Asus Zenfone 4 which was released a couple of months ago with Android 4.3 KitKat OS out of the box, can now be updated to Google's Android 4.4 KitKat via the over-the-air (OTA) mechanism.
Asus Zenfone is a typical value-for-money smartphone, and the device has seen two other iterations, viz Asus Zenfone 5 and the comparatively high-end Zenfone 6.
With the Asus Zenfone series accumulating devices right from the basic to the high-end, Zenfone devices compete with a range of smartphones having similar hardware aspects and pricing.
Most prominent among competing smartphones include the recently launched Vodafone Smart 4 Turbo and Smart 4 Power devices that are priced within the £150 bracket.
Also, other prominent smartphones like the Moto G and EE Kestrel (both devices are considered to be feature-filled and affordable) compete with Asus Zenfones.
However, the latest Google Android 4.4. KitKat operating system update is confined to only the Asus Zenfone 4, and is not available to users of Zenfone 5 and Zenfone 6 smartphones.
Classified as an 'affordable' smartphone, the Asus Zenfone 4 is priced at £99 in the United Kingdom.
