Oukitel has refused to include earphones in the box for some reasons best known to them but that not withstanding, the K4000 pro has a thickness of 12.5 mm and weighs approximately 250 grams.
Hardware And Design
Oukitel might not have the most beautifully designed nor the slimmest smartphones out there but sure have their say in terms of design, the K4000 pro is finely crafted with a 2.5D CND metal chasis around the border with a curved arc design, the arc design which is absent in the former K4000 is said to give the device more protection from drop falls, this literally makes it a drop-proof smartphone.
At the top, you’ll find a micro USB port and a 3.5 mm headphone jack, the power button lays by the left as the volume adjustment keys occupies the right side of the device. Only the micro phone hole can be seen at the bottom.
The back is covered with a crocodile leather, when you decide to take off the cover, you’ll be looking at a big 4,600 mAh battery. There is a space for micro SDcard by the left and the two spaces for your micro and normal SIM cards at the other side.
In the screen department is where the K4000 pro offered the most, it crammed a 5.0 inches screen with a resolution of 720 by 1280 pixels and a PPI of 294 which is just okay for a 5-inch screen. The screen has a full 3D support, the overall performance of the screen is really impressive, it looked like something higher than just 720 pixels although there’s a barely noticeable yellowish tint to its colors. White gets shifted a bit towards yellow when you look at the screen at an angle, but everything remains very clearly legible and the colors are very vibrant. The contrast and brightness are both obviously great.
The thickness of the screen is said to be 1.1 mm which is higher than the normal 0.7 mm found in most touch screen phones, the glass also has a protection of 9H hardness, highly resistant to scratches, pressure, shocks and drops. Three action button with no LED lights are located just below the screen; The back, home and menu button, the proximity sensor is located at the top with the front facing camera, there is no notification light in the the device.

The native storage available on the K4000 Pro is 16 GB and it can be further expanded to up to 64 GB of microSD card if the user requires more storage space.
We ran an AnTuTu Benchmark test on the K4000 pro and below are the results;
The device has 8 Megapixel camera at the back with 13 Megapixel interpolated, this means the 8 MP camera can function as a 13 MP camera, as you can see in the AnTuTu benchmark records above, it shows 13 instead of 8 Megapixels for the camera. There is a single LED flash light just below the camera which will ensure bright pictures even in dark conditions, the camera can capture up to 4160 x 3120 pixel pictures, it also features auto focus, HDR, Geo-tagging, Panorama. The front facing camera has 2 Megapixel with 5 Megapixel interpolated, it can capture up to 2880 x 1728 pixel pictures.

It also supports Wi-Fi and Wi-Fi direct, bluetooth v4, A-GPS and USB OTG support. The smartphone also comes with some pre-installed apps like; the google apps, radio and it also features document viewer and image editor.

From our personal user experience, it took 9 minutes of heavy browsing with full 3G before the battery went down by just 1%.
No doubts, the Oukitel K4000 pro was built with durability in mind, for those that find it difficult maintaining the screen of there touch screen smartphone and need something that can withstand those severe falls, frequent scratches an all those reckless handling, You should be thinking of getting a K4000 pro for your self, not only will get a relatively strong smartphone, you’ll also get a large battery and other cool features at a very affordable price of just 120 USD which is around NGN37,000 (with the current exchange rate) in Nigeria.
