Swapper for Root is an advanced tool for Android devices which allows you to manage your device's swap without creating / managing a swap partition on SD card. To use this app, your device must be rooted as well as the kernel swap support is required. Swap size can be configured according to the need. The default value is set at 60 and it can be increased up to 100 when required. You need to download Swapper for Root APK file to install it on your device or you can install the app from Google Play Store also.
Remember that Swapper for Root manages swap without any SD card partition. So neither it creates any partitions on your device's SD card nor it manages an already created one.
