Choosing the right smartphone can be really time consuming. Some customers tend to second guess their choice even after a buy. A little bit of research about the smartphones in the market should help customers choose better. To those who have narrowed down their choice between the Samsung Galaxy S4 and Sony Xperia Z, here is a comparison.

To those who want a bigger 5 inch screen phones both the S4 and Xperia do not disappoint. They both come in a 5 inch screen, 1080p. The other specs that are similar are the camera and RAM. Both the cameras have a 13 MP camera at the back and a 2 MP camera in the front. Both come with a 2 GB RAM.

Now for the difference - the S4 comes with 1.9 GHz quad core processor and runs on Android 4.2.2. The Xperia comes with a 1.5 GHz quad core processor and runs on Jelly Bean 4.2.2.

The Samsung Galaxy S4 comes in a plastic body whereas the Sony Xperia Zcomes with tempered glass which is scratch resistant and water resistant. The Xperia can be submerged in water with a depth of about one meter depth for about 30 minutes. The S4 comes on all the major carriers in the U.S, where as Xperia Z which is available on T- Mobile has a lot of catching up to do.

The S4 has some unique and interesting features like the "AirGesture" where the user need not touch the phone to perform tasks like flipping through a photo album; a simple wave of the hand near the phone will automatically flip the photos. The other feature in S4 is the "Group play." This is a great socialising tool which allows the user to share and coordinate activities with other S4 users.

The choice between the Samsung Galaxy S4 and Sony Xperia Z comes down to personal taste and preference. People who are impressed with features of the S4 can opt for it. But for users put off by its plastic design, the sleek Xperia Z is the better choice.
