Apple iPhone 7 reviewApple iPhone 7 review
The Apple iPhone 7 keeps the same look as the previous model, but is now water-resistant and comes in a Jet Black colour option. The iPhone 7 is faster, with more memory, a better camera and longer battery life, but the price has gone up again. Oh, and the headphone jack has been removed.

Apple iPhone SE reviewApple iPhone SE review
The Apple iPhone SE gives you the power of the latest iPhone 6s in the compact and stylish body of the iPhone 5s! It's a winning combination, and the fact that this is the most affordable iPhone for years makes it a top buy. We love the ultra-premium & ultra-lightweight design, the super-fast M9 processor and the brilliant iSight camera with 4K video recording. The only room for improvement is the non-HD screen.

Samsung Galaxy S7 reviewSamsung Galaxy S7 review
The Samsung Galaxy S7 launched in the UK on 11th March. Building on the Galaxy S6, the S7 features an all-metal water-resistant design with a 5.1 inch Quad HD display. It uses Samsung's new super-fast 8-core Exynos 8 processor, and includes a microSD card slot, allowing the memory to be expanded to 200GB. A new dual pixel camera enables even better low-light photography, and the new selfie flash lets you capture perfect shots of yourself and your friends. An enhanced 3,000mAh battery keeps the phone going for longer. The S7 is already priced very competitively for a flagship phone, and we don't hesitate to recommend it.

Samsung Galaxy S7 Edge reviewSamsung Galaxy S7 Edge review
The Edge version of the Samsung Galaxy S7 launched in the UK on 11th March. Although it costs 100 more than the standard S7, it offers a larger screen - 5.5 inches instead of 5.1 inches. And of course, the screen is curved at the left and right edges, making the Galaxy S7 Edge the best-looking smartphone of 2016, in our view. With an 8-core processor, expandable memory, superb new camera and a monster battery, it's arguably the best phone all-round.

Samsung Galaxy A3 (2016) reviewSamsung Galaxy A3 (2016) review
The Samsung Galaxy A3 2016-edition is probably our favourite mid-range phone! We doubt that you'll find another compact premium handset this good for less than 300. Sleek metal-and-glass looks give the new A3 killer looks, and it packs in a high spec too - a HD AMOLED screen, a fast quadcore processor, and strong battery life.

Samsung Galaxy S6 reviewSamsung Galaxy S6 review
The Samsung Galaxy S6 brings premium metal-and-glass looks to Samsung's winning formula of a high-spec Android smartphone. The S6 features a stunning quad-HD AMOLED screen, an 8-core processor, enhanced cameras, Android Lollipop and a wealth of other features. The only things holding it back are the lack of expandable memory, and the rather average battery life.

Sony Xperia X reviewSony Xperia X review
The Sony Xperia X is a high-end smartphone with a sleek, minimalist design. Boasting a 23 megapixel camera with hybrid autofocus, and a front-facing 13 megapixel camera, photography is a key strength. But the X is a solid all-rounder - fast, capable, and affordable.

Sony Xperia XZ reviewSony Xperia XZ review
The Sony Xperia XZ is Sony's flagship phone for 2016. Slim and sleek, the XZ is a premium-build device running Android M and featuring a fast Snapdragon 820 processor with plenty of memory. Photography is a key strength too, thanks to its 23 megapixel camera with laser autofocus.

Samsung Galaxy J5 reviewSamsung Galaxy J5 review
Samsung's affordable and popular Galaxy J5 is a mid-range smartphone with a very attractive slimline design and good performance. Its best features are its impressive HD AMOLED screen, decent camera and outstanding battery life.

HTC 10 reviewHTC 10 review
The HTC 10 introduces a new style for 2016, but one that makes it look much like a Samsung - at least from the front. It's a beautifully crafted phone, but not one that offers distinctive looks. Inside, it's a high performer, with a Snapdragon 820 processor, good memory, a USB Type-C connector, and an impressive Quad HD screen. The front camera is superb, although the main camera doesn't match it. It it was priced more competitively it would earn a 5 star rating from us here at S21.
