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.

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

worked for a few minutes, then freezes up. tried everything, downloaded updates, removed battery, to no avail will be returning it

Verdict Great phone two years ago, but other models offer lighter, larger more innovative models

Powerful hardware; quality screen; great camera

Plastic cover; confusing features; lack of standout features that are truly practical

Purchased this phone not even a month ago (day it came out) and have had problems ever since. Lags continuously, fast battery life, deletes messages you're writing right before your eyes, constantly runs apps which you've given no permission to run or you've forced close (which you ALWAYS have to do...

camera; bright colourful screen

slow processor, lags constantly, short battery life, pointless software, always running apps when you force close, bad reception; especially in regards to internet

Had to replace battery one week after being.phone kept saying can't find SIM card then shut off.city compatible to certain apps which is very strange.I can't download certain simply apps from play store keep saying my device is not comparable .

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.

Great phone for the money. Very easy to use and set up.

Phone is delivered before the given time. Packaging is very good. The phone is very good and light weight. Multiple extra and new functionality in this. Good internal memory. Don't think there is too much heating problem.

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.
