[Oukitel (All phone models)] Alberto96:
Introduction

This is the OUKITEL U15 Pro.

Hardware

Powered by a Mediatek MT6753 SOC clocked at 1.3GHz, the device might result a bit outdated, but trust me, this is the fastest MT6753 device ever made. You will know why soon. It features 3GB of RAM, 32GB of ROM and a 13MP Rear Camera, unfortunately interpolated to 16MP. Each built-in hardware is quality-made, made by Samsung, SHARP and SCUD.

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.

This is one of the first Q4 2016 device from OUKITEL made with an Unibody Metal Chassis, and just like all Metal Devices from OUKITEL, it feels super-solid and doesn't have any minor issue. Impressive. Antenna areas, located on the lower & upper parts of the device, are made of Plastic (otherwise the signal would be messed up).

It is 15.30x7.81x0.88cm, slightly larger than other 5.5 inches devices because its bezels are not so small. It weights 204g, 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)

I won't talk about the Notification LED in the Software paragraph because it isn't customizable at all. Here you can see some real-life photos.

On the lower front side there is the Touch Keys area, with Menu, Home and Back touch buttons. Not Backlit.

On the back side there is the Unibody Metal Chassis, nothing to complain about it. Impressive build quality.

The upper rear side of the device features the Camera Sensor supported by a Dual-LED Flashlight (not Dual-Tone), and the compact, 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 a bit warmer than usual (just like all SHARP ones, interesting) and there is no MiraVision menu so you can't calibrate it. Color Accuracy is normal, with natural colors.

Light Sensor supports smooth light changes, this is its maximum brightness. One of the brightest 5.5" screens i have ever tried.

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

Camera

This is the first device i try with an OnSemi AR1337 13MP Sensor, that should feature PDAF and great image quality. Well...i can't say that image quality is great here. It is just average, with great photos only in ultra-high light conditions. I'm pretty sure that this is a software bug, so i hope to see a software update with many improvements. I have already installed the latest OTA update with the "Improve Camera Quality" words in the Changelog, but...it was useless.

"HDR off" on the left and "HDR on" on the right. HDR photos are just brighter, no real HDR.

Photos taken on medium light conditions are pretty noisy.

Macro Photos seems to be great, but as you can see the focus is a bit messed up.

As regards the Flashlight, it is pretty powerful, making my cat looking amazing. (just sleeping, as every cat do...)

As regards Video Recording, 1080p videos are average, a bit noisy though. Again, the software doesn't help here.

Front Camera is a Wide-Angle variant GalaxyCore GC2365, noisy (damn...) and provides a decent level of details enough for nowadays usage.

Audio

Speaker's Quality on this device, unlike previous OUKITEL devices, is much better, a good amount of low-frequencies are here (finally) and the Volume is medium-high. Well Done OUKITEL!

As regards the Microphone, it is super sensitive with no issues as regards its quality. Everyone was able to hear me correctly while in-call.

GPS

Considering that this is a Unibody Metal device, you (and me too) might expect lower GPS quality or accuracy. Well, i do not know how, but OUKITEL managed to find a solution to this drama. GPS Signal is high, even higher indoors (weird), and manages to lock satellites in less than 2 seconds.

Indoors on the left, outdoors on the right.

It seems that other chinese companies should hire OUKITEL engineers in order to get this result on other Full-Metal devices hehe.

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). Unfortunately, even though the 4G signal is high and stable, somehow all speedtests done weren't able to get some nice results. Software Optimization is required.

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)

As already said, 4G Network Speed is low, even though it highly depends on your Mobile Operator and mine isn’t pretty good, this doesn't mean that it is normal to get 3G Speed on 4G network. This is what happens on this device. 3G Network Speed is even lower.

WiFi 5GHz is supported here, and seems to work pretty well with my 802.11n Dual-Band Connection. It isn't able to get full speed (100/20), but it is still a bit higher than 2.4GHz speed. Connected to 54MBps, because it seems that the 5GHz antenna isn't pretty powerful.

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 3000mAh, real ~3200mAh). All OUKITEL devices had (and still have) this nice extra-power.

This is the Geekbench Battery Test, the battery runtime is probably a bit low for a 3000mAh battery, but the Battery Score is higher than average so, it may be improved with future OTA updates.

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 features 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.

As already said before, even though there is a Notification LED, it isn't customizable at all.

The Fingerprint Scanner can be initialized as easy as on all Android 6.0 devices, and its accuracy is decent, not as perfect as was on the K7000, i might say 7/10. It is lightning fast though.
