adb shell su cat /proc/meminfo | grep -E "Swap|Zram"
Alternatively, check ZRAM size with:
: Long-press your new disable_zram.sh file, open its Attributes/Permissions , and ensure it is set to 755 ( rwxr-xr-x ). It must be executable, or Magisk will ignore it. Restart : Reboot your phone to trigger the script. How to Verify That zRAM is Disabled

Or change swappiness (lower = less swap usage): disable zram magisk
If you decide that disabling zRAM isn't for you, reverting the change is straightforward:
ZRAM is a Linux kernel feature that creates a compressed block device inside RAM. Instead of swapping to slow flash storage (like eMMC or UFS), Android uses ZRAM to store compressed memory pages. This effectively increases available memory at the cost of slight CPU overhead for compression/decompression.
When the system quickly needs to fetch an app from zRAM, the CPU must pause to decompress it, leading to noticeable frame drops.
For advanced users who prefer complete control, you can create a custom Magisk boot script to disable zRAM manually. This approach ensures the change is applied reliably at boot. adb shell su cat /proc/meminfo | grep -E

Once upon a time in the land of Android, a power user named noticed their high-end phone felt strangely sluggish. Despite having 12GB of RAM, the device seemed to hesitate during intense gaming sessions. Alex discovered a hidden background process called —a virtual compressed swap space that lives inside the physical RAM.
If none of the above modules work for your specific device or Android version, the XDA Developers forums remain an excellent resource. Experienced community members often share custom scripts and tailored solutions for different device models. This is particularly valuable for flagship devices like the Samsung S22 Ultra or OnePlus 8 Pro, which may have unique kernel configurations or boot processes.

When your physical RAM fills up, Android doesn't just give up and start crashing apps. Instead, it takes the least-used chunks of memory, compresses them (similar to zipping a file), and stores them in a special compressed block in your RAM called zRAM. When that data is needed again, it's decompressed back into a usable state.
Look for SwapTotal . It should read 0 kB . Alternatively, check free -m .
To safely modify your system's memory management, it helps to understand what zRAM does and why it is active by default. What is zRAM?
