So Many Apps

It has been only like less than 1 week I'm using Android Phone and the problem is there are so many apps to explore..and I really dont have the time to explore it one by one..anyone can help? It's a good laugh.

                          Facebook, viber, instagram..easier..the rest need to explore..

Another thing is that I need more time to explore my S3. Totally a new thing to me..Anyone who is a real expert in S3, please teach.
