Only because we have no option! But to try and find where settings etc are, I often have to open and close several icons before I finally open the right one! Of course, that is obviously only because I am ancient. LOL. No, it isn't because I have watched my very phone-savvie daughter do exactly the same thing on many occasions! Why? Because some of us have far too many things to try and remember already, without having to try and remember what's under every icon on a mobile phone!
