Microsoft Lumia 640
Housed under the brightly-coloured case is a quad-core 1.2GHz Qualcomm Snapdragon 400 and 1GB of RAM.
Both keep the tile-centric operating system running smoothly.
Measuring just 8.8mm, the Lumia 640 may not be quite as svelte the latest flagship phones but still cuts a trim figure.
The glossy plastic back is removable – revealing access to the Micro-SIM, MicroSD and interchangeable battery packs.
The handset supports MicroSD cards up to 128GB and will likely be an essential purchase for Lumia 640 owners, since the phone itself only has a meagre 8GB of internal storage.
Fortunately, you won’t have to spend much time swapping battery packs in the Lumia 640 as the battery life is excellent.
The budget smartphone comfortably endures a couple of days of heavy usage before forcing you to reach for the MicroUSB cable.
Microsoft should be congratulated for the display on the budget Lumia.
The five-inch screen – which boasts an impressive 294pixels-per-inch – is colourful and crystal clear compared to other smartphones in the price range, like the budget Sony Xperia E4.
