So here is my verdict on Android after using it for personal use now for a few weeks. If you use the native Google Apps, which there are many of on the Play Store; my experience has been the best on a smartphone next to iOS. If you use any of the Samsung Apps, it is horrible....
Samsung has built proprietary apps and even have there own app store for there phones. There apps are only designed to run on Android OS so why have your own store? Well I will tell you why Samsung is attempting to pull an Apple. Get you to love there apps which are only tied and usable on there phones.
Here is the deal why would I buy a Google Android OS phone and load Samsung Apps on it, that can't even touch the Google experience.
We are talking about from the keyboard, the launcher, the widgets, the texting app, the photos app, the health app, the music app, the web browser, etc... etc...
Google developed apps run much smoother on Android OS and that is the way it is intended to be. I love Samsung's hardware especially this S7 Edge but the OS and Apps go to Google, hands down. (Ravi)
