ROEHSOFT RAM Expander is an application for Android devices that allows you to increase the RAM of your smartphone. It is designed for devices that initially have a small amount of random access memory. The enlarging occurs by creating a special swap file on the SD card.


To run the RAM Expander, you must have root access on your device. This can be done, for example, using the Towelroot utility. It also requires the BusyBox application and a firmware kernel that supports swap.
In addition, it is desirable that the used SD card has a class of at least the eighth. In this case, there will be no performance degradation of your smartphone.

How it works

The utility creates a swap file on the SD card that simulates the operation of RAM. Due to this, games and applications that require a large amount of memory run faster and easier.
In addition, the freezing of utilities running in the background is stopped. This allows you not to terminate their work forcibly.

Launch and opportunities

At the start, the app offers you to select the interface language. Next, you need to specify the path to the memory card in a special window. You also have to choose the size of the swap file. It is hardware-limited to four gigabytes, but it is undesirable to set the maximum numbers for more stable operation.
Further, you can start creating the swap file. The utility will notify you when it is generated. After that, you may run desired games and apps.
