How to Enable ZRam or Swap in Any Android Rom Default in Boot.img

Hi guys, Welcome back to Techy Buff Today I will guide You How you can enable Zram or Swap in any rom default in boot.img of Android Devices

What Is Zram or Swap??

ZRam is a Linux kernel function that gives a form of virtual memory compression. zram increases overall performance by keeping off paging to disk and the usage of a compressed block device in RAM instead, inside which paging takes area until it is essential to apply the swap area on a hard disk drive. Since using zram is an alternative way to provide swapping on RAM, zram allows Linux to make a better use of RAM when swapping or paging is needed, specifically on older Devices with much less RAM installed. It is pretty helpful for those who have low end Android devices and want to get better performance in their Low end Smartphones. It is a virtual Ram, Not actual Ram but gives some smoothness in your phone
