Kazam Tornado 348 review – The world’s thinnest phone.

The Tornado 348 certainly has the better screen, however. The 4.8in AMOLED display produced much more accurate colours than the Honor 6, covering a full 100 per cent of the sRGB colour gamut. Perfect 0.00cd/m2 black levels gave the display a much higher level of contrast.

It’s also surprisingly bright for an AMOLED panel, as we measured a peak brightness of 320.73cd/m2 when we enabled the phone’s High Brightness mode. This will obviously drain the phone’s already mediocre battery life much faster, but it certainly adds a little extra punch to its already rich and vibrant colours. Without the high brightness mode, the phone’s white levels dropped to 242.12cd/m2, but this is around what we’d normally expect to see from an AMOLED display.

We’re not big fans of the Tornado 348’s rear 8-mgeapixel camera, as all of our outdoor photos had a distinct blue tinge to them, even on a bright sunny day. This really spoiled our shots, and the sensor also struggled to replicate areas with more intricate details. The brickwork in one of our test shots, for instance, was very blurry in places, and bright patches of sky and other white, reflective surfaces were severely overexposed.

Our images improved when we enabled the phone’s HDR mode, as lighter areas of detail became much more pronounced and highlighted against its darker surface area, and clouds and the sky returned to normal, more natural-looking hues. All of our images still looked very blue and cool, though, so colours didn’t look any richer or more accurate.

^ The HDR mode has a distinctly cool, blue sheen 

Indoors, the blue sheen seemed to disappear, but there was a lot of noise in our still life test. Shadows were speckled with rainbow effects and the different textures of our toys were completely lost in the low lighting conditions. Even objects that were relatively well lit looked soft and blurry round the edges, although enabling HDR did help to pick out some of the lighter details and textures. However, HDR also made all the noise appear much more pronounced and grainy, giving our photos an artificial and brittle look, so we’d recommend keeping it turned off indoors.

The Kazam Tornado 348 may be a world-record holder, but its sub-par performance, mediocre battery life and poor camera certainly hasn’t blown us away. We like the design and svelte chassis, but there’s little else to recommend it when the Huawei Honor 6 gives you so much more for the same price. Alternatively, if you don’t fancy Huawei’s Emotion interface and you’d rather have a pure Android experience, then you can still pick up a Nexus 5 for around £270.
