Oukitel K4000 is a MediaTek quad core powered smartphone with 4G LTE support. The main highlight however is the build quality, K4000 is made to last. It is using a Magnesium Alloy frame, CNC crafted and the handset also houses a 4000 mAh battery.
Inside the box you will find the K4000 handset, user guide, warranty card, plastic case, 4000 mAh removable battery, data cable, travel charger (5V ~ 1A) and good quality earphone.
K4000 as mentioned is a tough handset, very good build quality and finishing. Weight with battery is 205 grams and dimensions are 70.75 x 143.88 x 10.76 (mm). The sides are silver colour with shiny silver borders.
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.
There is no LED notification and K4000 is packed with 3 sensors – light, proximity and accelerometer.
Oukitel K4000 sports a 5 inch screen with 1280 x 720 pixels resolution. The screen has also been made tough. It is using tempered glass with 3 anti scratch 9H later protection. I did a hammer test with the K4000 – do check the video review.
Colour reproduction, viewing angles and touch response are very good.
