Samsung Galaxy S4 Android phone

This galaxy S4 is my first Samsung andriod phone and it did not fail me. I have owned for around 2 weeks and playing around with it, when I run the benchmark test it scores 3210. I found it S features pretty useful and 13MP camera with 2.2flens really a great pocket camera with the production of crispy, stunning images and full HD @ 30fps. Built-in 16GB +user expandable memory and user-replaceable battery are handy stuffs also. I find it very useful on having multiple windows effect which is not new. Thanks to 2 GB RAM its application performance loads up real fast and switching between apps is a breeze. All in all, this is a great phone with great performance, I really enjoy having it. Battery life is great if you use the wifi effectively it can last for 2 to 3 days without charging. The 3 main things effect on battery usage 4G LTE network, wifi and screen brightness. So adjust them wisely to crave out the best battery life. I put it +5 on Auto mode in screen, use wifi when I need and use 4G when I need and it can last for a day(merely 24 hour).Cheers!
P.S- My S4 version is I9505.
