The Microsoft Lumia 640 comes as a refreshing change with a great 5-inch display, 4G LTE connectivity and an 8-megapixel camera. That's all wrapped up in plastic shells that are swappable and come in a range of vibrant colours. The standard Microsoft display comes with colourful tiles but the battery life and fewer choice of apps in the app store are the only drawbacks.
