Customization
Customization is what Android is all about. Rather than being this huge operating system that requires you to have your phone in a certain way, with specific apps, Android is bare bones and open for you to customize as you wish. If you want to change the launcher of your Android, you’re more than welcome to, providing you with a plethora of new layouts and features to keep your phone feeling fresh.
On the other hand, iOS is very much you get what Apple gives you. Yes, you can change your background and personalize the vibration feedback of your home button in the new iPhone 7, but other than that, if you get tired of the way your iPhone looks, you can’t do much about it.
Android is the clear winner for anyone who is looking to customize just about every aspect of their phone.
