I'm going to start my first point by saying this; the Android operating system is very malleable and many changes can be made on Android that are otherwise impossible on an Apple iPhone. (or any apple device for that matter) Icon packs add a certain style to all of your icons, and dynamic backgrounds adds animations to rather bland backgrounds. Also, creating an app for Android is FREE, as opposed to the $100 a year that Apple offers. I have many other things to say, but I will leave them for future rounds.
Well we can also download apps to customize our phones. Also iPhones have the Facetime feature. We don't have to download an app to video chat. There are some things iPhones is better at, and there are somethings Androids are better at.
The point of these debates is for one side to win, not "oh well both of them are good." First off, if downloading Skype or another similar app takes just too long for you, you need give yourself some free time. Also, providing some examples for these customization apps that you claim to have would be great. Just to add some fuel to the fire, I will provide another point: A lot of "new" iPhone features are what Android had years ago. These features include; 4.7 inch screen, HD resolution, Notification actions, third party keyboards (oh look, I just gave you an example), cloud photo backup (quite unreliable), and much more.
The features I have stated are new for the iPhone 6, but were first seen on the Nexus 4 Released in November of 2012.
