Samsung has the worst customer service EVER. Don't buy S4 or any other expensive device from Samsung.  I had S4, which has charging issue, sometimes it takes 10-12 hours to complete charge the battery. It has been 5 months issue is still not resolved and mobile is only 6 month old.

Is the Samsung Galaxy S4 the best phone out there right now? In many ways, yes. It's ‘smarter', it's more powerful and it'll last longer than the rest. Smart features like Air View and Multi Window work well and the 1.9GHz processor, stunning screen and great battery make the Galaxy S4 a gamer's...

Stunning screen; Powerful and innovative; Fantastic battery life; Strong camera in good light

Glossy plastic construction; Heavy interface; Occasional UI stutter; Mediocre low-light camera

Comparing to Galaxy S3 it has better camera but battery drains faster and price is higher. Also had some connectivity issues when turning airplane mode on and off. It shows that airplane mode is off and shows full antenna bar however I couldn't make any calls and there was no internet.

The much anticipated Samsung Galaxy S4 smartphone has now been out for a couple of months. Here's where we find out whether the flagship Samsung phone is still head and shoulders above the rest of the Android market, or if other smartphone manufacturers have caught up.

Canadian version is Quad Core with 2GB of ram, which is different spec'd than this international version.

-Screen (Large; HD; Gorilla Glass 3) -Fast (Processor and RAM) -Great camera features (panorama; beauty mode; motion pictures; front and back simultaneous capture) -LED indicator -Hardware buttons -Great battery life (1 day of moderate usage

-All plastic (nice to be some metal) -Samsung TouchWiz UI is sluggish compared to stock Android -Android updates are slow; still no 4.3 as of 10/29/2013 -Camera could be faster (compared to iPhone 5

The phone has an awesome screen Comes with too much bloatware(does take some time to clean it up) The battery life is about as long as you would expect from a 5" display phone this thin(1 day if you don't use it too much)

Nearly half a year after its initial release, the Samsung Galaxy S4 ($199.99/16GB with 2-year contract) remains a top option on every carrier it's available on. The blinding number of features and impressive performance keep the S4 at the front of the pack.

Dizzying number of features; Incredibly fast; Ships with Android 4.2.2; Relatively small for its display size; Spectacular call quality

Limited storage on 16GB model; Low-light camera performance could be better

Samsung Galaxy S4 is the latest addition in the Galaxy series from the South Korean manufacturer. Hoping it to be the best selling smart phone in the market, Galaxy S4 was released as a worthy successor to the mighty S3.

Impressive HD screen; Great performance; Good battery back up; Impressive camera; Dual shot camera

Unimpressive design; Poor low light camera shots; No FM

S4 really suckz.. My friend just bought it 3 months back and already we have given it thrice to the service center. Motherboard has already been replaced. There is a manufacturing defect with the phone but they never accept it.

The phone exceeded my expectation of a smartphone and had all functions I needed. Though the battery can get a little too warm when watching videos on the phone.
