[M] VKWorld VK6735 Smartphone Review
 

VK6735 from VKWorld is another low-cost smartphone which is using the already established VK6735 SoC but at a lower frequency of 1GHz, while sporting the same ARM Mali-T720 GPU. We get 2GB of RAM for running more applications in the same time, 16GB of storage space with a single partition and the possibility to install a SD card makes things more interesting. The VK6735 is dual-SIM and features integrated 4G LTE WorldMode and CDMA2000 3G for global high-speed mobile network compatibility and is also equipped with a Sony 13MP shooter on the back while the selfie camera is 5MP. Of course, the VK6735 also comes with Android 5.1 release pre-installed which is the latest available for the current SoC.
