Samsung Galaxy S5 vs Galaxy S4: Do you need to upgrade?

We investigate whether the 2014 handset is a must-have

The S5 has some unique hardware features which help it to stand out. As already mentioned the latest smartphone has a better camera and is waterproof/dustproof. Here we look at three more features exclusive to the S5.

Heart rate monitor

A sensor on the back of the device allows users to measure their pulse with a finger. Although a useful indicator for health conscious users, it's limited to use before and after exercise. The heart-rate monitor is a good example that shows the stagnation of the smartphone market as vendors scramble to find features to add.

This is included on the home-button and allows users to log into the device with a swipe. Samsung has also teamed up with PayPal, so users will be able to authorise payments with this feature.
