Android devices are known for their fast performance, but they can also suffer from low RAM. This can be a problem if you need to store large files on your device, or if you need to run multiple applications at the same time. To free up RAM on Android devices, you can use a number of methods. One way is to clear out your cache and data when you first start your device. Another way is to uninstall unnecessary applications. Finally, you can try using a memory booster app to increase the amount of RAM your Android device has.
