512 MB of RAM is not typically considered to be enough for a smartphone. More RAM lets us keep more apps and processes open in the background. This keeps the device from slowing down. Most people think a smartphone needs at least 32 GB of storage. The I4 has only 4 GB. We can expand the internal storage (4 GB) with a compatible microSD card.
