Swap is a process information of running application exchange from and to, to and from RAM and swap file. When we run an app, the running process will be written on RAM and then it will written to swap file. So when the swap file is already have the process information that needed, RAM doesn't need to create it again, thus this will bring more empty RAM space, more application can be running at the same time, and more responsiveness.
Requirements:
* Rooted.
* A file manager with root explorer ability.
* Update latest Busybox
* UNIVERSAL INIT.D.apk app.
* INIT.D DISABLE ZRAM SCRIPT.
download: via MEDIAFIRE (original) | via USERSCLOUD (mirror).
* RAM MANAGER PRO.apk app.
* (Optional) DISK INFO PRO.apk app.
* (Optional) MEMORY LOCKER.apk app.
* Brain :v
Steps to increase RAM performance on Android device with swap file to /cache directory
Creating swap file on /cache directory
Open the RAM Manager Pro app and don't forget to give it superuser rights. Open the sidebar (klik the top left icon), then tick the "Set on boot", after that tap "Extra" -> Tap "Clean cache" / "Drop cache" first, then tap "Archive exchange" / "Swap file". And then create swap on /cache. Create your desired swap file size, use app like Disk Info to know your total /cache size. Of course the size is can not exceed the total of your /cache size, just left it 30 MB or more for caching process.
For Samsung Galaxy V SM-G313HZ device, you can make about or less than 170 MB.
Why on /cache directory?
Cause' based on my research :v this directory have the fastest write / read speed than other directory. Making the swap file on other directory is likely will make swap is slow to accessible thus less usable. Note that i am using Samsung Galaxty V, a mid-entry device, maybe and maybe it will different on other Android smartphone with better hardware (maybe :v ).
Deleting / disable the ZRAM
Zram is work by compressing the RAM to create more empty space. The hardware will be more burnened because it have to "compress" RAM. So by disable the Zram will conserve more resources to do more important task on our Android smartphone (lag reduce).
Make sure your Init.d app is activated (the switch is on). Copy the INIT.D DISABLE ZRAM SCRIPT to system/etc/init.d/ directory, set it permission (chmod) to rwxrwxrwx (777). Done! Reboot your Android device...
After reboot, wait a while (2 minutes or more). And look the Swap file size on app like Disk Info pro. If the swap size is equal to what we just created, then the swap is success.
Optinal Step
Install and open the Memory Locker app, and then lock the RAM Manager app. This is just to reduce the chance of RAM Manager being killed by OOM process.
OOM (Out Of Memory) is a process that often happen when Android is running out of memory (RAM). Android must kill background app process to make sure your currently opened (foreground) app / game is not force close caused by no memory (RAM) left.
Because this is Swap, so the benefits would not instantly feel by us, we will feel the difference after a while we using the device (the Android device is more responsive).
Remember if you using some cleaner application, DO NOT clean the cache partition / directory. Otherwise you must recreate the swap file again.

Just a simple man with simple hobbies like playing games, listening music, and read about new things. Enjoying blogging as hobby since 2014 and later caught interest playing with his first Android smartphone since 2015, he then combined the two hobbies on this blog and it is a great time killer for him.
