Lenovo has launched two new entry-level smartphones, setting a new standard for features and affordability. The 4.5-inch Lenovo B is lightweight and compact and provides quad-core performance for essential web surfing and media at 4G speeds. It has TFT-TN display, rounded edges and a textured back cover, so it feels great in the hand. IT carries an RRP of £79. The Lenovo A has similar features but with support for 3G only and at £69 is even more affordable.
