2. Switch to SU (Super User) mode
3. Type "htop" in the terminal app
4. If you see a value above 4GB, then the SWAP is successfully enabled

Does Not touch ZRAM config

this module unlike others, does not touch the devices ZRAM config, rather runs along side. if you run cat /proc/swaps, you will see 2.

Best Results

For optimal results, open a few apps and keep them running for a few hours. The performance improvement is highly conditional.

The biggest difference i noticed in my case was battery life and less lag.

Device Testing

This module has been tested on Lineage 20 with a device having 4GB RAM. With an additional 8GB SWAP, the device was capable of running more apps and it felt like having more than 4GB RAM. Additionally, improved battery performance was observed. The average memory usage dropped from 89% to 65% with over 30 apps in the recent apps list and using a bulky Gapps package with all the future flags set to true.

Uninstallation

To uninstall the module, simply deactivate the module in Magisk and then reboot your device.
