Magisk on Android 15: 16KB Page Sizes & Compatibility Layer

An in-depth technical analysis of Magisk compatibility on Android 15. Covers the 16KB memory page size revolution, GKI 2.0 init_boot and vendor_boot partition extraction, Private Space multi-user sandboxing, and device-specific hardware compatibility.

Android 15 Technical Specifications for Magisk

API Level: Android 15 (API level 35 / Vanilla Ice Cream)
Minimum Required Magisk Version: Magisk v30.5+ (Magisk v30.7 recommended)
Memory Page Architecture: Introduction of 16KB virtual memory page alignment support with 4KB fallback
Target Partition: init_boot.img (Standard GKI) or vendor_boot.img (OEM modular ramdisk)
Key Subsystems: Private Space multi-user sandboxing, strict 16KB ELF binary alignment

1. The 16KB Memory Page Size Standard

Android 15 introduced native support for 16KB memory pages on ARM64 architectures. While 16KB pages yield up to 10% performance increases in app launch times and lower memory latency, they cause immediate segmentation faults on legacy 4KB-only native binaries:

16KB ELF Binary Alignment Mechanics

# Why Older Root Modules Crash on Android 15 16KB Kernels: Legacy ELF Binaries: Compiled with 4KB segment alignment (0x1000 boundary). 16KB Linux Kernel: Requires PT_LOAD segments aligned to 16KB (0x4000 boundary). Result: Kernel mmap() boundary fault -> SIGSEGV / Process Killed. # Magisk v30.5+ Solution: All Magisk core binaries (magisk, magiskboot, magiskpolicy, resetprop, zygisk.so) are compiled using: -Wl,-z,max-page-size=16384 -Wl,-z,common-page-size=16384

2. Partition Targets: `init_boot.img` vs `vendor_boot.img`

On Android 15, the partition flashing target depends on whether your device uses standard GKI 2.0 or an OEM modular ramdisk:

Standard GKI Devices (Google Pixel 7/8/9, OnePlus 12/11): Target init_boot.img exclusively. Never patch boot.img.
OEM Modular Ramdisk Devices (Select MediaTek & Xiaomi devices): Some OEM Android 15 firmware packages place the first-stage ramdisk in vendor_boot.img. Magisk v30+ automatically detects and patches vendor_boot when required.
Samsung Galaxy (S25/S24/S23): Target the AP tarball containing init_boot.img.lz4 and vbmeta.img.lz4 via Odin.

3. Private Space Sandboxing & Multi-User Root

Android 15 introduced Private Space, an isolated user profile (typically User 10+) with separate encryption keys and app sandboxes.

MagiskSU natively supports multi-user root enforcement on Android 15. Root access granted to an app in the main user profile does not automatically leak into Private Space unless explicitly authenticated by the device owner via Magisk Manager.

4. Passing Play Integrity & Google Wallet on Android 15

To maintain Google Wallet tap-to-pay and banking application access on Android 15 with an unlocked bootloader:

Enable Zygisk in Magisk Settings.
Add Google Play Services and Google Wallet to the DenyList.
Install the latest Play Integrity Fix (PIF) module.
Install Shamiko to conceal root binaries from memory scanning.
Clear data for Google Play Store and reboot.
