[Device Reviews and Information] Alberto96:
Introduction

This is the OUKITEL U13.

Hardware

This device is still powered by the pretty old, but rocking stable, Mediatek MT6753 SOC clocked at 1.3GHz, maybe an MT6753T or MT6750 would have been better to handle a Full HD screen. It features 3GB of RAM, 64GB of ROM (unlike other OUKITEL devices) and a 13MP Rear Camera, unfortunately interpolated to 16MP.

Unboxing

Packaging comes with basic accessories, just like all OUKITEL devices: 1x Micro-USB Cable, 1x 5V/1A USB Charger, 1x Quick Start Guide, 1x Warranty Certificate, 1x SIM Card Tray Eject Tool, 1x TPU Cover and the Smartphone (of course). A screen protector is already applied.

Being one of the latest devices from OUKITEL featuring an Unibody Metal Chassis, it feels solid, lighter compared to predecessors and with a pretty nice design. Something that i do not like is the position of Volume/Power Keys, on the left (just like the U20 Plus). I do not understand this choice sincerely.

It is 14.93x7.58x0.87cm, pretty common size, nothing to complain about it. It weights 168g, considering the Unibody Metal Chassis this is just fine.

On the front side there is the common 2.5D Curved Display and the upper front side of the device features the standard set of things: a Front-Facing Camera, an Earpiece, and the Sensors hole that includes Light, Proximity and Gesture Sensors. Is the Notification LED here? Yes, it is. (RGB)

Luckily the notification LED is pretty bright, and also barely customizable. Check the software paragraph to know more.

The lower front side is completely empty, on-screen touch keys are used here.

On the back side there is the Unibody Metal Chassis.

The upper rear side of the device features the Camera Sensor supported by a Dual-LED Flashlight (not Dual-Tone), and the not-so-compact, but rounded, Fingerprint Scanner.

On the lower rear side there is just the OUKITEL logo, the Speaker is positioned on the lower side of the device.

Device

Screen

Compared to other devices, the screen is probably the best one i have ever tried on a OUKITEL device, with great color accuracy, decent white balance and enough brightness.

Light Sensor supports smooth light changes, this is its maximum brightness.

Viewing Angles are as good as you would expect from an IPS screen.

Camera

This is the second device (U15 Pro had it too) i try with an OnSemi AR1337 13MP Sensor, that should feature PDAF and great image quality. Well, compared to the previous device featuring the same sensor, this one has much better photo quality, but there is also something worse. Macro Photos can't be taken at all, this is probably a wrong auto-focus calibration that might be fixed with an OTA Update.

"HDR off" on the left and "HDR on" on the right. HDR photos are just brighter, no real HDR. (just like on almost all MTK devices)

Photos taken on medium light conditions are decent.

Macro Photos, as already said, are not so great.

As regards the Flashlight, it is sufficiently powerful to take some nice shots indoors, but not enough for outdoor shots.

As regards Video Recording, 1080p videos are decent, with mediocre framerate. (some frame drops here and there)

Front Camera is a Superb Wide-Angle variant OmniVision OV8859 (8MP), that manages to take some great shots.

Audio

Speaker's Quality on this device is average, not too bad but neither superb, a small amount of low frequencies is here though.

As regards the Microphone, this is what seem to have some issues, at least on my device. There is a slight buzzing noise in the background, pretty noticeable while recording at low dBs. In-call Quality is good, still featuring this noise but the earpiece is as good as on all OUKITEL devices.

GPS

Just like all MT6753 devices, the GPS is good with almost instant satellites lock and decent signal.

Indoors on the left, outdoors on the right.

Telephony, Mobile Network & WiFi

NOTE: If you see "WIND" (Operator Name) on some screenshots, that's my secondary SIM with no Mobile Data, Signal and Speed Tests are made using my Primary SIM Card. This is used only for minor tests.

OUKITEL provides full european bands support, with 4G Band 20 (some other Chinese Smartphones don’t have it).

3G Signal Reception is accurate too, actually I never managed to get connected to the 2G Network of my Mobile Operator because there was always some 3G Signal available. (luckily there are no coverage issues here)

4G Network Speed is average, even though it highly depends on your Mobile Operator and mine isn’t pretty good.

Somehow WiFi 5GHz is not supported here. Connected at 65MBps to my 2.4GHz network, i managed to obtain a maximum of 33mbps, with medium-high signal.

Battery Life

I have measured the real battery capacity using my USB Tester, and it seems that the real battery capacity is lower compared to what OUKITEL declares. (declared 3000mAh, real ~2830mAh). This is the first OUKITEL device with this "issue", so it might be just my review unit.

This is the PCMark Battery Test. Minimum Brightness, WiFi On, SIM Card Inserted and Active. As expected, its lower battery capacity reduces the battery runtime. Unfortunately i managed to lose the result but here you can see the battery stats. 3 hours and 41 minutes, lower than average.

As regards battery charging times, the 5V/1A charger isn't pretty good to handle 3000mAh batteries so expect more than 2 hours of Charging Time.

Software

As always, all OUKITEL devices feature an almost completely clean Android 6.0 release providing a buttery smooth experience in almost all menus and apps, similar to Nexus/Pixel devices, even though there is some Mediatek stuff here.

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

Unfortunately, just like on ALL OUKITEL devices, there is no Compass/Magnetometer neither Gyroscope sensors. I have already gave to OUKITEL the advice to add at least the Compass Sensor on future devices, let's hope that they will hear it.

Mediatek's Notification LED implementation doesn't allow to change any pre-defined color, but at least you can disable/enable the LED for some activities.

The Fingerprint Scanner can be initialized as easy as on all Android 6.0 devices, and its accuracy is great, with pretty fast unlock times.
