Archos have taken their big screen Archos 50c Oxygen to UK shores at an attractive £179 price point.
What you get with the Archos 50c Oxygen is an octacore MT6592 processor running at 1.7Ghz, plus 1GB RAM, 8GB storage and a 5-inch 1280 x 720 IPS display. The phone comes unlocked for UK 3G carriers, but lacks 4G LTE, and ships with Android 4.2 rather than Android 4.4 Kitkat. Still for an unlocked phone it is still quite a good price considering dual-SIM support, a micros SD card reader and thin 7.64mm body.
In addition to the Archos 50c Oxygen there is also the more affordable Archos 50b for £129 with quad-core processor and slightly thicker body.Source ]
