'Something completely new for the Lumia 640 is a front-facing camera.'

'Large 5-inch screen'

'It’s disappointing that Sony hasn’t matched the Z3’s Full HD display, but this is still good for a phone this size, and it matches what the competition currently offers.'

'The Sony Xperia Z3 Compact packs a larger screen than its predecessor in the same size body, it has tonnes of power, it's completely waterproof allowing for underwater photography and it has a good camera.'

'fairly sharp picture'

'most comfortable and premium Sony Xperia flagship'

'High-end specs.'

'Dust- and water-resistant'

'Slick overall performance'

'With decent hardware and a price tag of around ?300, it is a solid phone. '

'It will feel comfortable to most users and the Xperia M4 Aqua is very thin and light for a mid-range phone at 7.3 mm and 136 g.'

'The G3's flagship feature is its 5.5-inch, 2,560-by-1,440 screen—the highest resolution you'll see anywhere. '

'Improved interface'

'The slim screen bezels and tapered edge design also help the LG G3 feel reasonably trim when held. '

'It's unsurprising that performance is smooth and nippy the vast majority of the time.'

'It's the best equipped smartphone in the Lumia 640 series - it packs a massive 5.7" screen and a 13MP camera. '

'You also get 1080p video capture on both the front and rear cameras, with good results. '

'The aperture is of the G Lens camera is reasonably wide (f/2.0), which should also help the camera achieve good results in low-light conditions, as it lets more light reach the sensor.'

'Great screen.'

'Improved screen contrast and angles'

'The Xperia Z2 is packed with the latest wireless technology so you'll be sorted with dual-band Wi-Fi up to 11ac, Bluetooth 4.0 with aptX, NFC and 4G LTE are all on-board. '

'Thanks to the arched nature of the phone, it ergonically contours in our hand to provide a natural grip. '

'The build quality is close to top notch and it really does feel like a smaller One M8, although I did find the nanoSIM tray on the left of the device didn't sit completely flush with the case.'

'Design.'

'HTC has taken a minimalist approach when designing the Desire 816.'

'The 720x1280 resolution might be stretched thin over the 5.5in screen, but the resulting 267 pixels-per-inch is dense enough to deliver a solid viewing experience.'

'Footage is smooth, but again, you lose some detail in low light.'
