|Microsoft Lumia 435 review|
If you're looking for a smartphone costing around £50, your choices are very limited, but the Microsoft Lumia 435 gives you a lot for your money. It's a dinky phone with a decent screen, a dual-core processor and plenty of memory. The cameras are very poor and the battery life not much better, but it's good as a first phone or as a spare.
|Motorola Moto E 4G review|
The second-generation Motorola Moto E is an entry-level smartphone that offers outstanding value for money. It may lack premium styling, but it has everything else you could want from a budget phone - and more.
|Samsung Galaxy S6 Edge review|
Just when you thought all smartphones looked the same, the Samsung Galaxy S6 Edge brings a fresh new look. Featuring a double-edged curved screen with special edge display features, it's one of the best-looking phones you can buy. It's also super-powerful, with an 8-core processor, outstanding cameras, plenty of memory and the latest Lollipop flavour of Android. But make sure you're sitting down before you look at the price!
|Samsung Galaxy S6 review (updated)|
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.
|Huawei Ascend G7 review|
The Huawei Ascend G7 is a big-screen smartphone that's priced for value. Featuring an ultraslim metal casing, it looks good too. It's top features are its 5.5 inch HD display, outstanding battery life, high-spec cameras and quad-core processor. We rate this very highly if you're after a big screen but lack the budget for a flagship phone.
|HTC One M9 review (updated)|
The HTC One M9 smartphone looks almost identical to the iconic One M8. The UltraPixel camera of the M8 has been replaced by a much better 20 megapixel main camera, and the processor has been upgraded to an octa-core Snapdragon 810. The M9 isn't a great leap forward, but is one step closer to perfection.

|HTC Desire 820 review|
The HTC Desire 820 gives a lot for your money - a powerful octa-core processor, a big 5.5 inch screen and an 8 megapixel front camera. But it's too big to become a mainstream phone.
|Microsoft Lumia 535 review|
Microsoft's first smartphone is the entry-level Lumia 535. Selling for less than £100, or on very cheap contracts, the phone has a lot going for it, including a huge 5 inch display, a 5 megapixel front camera and good battery life.
|Samsung Galaxy A3 review|
The Galaxy A3 from Samsung is a mid-range phone with a premium metal design. It's compact, ultraslim, and exceptionally light in weight, but rather over-priced.
