    Introducing the Samsung Galaxy A3

    With a slim, metal body, the A3 can sit comfortably in your pocket. Take selfies and make video calls on the 5 megapixel front camera. Watch movies, play games and much more on the 4.5 inch Super AMOLED touchscreen display. And enjoy quicker browsing and multitasking thanks to the 1.2 GHz processor.


    Slim, light and comfortable to hold

    The Galaxy A3 is Samsung's slimmest smartphone yet. At just 6.9mm and 110.3g, with a full metal unibody design, it's easy to hold and use, and slides comfortably into your pocket, so you can take it with you wherever you go. It also comes with a long lasting 1900 mAh battery, to keep you going for longer.

    Take the perfect selfie with the 5 megapixel front facing camera

    The A3 has a 5 megapixel front facing camera, which means taking selfies has never been easier. Whether you're on your own, or with a group of friends, the A3 has a variety of features to help you take the perfect picture. Wide Selfie, Palm Selfie, Animated GIF, Beauty Face Features, and Rear-cam Selfie all help you get the best from your photos. And you can share them instantly with your friends and family on your favourite social media sites.

    Be entertained on the adaptive Super AMOLED display

    The Galaxy A3 has a 4.5 inch Super AMOLED touchscreen display, which uses Adaptive Display technology to give you clearer images and better viewing angles. So you can enjoy all your favourite entertainment in more detail wherever you are, even in bright sunlight.

    Get all the things that make Galaxy great

    The Samsung Galaxy A3 uses a quad core 1.2 GHz processor. So you can enjoy smoother, faster browsing and seamless multitasking, for when you want to flick between your apps, movies, pictures and more. And the A3 includes all the features exclusive to Galaxy devices, such as Ultra Power Saving Mode, Private Mode and Multiscreen. It also adapts and enhances sound output depending on your surroundings, using adjustable audio.

    Why doesn't this phone come with a charger?

    O2 is working to try and reduce waste. And as 70% of people already have a USB charger at home, we've decided to not include one with your phone. If you do need a charger you can add one after choosing your tariff. O2 does not make money from selling the charger separately.
