One of the differences between hardware and software when it comes to smartphones is that with hardware you at least know what you’re getting.

The manufacturers that own the many different smartphones out there that run Android do have some sense of order, but you’ll never know exactly how many software updates are going to be in store for your device.

If there ever comes a time when you’re no longer satisfied with the version of Android that you’re running, and you wished that you could update the device to something newer, that’s the time you want to go searching for custom ROMs.

These are the best custom ROMs for the Samsung Galaxy Mega smartphone.
