'Tis the season of own-brand device launches, it seems. A couple of weeks ago, EE announced its new range of in-house products, including two smartphones, and today it's Vodafone's turn to show what low-cost hardware it's been cooking up of late. Joining last year's Smart 4 power/turbo handsets and the more recent Smart 4 max is the new middle child: the Smart prime 6. With a 5-inch, 720p display, 1.2GHz quad-core Snapdragon 410, 1GB of RAM, 8 gigs of storage and 8-/2-megapixel cameras, it's not the most exciting of devices. That said, it's 4G-ready, loaded with Android 5.0 Lollipop and comes in at £79 on pay-as-you-go, or free on contracts from £17 per month.
