This trick involves creating a partition on your SD card, which will act as a secondary source of RAM. To do this, you will first have to check if your device is compatible with the app. By downloading MemoryInfo & Swapfile Check here .Start the app and give it SuperUser rights. Click ‘start ramexpander test here’ at the bottom of the screen. Select the SD-card or Ext SD-card. Then press ‘Click for result’. If ‘Congratulations’ appears, your device is compatible with the RAM expander app!
Install the ‘Swap’
If you have a compatible handset, download and start the ROEHSOFT RAM-EXPANDER (SWAP) app and start the application. Give it root permissions and select your language (you can choose English, German or French).
Use the slider to select the amount of space you want to allocate to your SWAP partition. Tap ‘optimal value’ to automatically adjust the settings for the best performance, and ‘autorun’ should also be enabled. The last thing you need to do is tap ‘Swap Activ’ to complete the process.
Your system should now have more RAM, and thus better performance, thanks to the support of your SD-card. (Note that this process will mean that the SD card is no longer accessible from a computer.And also make sure you use an SD card with enough space! Atleast 4gb.)
