Oukitel K4000 review and unboxing

This handset is heavy but for its size it is comfortable to hold. Power button and volume rocker is on the right side, micro USB port is at the bottom and audio jack is on the top. This is a dual SIM handset – 2 x micro SIM slot + a micro SD card slot.

This handset is powered by MediaTek MT6735 64 bit quad core processor clocked at 1GHz coupled with Mali T720 GPU. Overall performance was smooth and lags free.


  • Quadrant – 9297

  • Nenamark 2 – 50.4fps

I played Asphalt 8, game was playable in high visual quality mode but not very smooth, it did well in medium quality mode. The game got installed on the external storage.

There is 13MP primary camera with flash and 5MP secondary camera. Rear camera can shoot 720p videos. Handset however can play FHD videos. Camera quality is average, check the sample images and video listed at the end of this review.

Sound is loud and clear. In-call sound is also good, no issues with networks. This handset supports 4G however 2300 band is not supported. 3G, WiFi, Hotknot, Bluetooth and GPS worked well.

The handset is tough and screen is scratch resistant to a larger extent.

The Oukitel K4000 comes with 4000 mAh removable battery. It does a decent job you can expect 4 to 10 hours of continuous backup (moderate to heavy depending on your usage). Battery temp reading was incorrect, always at 25 degrees, but the handset was warm not very hot when using heavy apps.
