Mark's son has an 8GB Samsung Android phone. How can he make more room on it? Leo says to do a factory reset. That will wipe the entire phone and leave just the operating system. From there, he'll have a good idea of how much room that phone really has on it. It won't be much. Apple doesn't sell 8GB phones anymore, neither do most of the Android makers. They're about to dump 16GB models as well.
