In my opinion galaxy s4 is the best 1 in this series of samsung s series .perfect in shape and size slim its very comfortable to carry I am using this mobile from last 2 year 'still my phone is in good condition and working good.1 issue I found that when I use more than 3 hours continiously it bocomes heat .and rest everything is good battery backup is also fine.
In all android phones I would recomond this for every one .nice sound quality gokd cameras front and back .good for video calling .superb
