Review (part 1)

Introduction

This is the OUKITEL U11 Plus.

Hardware

Following some previous OUKITEL's flagship, also this one is powered by a Mediatek MT6750T (the low-cost Helio P10 basically), with 4GB of RAM and 64GB of ROM. As regards the camera hardware, it features a Micron AR1335 (13MP) for the Back Camera, and another Micron AR1335s (i guess the 's' means small), still 13MP, for the Front Camera. Probably the only device from OUKITEL with a real 13MP Front Camera.

Unboxing

Packaging comes with basic accessories, the standard kit provided by OUKITEL: 1x Micro-USB Cable, 1x 1.5A USB Charger, 1x Quick Start Guide, 1x Warranty Certificate, 1x TPU Cover and the Smartphone (of course). A screen protector is already applied.

The design of the device is pretty unique in my opinion (excluding the camera positioning), with a Plastic Back Cover featuring a satisfying texture, nice to touch, but really slippery. Consider using the included TPU cover to avoid any possible accidental drop. Thankfully the chassis is made of metal, making the device pretty solid.

It is 15.45x7.93x0.87cm, definitely the most compact 5.7 inches device i have ever reviewed, with a weight of 217g, unfortunately pretty heavy considering that it doesn't have any metal back cover neither an huge battery inside.

On the front side there is the standard (well nowadays almost all devices have it) 2.5D Curved Display and the upper front side of the device features a Front-Facing Camera supported by a Single-LED Flashlight, an Earpiece, and the Sensors hole that includes Light, Proximity and Gesture Sensors. A Notification LED is here (RGB).

This is how the Notification LED looks like.

As regards the lower front side, there isn't anything at all because this device is using on-screen software keys and the Fingerprint Sensor is on the back.

On the back side there is the Plastic Back Cover (non-removable, but i think it isn't hard to remove considering the material), with the texture i mentioned before.

The upper rear side of the device features the Camera Sensor supported by a Single-LED - Single-Tone Flashlight, together with the Fingerprint Scanner in the center.

On the lower rear side, excluding the usual OUKITEL logo with other certifications, there isn't anything at all because the Speaker is positioned on the lower side of the device.

Device

Screen

The screen is probably the best part of this device, with the usual high temperature (cold) that most OUKITEL devices have, but in the same time, there isn't a single negative point about everything else. (white balance, colors reproduction...)

Its light sensor supports smooth light changes with a maximum brightness of ~400lux. Not bad at all.

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

Camera

Just like most latest devices from OUKITEL, this Micron Camera Sensor used for the back camera works pretty good on Mediatek Devices, excluding the high noise level that unfortunately is present also on this device.

Something that i don't accept is the lack of an HDR mode, missing also on the K6000 Plus with a different camera sensor. I know that most OUKITEL devices had issues with this mode in the past, but it would have been better to implement it properly instead of removing the feature completely.

Outdoor Photos look pretty detailed, but slightly darker than usual.

The flashlight seems to produce enough light to support the sensor in low-light conditions, but it doesn't look to be 100% on-sync with the shot. (similar issue noticed on the K6000 Plus)

As regards Video Recording, the quality and frame-rate of 1080p30 videos is OK, as good as you would expect from a 13MP camera sensor.

Probably the most interesting feature of this device is the front camera. Being a smaller version of the Back Camera sensor (same model, same brand), photos look pretty similar, but also with the same small issue (not 100% on-sync flashlight). It is a wide-angle variant.

Audio

Unfortunately something that disappointed me is the Speaker Quality. It doesn't only lack low-frequencies, but, also, the volume is really low. Considering the size of the device, there should be enough space to fit a larger and more powerful speaker. I don't understand this choice.

As regards the Microphone, well it is completely the opposite compared to the speaker. It seems to have a really high sensitivity, recording with maximum clarity and balanced volume.

GPS

GPS Quality is almost excellent, with a really high amount of satellites outdoors, and a decent amount of satellites indoors. The signal isn't 100% stable though, sometimes dropping from 16 satellites to less than half. GPS accuracy is higher than average: 7 meters outdoors, 8 meters indoors. A little software adjustment is required.

Indoors on the left, outdoors on the right.

Telephony, Mobile Network & WiFi

Providing full european bands support (with 4G Band 20), the device was able to keep a stable connection to my 4G Network, with decent speeds (considering other devices tested in the same place) and mid-high signal.

WiFi 5GHz is supported, and thanks to the plastic back cover, there are no issues with signal interferences or shielding. Connected at 121Mbps, i was able to reach almost ~60Mbps. Probably not as high as expected from the Link Speed, but still better than using the 2.4GHz connection.

Battery Life

As my usual reviewing routine, i measured the real battery capacity using an USB Tester, and it seems to be way higher than declared, with an extra capacity of ~300mAh O_o (declared 3700mAh, real ~4010mAh)

Luckily, PCMark run just fine on this device even though it is running Android Nougat. Other Mediatek Devices with Nougat (and also some with Marshmallow) caused the Benchmark to stop by itself after some hours. The result is really good, 10 hours for a 3700mAh battery...outstanding.

As regards battery charging times, unfortunately there is an issue with the OS, capping the maximum Charging Current to 0.6A instead of 1.5A, thus causing the charging procedure to be really slow. More than 4 hours required to charge the device completely.

Software

When a company keeps using a Clean Android OS for their devices, i am always happy. (even though the OUKITEL OS found on the K4000 Plus was impressive for a first release)

Using Android 7.0 Nougat, with latest security patches (at least at the time of the review), the device runs without any performance issue, the UI is smooth, with no crap pre-installed.

Just like most Mediatek Devices, also this one features MiraVision, Gestures (such as tap-to-wake) and so on...

There is no Gyroscope or Magnetometer/Compass...as well as the entire OUKITEL line-up. I have already requested this feature many times to the company, even mentioned in all my reviews, but they keep ignoring the request. They could have included at least the Magnetometer/Compass, it is essential in 2017.

No malwares detected with Malware-Bytes Anti-Malware using latest definitions.

As regards the Fingerprint Scanner management, there isn't any issue to report. It works as good as it should, maybe slighly slower to unlock compared to latest OUKITEL devices, but still fast enough.

From a developer prospective, considering the delay between the recognition of the fingerprint and the power-on procedure of the screen, i guess the delay is caused by a slow response-time of the screen.
