Review (part 1)

Introduction

This is the OUKITEL K7000.

Hardware

This device is powered by a Mediatek MT6737M SOC clocked at 1.25GHz, a new CPU from Mediatek that is basically an MT6735 with a new Modem that supports VoLTE, together with 2GB of RAM and 16GB of ROM. It features a 8MP (interpolated) rear camera and a 5MP (interpolated) front camera.

Unboxing

Packaging comes with many accessories: 1x Micro-USB Cable, 1x 5V/1A USB Charger, 1x Quick Start Guide, 1x Warranty Certificate, the Huge 5000mAh Battery Pack that works as a cover and the Smartphone (of course). A screen protector is already applied.

Talking about the Battery Case, it provides extra 5000mAh of Battery Capacity (real ~5300mAh) and works just like an AC Charger. Depending on the remaining power of the device's battery, you can choose to power on/off the battery case. Even though it doesn't provide the same protection that a TPU Case does, if you drop the device you might break the battery case, but not device itself. (unless you drop it face-down).

In my opinion, it would have been better to have an internal 3000mAh battery and an external 4000mAh Battery Case in order to provide the best compromise. Anyway, this is what OUKITEL choose to produce. Thanks to the Battery Case USB Port, it can be also used as a classic power bank to charge other devices. Let's call it a pseudo power-sharing feature.

Back to the device, it is 14.45x7.14x0.87cm, not extremely compact, with medium bezels. It weights 159g, super-light for a Metal Chassis device.

Its chassis is one of the best i have ever seen. It is completely rounded, solid and well-made. Even the Power/Volume Keys are made of metal. Well Done OUKITEL!

On the front side there is the usual 2.5D Curved Display and the upper front side of the device features a Front-Facing Camera, an Earpiece, and the Sensors hole that includes Light, Proximity and Gesture Sensors.

On the lower front side there is the Touch Keys area, with Menu, Home and Back touch, but hidden, buttons together with the almost invisible Notification LED. (a White Circle that lights up). Its brightness is ultra-low (as you can see) and doesn't support multiple colors.

On the back side there is the removable back cover, with a rubberized surface that improves the grip of the device and makes it a bit premium, even though it is a fingerprint and dust magnet.

The upper rear side of the device features the slightly protruding Camera Sensor supported by a single rounded Flashlight, and the compact, rounded, super-comfortable Fingerprint Scanner.

On the lower rear side there is just the OUKITEL logo because the Speaker is located near the Micro-USB port.

Device

Screen

Screen Quality is average, color reproduction isn't the best. Considering that there is no MiraVision support, this can't be improved. As regards the brightness, it is good for any kind of usage.

The Light Sensor supports super-smooth light changes, providing almost instant brightness changes as soon as the light changes. This is its maximum brightness.

Viewing Angles matches IPS screen capabilities, with no major issues.

Camera

Considering that the Rear Camera is a 5MP (interpolated to 8MP) GalaxyCore GC5005 sensor, photos quality is pretty decent. I have tested another device with the same camera sensor, and the way OUKITEL implemented it is much better.

"HDR off" on the left and "HDR on" on the right.

Macros and Wide photos are pretty sharp, even though i notice a slight yellow tint in the Sky photo.

Flashlight is powerful enough, sufficient to improve low-light photos but do not expect superb light. (do not compare it with Dual-LED configs)

As regards Video Recording, 720p videos are recorded with a decent level of details, frame-rate is average between 15 and 25 fps.

Front Camera records sufficient photos for video-chat and occasional shots and isn't a Wide-Angle variant.

Audio

Speaker Quality follows other OUKITEL devices, no low-frequencies (just like most devices) with no distortion at maximum volume. Its volume isn't super loud, but neither super quiet. A good compromise to get decent audio quality.

As regards the Microphone, it works decently well in any case (in-call, VOIP, etc...), and the earpiece is loud enough to be used in any condition.

GPS

Compared to other MT6737 devices, this is the one that gets the best GPS signal. High Accuracy, even indoors, and no issues while using it.

Indoors on the left, outdoors on the right.

Telephony, Mobile Network & WiFi

This device supports all European 4G/LTE bands, including Band 20, and the signal was stable almost everywhere.

Also 3G Signal Reception is accurate, actually I never managed to get connected to the 2G Network of my Mobile Operator because there was always some 3G Signal available.

4G Network Speed is sufficient, it highly depends on your Mobile Operator and mine isn’t pretty good. While 3G Network Speed is a bit low, just like on every Mediatek Device i have tested.

WiFi 5GHz isn't supported here. With my 2.4GHz network, i was able to reach almost 42mbps, connected at 65mbps, with the same ping that i get on my Desktop PC.

Battery Life

I have measured the real battery capacity using my USB Tester, and it seems that the real battery capacity is much higher than the declared one (declared 2000mAh, real ~2450mAh), impressive!

The External Battery Pack, or Battery Case, is impressive too. Real Capacity higher than declared (~5300mAh), Unfortunately i can't provide you any test about how many users the device lasts with the battery case because there are no battery benchmarks that can be run while plugged to the AC charger, or Battery Case.

This is the Geekbench Battery Test, the battery runtime is sufficient for a 2000mAh battery, the battery case should provide 2.5x this battery runtime.

As regards battery charging times, the 5V/1A charger is enough for a normal charging runtime, but you can't expect super-fast times.

Software

Following the usual trend, OUKITEL choose an almost completely clean Android 6.0 release and it provides a buttery smooth experience (except Animations, known MT6737 bug). No third-party apps are installed.

Just like other last-gen Mediatek Devices, there are some typical features such as Gestures, Scheduled Power On/Off, etc…

Notification LED settings are child friendly, just three options to manage it. Not customizable at all.

As regards the Fingerprint Scanner management, it is pretty easy to configure, and probably one of the most accurate i have ever tested, reaches high-end scanners without any doubt.
