The main highlight of Tecno Spark 4 Air is its 3 GB RAM. Most phones around this price range are offering 2 GB RAM so, it is a big plus. However, the 2.0 GHz quad-core CPU, the MediaTek chipset used in this device are not that fast. Moreover, Tecno&rsquo, s current HiOS UI isn&rsquo, t the best in the market in terms of software optimization. So, multitasking and regular app usage should be fine, but big games like PUBG wouldn&rsquo, t run super smooth. It is, however, playable in low settings. Both 5 MP front and 13+2 MP dual back camera quality is satisfactory considering the price. Daylight shots are reasonably fine and night-time shots can be captured with the flash to get better lighting. 6.1 inches dot notch HD+ display with the mysterious kind of gradient back made this device an attractive looking one. There is also a fingerprint sensor on the back, which is stylish, practical and ensures much better security. There is also a face unlock option. The phone has 32 GB of internal storage, which is also excellent. But one disadvantage of this phone is its 3000 mAh battery. Many phones are offering batteries as big as 4000 mAh around this price. 3000 mAh is slightly behind in the competition. Although, the light and optimized HiOS of Tecno should make it go though a full day.
