    Take pictures like a pro

    Whether you're trying to capture an evening selfie, a cityscape or a distant landmark, nothing's ever too dark, too vast or too far away for the Galaxy A9's incredible Quad Camera. Whatever the environment you're shooting in, you'll get crisp, bright photos every time. With an optical zoom, ultra-wide lens and superb low light capability, you'll never need your digital camera again. And you'll look like a pro, as the camera's Artificial Intelligence automatically selects the best setting for the scene.

    See and hear things clearly

    Watch movies, show off your photos and relax with the latest games. It'll all look just as it should with the Galaxy A9's 6.3-inch, Full HD Super AMOLED display. But looks aren't everything. Thanks to the Dolby Atmos speakers, you'll enjoy great sound too.

    Get power and security

    Home's busy. Work's busy. Life's busy. So you need a phone that can keep up. With a powerful processor, plenty of storage and a large battery, you can be sure that the A9 won't let you down. And you can rest assured that your photos and content will stay personal, with a fingerprint scanner and facial recognition as security options.

    Keep a personal assistant in your pocket

    Want to call a friend, add a lunch date to your calendar or look up recipes online? Just ask Bixby. Your personal assistant, Bixby learns what you like to do, and when, and works with your favourite apps and services to help you get more done.
