching root solutions is rarely worth the churn just for mirroring.
- Rooting fresh? Magisk remains the simplest all-rounder; KernelSU or APatch make sense if your device community recommends them for your kernel.
