On the one hand it reflects a myriad of features that are embedded in the Galaxy S4. But, on the other hand also shows the number of bloatware aka default application that is not necessarily used in this smart phone.
Applications are consuming enough on-board memory is available. The internal storage of 16GB Galaxy S4, remaining less than 9GB. Fortunately, there are still options to expand micro-SD slot up to 64GB.
One other interesting thing of the Android 4.2.2 operating system is the user can add widgets on the lock screen to access certain functions without having to unlock the device first.

Row of widgets that can be added including cameras, e-mail client, and more. More options can be accessed in the menu "Settings> Lock screen> Lock screen widgets". Written messages displayed on the lock screen can be set as desired.
Special Features of new galaxy s4
One appeal of the Galaxy S4 lies in the ability to detect multiple types of gestures that can be used as an input mechanism than touching a finger on the screen.
By enabling "Air Gesture", users can wave vertically and horizontally in front of the smartphone to navigate without touching laya. Features "Smart Scroll" is used for scrolling web pages by tilting the phone forward and backward. Users can also be tilted and lowered his head to run the feature, as long as there is a change in slope between the eyes with the point of view of the sensor on the Galaxy S4.
Other functions include Smart Stay which is already implemented on the Galaxy SIII. By enabling this feature, the Galaxy S4 detect if the user is looking at the screen and will not dim or turn off the screen while still in use.
Feature is similar to the Stay Smart "Smart Pause" equally detects the user's eye. The difference, used Smart Pause to pause the video playback when the user looked away from the screen. Playback re-done so the user looked at the screen.
Then there are the "Water View" which provides a preview of the content for multiple applications, such as e-mails that can be read without the need to first completely open, just to cast a finger across the screen.

Unfortunately, even a cursory look attractive, gesture detection features of this body has limited usefulness because it is only able to work with specific applications.
Smart Gesture Scroll and water, for example, is only compatible with the default Android browser application. Galaxy S4 only paused when the user waving hands in front of third-party browsers, such as Chrome and Firefox. Air View also can not be used with application Gmail.
Any time can be used, the implementation of some features was less than optimal, such as the difficulty of detecting Smart Scroll view when the user is wearing eyeglasses. Gesture water can be useful at certain times when the user can not touch the screen, such as when the hands are covered in food. However, swinging arm eventually did make sore.
Even though it looks cool, in the end the features unique to the Galaxy S4 was less useful than the conventional way of interaction with the touch screen. Of course, users can turn off these extra functions whenever an undesired. It can be a little help in saving battery.

The high performance S4 Galaxy must be paid with a few things. This device quickly feels hot when invited to play games or record a video. The heat spread to the screen and interfere with comfort.
