Samsung unveiled new versions of their Galaxy A series - the A3 and A5 - two mid-range phones designed to be more affordable than the company's Note and Galaxy S ranges, as well as the larger Galaxy A7. All three are virtually identical to their predecessors but have minor upgrades as Samsung looks to get back on track. All three devices are water and dust resistant and are designed with a 3D glass back that was used in the Galaxy S7 and Galaxy S7 Edge. They each come with a shiny new USB Type-C port, while the two larger versions have also been gifted with Samsung's Fast Charge technology. The new A3 and A5 phones, which come with 4.7-inch and 5.2-inch displays respectively, will be available to pre-order in the UK from January 20 before a global release. The company is yet to confirm pricing for the two devices. Both the Galaxy A devices are water and dust resistant for the first time and will come with 16 megapixel front and rear-facing cameras. A special selfie mode has also been added that enables users to tap anywhere on the screen to take a photo using the front-facing camera.
