http://www.bbc.co.uk/news/technology-43784990 I personally use Huawei. Bit scary now
That was a brilliant deal for that price!
Mine is the 6gb/128gb model, not global as I'm not too fussed about band 20. It cost me £210 from gearbest before Christmas. I have the nationwide banking app installed and it runs fine, NFC and Google pay both work flawlessly
I can't speak for Ulefone, however they seem to be a vastly budget minded company, probably just using cast off components to build budget phones. For the detractors of Xiaomi phones though...I can see Xiaomi hitting the UK mainstream market within the next year. You will soon see them being sold on the UK high street, much in the same vein as Huawei, or OnePlus; who started out as a relative unknown and are now competing with the big dogs. I have bought a few Xiaomi for myself as well as family, and they are solid phones for the cost. They're wildly popular in China, so the quality and expectation of them is a lot higher than most of the other "weirdly-named" China phones. I also read recently that Xiaomi are considering buying the GoPro company, so it's not as if they're a fly-by-night outfit. They are big contenders in the tech market, and gaining more traction everyday.
I have this phone. Really good phone for the price but as metioned the specs are not as good as it is on the paper. But still much better than other phones on the market. The screen is really good and the battery does last 2-4 days depending on use. The camera is not that great but most of the chinese phones are the same. I haven't seen any software glitches so far. It runs pure android and promised to get latest android update. Only glitch I have seen is, when you restart your phone, the shortcuts rearranges itself. I have run many games but works really well. I suggest checking out videos on youtube for battery, camera and speed performance.
