52%. That's the number of us who have NEVER wiped their smartphone clean. I'm not talking about trying to remove dirt and grime. I'm talking about wiping information or attachments that you don't want others to see. Apparently, I have friends who send the kinds of things most people don't want to see. I'm fairly certain I delete items from my phone daily. Some things are rude, others are crude and my wife wouldn't find either of them amusing. So I clean. Maybe it's time you did the same?
