Samsung Galaxy S4 is now being released gradually around the world and begins the latest trend of the world's most powerful smartphone ever made. If you want to know more about the handset, check out this 10 secret features unveiled for owners and prospect of the Galaxy S4.

Android Authority uncovered the hidden features of Galaxy S4 and gives owners the chance to maximise the device.

1. Dual Shot
It allows both rear and front cameras to capture images without angling the phone awkwardly. Dual Shot not only captures image but also record videos using both cameras and the best part of this feature is you can use it on video chat, streaming not only you on the front camera but also what the rear camera is aiming at.

2. Eraser
Sometimes, when you take a photo in a busy place such as mall or restaurant, many objects are constantly moving and even people suddenly walks during a photo capture. Erase feature of Galaxy S4 attempts to remove moving objects by analysing the capture for a few seconds.

3. Animated Photo
You can create an animated file image called GIF using the Galaxy S4. It analyses for a few seconds and generates a result of how your animation would look like. The feature is not perfect but good enough to play with.

4. Drama Shot

This feature allows the user to take photos by freezing all other moving objects while keeping the subject in motion. Drama Shot can be tricky and if the subject is too near to the device, it may not work at all.

5. Sound & Shot
Capture a photo and adds audio recording to it. The feature allows you to narrate something about the photo you would like to share.

6. S Health

The application tracks down your diet and your daily eating habits. You can simply edit the profile inside the application and use S Health to monitor your daily exercises, calorie intakes or improve your current healthy activities.

7. Watch On
Use your Galaxy S4 to control TV sets and cable boxes with its Infrared Blaster. Select the Country, Postal Code and the device you want to control on the list provided. Hopefully, Samsung can enlist more devices supported by S4.

8. S Translator
Acts similar to Google Translate which translate words, phrases and sentences between languages. You can either type or send a voice command of what you wanted to be translated.

9. Optical Reader
You use the rear camera to read QR or Barcodes and access details online. You can also translate text imparted on captured images using the Internet.

10. Air Shuffle, Air Gestures, and Eye Tracking
These three are useful if you do not want to touch the screen of your Galaxy S4 as you navigate across applications. You can wave you hand in the Gallery app to view the next image or go backwards, hover your finger over the browser to magnify text and look away from a video playback to pause it.
