How much does your phone's home screen say about you? A lot, apparently. And if you are a Millennial, you really care about what that home screen says. According to a study, 21% of Millennials have deleted an app in the past year because they didn’t like how it looked on their phone or tablet’s home screen. By comparison, just 2% of Gen Xers and 3% of Baby Boomers cared what was on their home screen or what it said about them.
