At one point, HTC
made the best Android smartphone; at another, Samsung held that title.
The mobile giants step back into the ring for another round, as JavedAnwer referees the fight between the Samsung Galaxy S4 and the HTC One.

If you are using a smartphone older than one year and feel you need
better performance and features, both Galaxy S4 and HTC One are good
options.
The Galaxy S4 boasts some nifty software features. For example, Multi-window allows users to work on two apps in a single screen. Not all apps support this feature, but it's available for a few important ones such as Gmail, Chrome, Twitter, Messages and Youtube. Then there's Dual Shot, which allows a user to superimpose his stamp-sized image taken from the front camera on a scene shot with the rear camera. S Health is another feature that stands out. It allows a user to monitor his physical activity like walking or jogging throughout the day, and also shows the actual temperature and humidity in his surroundings. However, some features don't work as consistently as we would have liked, such as Air View, which allows a user to preview images without even touching the screen, and Air Gesture, which allows a user to take a call with a swiping gesture above the device. Still, the features that work are enough to make the S4 a more useful and handy device than other smartphones. Besides, the S4 allows for interchangeable batteries and expandable memory via a microSD card.
