Hardware & Specification

The Indian Version of the Samsung Galaxy S4 comes with a Exynos 5 Octa chipset. It is powered by a 1.6 GHz Cortex A15 Quad core processor and a 1.2 GHz Cortex A7 quad core processor. It comes with 2GB RAM and 16GB internal storage. Thought the storage can be expanded by using a microSD card but still if users want they can opt for 32GB or 64GB variant of the Galaxy S4. One of thing worth mentioning here is that out of 16Gb only 8.9 GB is actually user accessible. This is due to the fact that TouchWiz UI and other preloaded apps take a lot of space.


The device is quite powerful and it scored over 27,000 in Antutu benchmark and over 13,000 in Quadrant standard benchmark Test. Here is a small video of the various benchmarks we ran on the device.

One of the best ways to test the performance of any device is by playing games on it. We played lot of games on the Samsung Galaxy S4 to test its performance and gaming experience. Here are the videos of the same:

After checking out the above videos I am sure that you would be convinced that Galaxy S4 is a very powerful device and it can handle all your games and apps with ease. Samsung Galaxy S4 comes with 9 different kind of sensors. These are:

  • Gesture Sensor
  • RGB light sensor
  • Proximity Sensor
  • Hall Sensor
  • Gyro Sensor
  • Accelerometer
  • Barometer
  • Geomagnetic Sensor
  • Temperature and Humidity Sensor

The phone also has a IR led which allows the users to use the S4 as a remote to operate various items such as TV, AC etc. In short company has given everything in Galaxy S4 in terms of specs which people usually look for in a smartphone these days.


Samsung Galaxy S4 runs on latest Android 4.2.2 Jelly Bean OS along with Samsung TouchWiz UI on top. The TouchWiz UI is more or less same as we have seen in previous Galaxy Devices.


 The device comes with lot of features and a user can discover new features everyday. The phone comes preloaded with few useful and innovative apps such as WatchOn, Optical Reader and S Health. The WatchOn app allows you to use your mobile as a remote to control your TV and other devices. S Health is an health monitoring and tracking app.


 The S health app allows the user to input their weight & height and then suggest them various ideas to achieve the ideal weight.  Users can also access the Comfort level option in the S Health which measures the current temperature and humidity levels.


The optical reader app allows the users to read a text via the camera present on the S4. Moving on to the other features, S4 have various motion and gesture related features listed under 5 different categories – Smart Screen, Air View, Air Gesture, Motion and Palm Motion. In Palm motion the device allows you to capture a screen shot by swiping your palm over the screen.

The Air view offers user some useful features such as Webpage Magnifier, Information preview, Progress preview etc. Talking about the Air Gesture, it offers features such as Quick Glance, Air Jump, Air move, Air call accept etc to the users. All these features are not equally useful, users would find some of them to be useful while rest may appear not so useful to them.


Smart screen allows the user to turn on/off the features such as Smart stay, smart scroll etc. Smart scroll is a cool feature where users can scroll the webpages by the movement of their eyes.


So if we just talk about the software, Samsung Galaxy S4 does not lack anywhere. It has plenty of fun and useful features.


Samsung Galaxy S4 comes with 13 megapixel back camera with LED flash. The camera offers tons of features and modes. It has some innovative modes such as Dual Shot where you can take a picture from front and back camera simultaneously, Sound & Shot which allows the user to capture up to 9 seconds of sound with an image, Drama Shot, Eraser and much more. Here are few sample images captured using the 13 MP camera present on the Galaxy S4:

The camera can record full HD videos and here is a sample video recorded using the Galaxy S4 Camera:

The quality of captured images is pretty impressive. The images captured in the Day light are very good but this is not the case in low light conditions. The images in low light conditions are quite good but not as impressive as few other smartphones available in the market.

Battery Life

Galaxy S4 comes with a 2600mAh removable battery which gives the device a rated talk time of around 17 hours on 3G. The battery can last easily for a day or two depending upon the usage.

We used the phone for entire day and still had around 28% battery left in the device. During the day we made few calls, played videos, browsed internet, downloaded apps and much more. For a normal user the device can easily last for two days which is quite impressive.


Samsung Galaxy S4 is available in India for Rs 41,500 which might look bit pricey but it is still less than few other flagship devices from various companies. Here is a video overview of the Samsung Galaxy S4.

The phone has a gorgeous 5 inch full HD display and it has powerful specs capable of running any app or game on the device. The phone comes with latest Android 4.2.2 Jelly Bean and has lot of useful features available for the users. The camera and the battery life is also quite impressive. Overall, it is undoubtedly one of the best Smartphone we have ever seen.


  • Beautiful Display
  • Powerful Specs
  • Good Camera
  • Supports microSD card
  • Great battery life


  • Only 8.9GB is user accessible out of 16GB

The device doesn’t really lack anywhere, the only downside we found in the Galaxy S4 is the low user accessible storage. But this is due to the fact that Samsung Galaxy S4 comes preloaded with TouchWiz UI and some apps such as S health which takes up lot of space. But the good thing is that it supports microSD card so you can easily increase the storage space.
