How to increase RAM in any rooted android device

In this section we're going to explain how to increase your RAM with a rooted device. The trick involves creating a partition on your SD card, which will act as a secondary source of RAM. To do this, we will be using the ROEHSOFT RAM Expander (SWAP) app. You can download it from here.

Here is the Play Store description of it:

• Free SD card memory as a RAM use (SWAP RAM / SWAP MEMORY)
• Swapfile RAM expansion up to 4.0 GB (file system limit)
• No limit on SWAP partition! 
• The usual performance degradation when paged not occur with SD card from class-8 
• Widget for PNP swap (swap on / off swap)
• Detailed Memory Information & Analysis
• Autorun
• ​Swappiness kernel parameter set
• Easy foolproof use (1 click optimization and automatic calculation)
• Supporting Tung all Android devices (root access and Kernelswap support)

You will need a class 4 SD card at a minimum, but for best results you should use a higher class. Almost all the latest smartphones came up with hybrid SIM slot where either you can use two SIM card or one SIM card and a external memory card at once. So in this case if you have free at least 4  G.B. of internal storage then you can use it as virtual memory and enhance device performance.

You just need to root your device.

After successful downloading the app you need to create swap file.

It will take a lot of time to complete, all depends on your built in RAM and processor capacity.

Now you are all set to use your device with increased RAM and better performance. It really helped me a lot hope it also helps you guys..
