'While I may not be entirely sold on the design changes, using the Z5 Compact has been great. '
'The processor inside is a Qualcomm Snapdragon 810 which is a nice upgrade from the Z3 Compact which has a Snapdragon 801.'
'Elegant, waterproof design.'
'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'
'Very heavy Android skin.'
More storage, more power, more megapixels – for a lot more money
A mid-range phone with a decent selfie camera, but its sluggish chipset and mediocre battery life fail to make the Xperia M5 stand out
Shoots 13MP selfies, but is the rest of this phone any good?
'With decent hardware and a price tag of around ?300, it is a solid phone. '
'Video recording quality is bad.'
'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 upper half of the rear of the phone became noticeably hot after just a few minutes of even ordinary use.'
'If you need a good-looking phone in this price range which will last up to two days on a single charge, then by all means consider the Xperia M2. '
'Using a large screen and flashy design means the Xperia M2 can easily pass for a top-end phone at a glance. '
'We found that it could last for two days of normal use between charging. '
'Screen isn't competitive.'
'the sound that came out of its speaker was disappointing and muffled.'
The Sony Xperia M2 Aqua is a new water-resistant version of the original 4.8-inch Android smartphone, great news if you like snorkelling.
'Camera is sub-par, sorely lacking in detail.'
'One other pretty rubbish element of the screen is what it's made of.'
'You need to get around the 300ppi mark to get really good sharpness, and the Moto E does better the Xperia E1 despite its larger screen with 256ppi.'
'It’s not a terrible screen but – you guessed it – the Motorola Moto E offers a much better one. '
'The Sony Xperia Z1 looks stunning, it's a distinctive design and there's no questioning the quality of the build. '
'For normal media viewing everything looks great, but you really notice the difference when watching or viewing full HD 1080p content where, as with the Xperia Z, everything takes on an incredible and cinematic, almost 3D-like quality.'
The next level of Sony's Android ambitions or a needless mid-cycle vanity upgrade?
