[Device Reviews and Information] Alberto96:
Review (Part 1)

Introduction

UPDATE 20170125: I got the final retail unit (engineering sample before) so some parts of the review have been updated.

This is the UHANS U300.

Hardware

Powered by a Mediatek MT6750T SOC clocked at 1.5GHz, this is the fastest device ever released by UHANS, and it might be the best one ever released. You will know why soon. It features 4GB of RAM, 32GB of ROM and a 13MP Rear Camera, unfortunately interpolated to 16MP. Also, it is rated IP65.

Unboxing

Packaging here is weird. An huge package, that might look premium, but in reality it is almost empty. Basic accessories are included: 1x Micro-USB Cable, 1x 5V/2A USB Charger, 1x SIM Card Tray Eject Tool, 1x User Manual and the Smartphone (of course). A plastic screen protector is already applied, no glass screen protector included unlike previous UHANS devices.

Here you can see how big, and empty, the package is.

Talking about the Chassis, it is great. I like the design, as UHANS says this is Mercedes-Benz inspired device, and the build quality is higher than average. No imperfections noticed, unlike what happened with the engineering sample, and the device feels rocking solid.

In order to be IP65-compliant, every single port should be insulated, and here you can see the waterproof covers.

It is 15.40x7.99x1.17cm, one of the biggest 5.5" device you can find. It weights 228g, impressive considering the metal frame (be careful though, everything else is made of plastic) and 4750mAh of battery.

On the front side there is a Standard Flat Display (not 2.5D) and the upper front side of the device features the standard set of things with some extras: a Front-Facing Camera supported by a Single Flash LED, an Earpiece, and the Sensors hole that includes Light, Proximity and Gesture Sensors. Is the Notification LED here? Yes, it is, but supports only one color: green.

I won't talk about the Notification LED in the Software paragraph because it isn't customizable at all. Here you can see how it looks like.

On the lower front side there isn't anything at all, on-screen software keys are used.

On the back side there is the Leather Back Cover (not-removable), claimed to be "Real Italian Leather". I have tested the leather using a pretty simple method, a water-test. "Drop a small amount of water on the good, as real leather absorbs moisture.". Result? Nothing happens, so i can't confirm that this is real leather.

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 with a nice opaque black color.

On the lower rear side there is the UHANS logo together with the Speaker hole.

Device

Screen

Thankfully UHANS choose to use a good screen on this device, with nice colors, high brightness and good white balance. Nothing to complain about it.

Light Sensor does not support smooth light changes, struggling to get an accurate value indoors. This is its maximum brightness. Outdoors it provides a nice viewing experience.

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

Together with the good screen, there is also a good multitouch panel. 10-points supported here.

Camera

Even though UHANS choose to use a nice Panasonic MN34152 rear camera sensor (one of my favorites for Mediatek Devices), it doesn't work so great here. The Auto-Focus motor is noisy (a lot). Image Quality is decent though.

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

Macro Photos seems to be great, when you manage to get a proper focus on the object.

As regards the Flashlight, it is buggy (software not fully optimized yet), not synced with the shot and messes up the photos color accuracy, but surprisingly bright.

As regards Video Recording, 1080p videos are recorded at 30FPS, but as you may notice there is an issue with color accuracy. If you want to see the real colors, check my OUKITEL U20 Plus Camcorder Test, recorded in the same time together with the U300.

Front Camera is a Wide-Angle variant OmniVision OV5648. Again, color accuracy seems to be messed up. Even with the Flashlight (on the right), everything looks weird, with a noticeable pink spot on the left side of the photo. It makes my cat looking so bad.

Audio

Speaker's Quality on this device, unlike previous UHANS devices, is great, a good amount of low-frequencies is here (finally) and the Volume is high.

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

Earpiece quality is decent, slightly muffled, but i may know what causes this issue (or better, disadvantage), they are probably using a water filter on the earpiece for the IP65 certification.

GPS

The GPS Antenna is sufficient. Considering the Cloudy Sky during this test, i can't complain about the result.

Weather Photo

Indoors on the left, outdoors on the right.

There is a small issue though, unlike the engineering sample, on the retail unit the signal is not 100% stable.

Battery Life

I have measured the real battery capacity using my USB Tester, and it seems that the real battery capacity just slightly lower than the declared one. (declared 4750mAh, real ~4650mAh).

This is the Geekbench Battery Test, i don't think it is necessary to say something about this test. It talks by itself. WiFi ON (connected), Mobile Data ON (disconnected), Medium Mobile Signal and Minimum Brightness.

As regards battery charging times, the 5V/2A charger isn't super-fast to charge this huge battery, but it is still better than just 1A. There is no Mediatek Pump Express support.

Software

Unlike previous UHANS devices, this time they choose to use 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 there is no Compass/Magnetometer neither Gyroscope sensors.

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 great with almost lightning fast unlock speed.

Just like on the OUKITEL U20 Plus (pretty similar software, interesting coincidence), there are many customizable fingerprint features.
