Motorola Moto G4 reviewMotorola Moto G4 review
The Motorola G4 does everything you could ask of a mid-range phone. Running Android M, it's strongest features are probably its high resolution 5.5 inch screen and its larger-than-average battery. It's water-repellent too, with an 8-core processor, 16GB of memory, and a good camera. Seems like nothing's missing!

Sony Xperia X Compact reviewSony Xperia X Compact review
The Sony Xperia X Compact is a high-end compact smartphone with a fast processor, outstanding camera and plenty of memory. Lightweight and easily pocketable, it offers most of the features of Sony's flagship devices. However there are a few compromises and it seems over-priced compared with the alternatives.

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.
