Once you get your phone, there are lots of great apps to start with! Here are a few:
360 security
360 launcher
Zedge (get ringtones , live wallpapers(animated wallpapers), and wallpapers
While 360 launcher does have ads first launch, you can remove them in a similar fashion to ios, but instead of clicking an x you drag it to a trash can.
Last thing to know is the app drawer. The
🙂:

icon leads you to this. It's like the ios interface. This is how you add apps to your homescreen and also uninstall apps. In 360 there is something called "single mode" which makes the interface like ios, but locks out a lot of features. If you're confusedconfused with anything, I say your best bet is messing around. Everything is pretty easy to use and easy to find! I also swapped from iPhone to Android, and I'm not going back.
Hope this little guide helps!
