Review (part 1)

Introduction

This is the UHANS A101s.

Hardware

This device, also known as the A101's little big brother, is powered by a Mediatek MT6580 SOC clocked at 1.30GHz, a bit outdated and slower compared to the MT6737M used in the A101, together with 2GB of RAM and 16GB of ROM. It features a 13MP (interpolated from 8MP) rear camera and a 5MP (interpolated from 1.6MP) front camera.

Unboxing

Packaging comes with many accessories: 1x Micro-USB Cable, 1x 5V/1A USB Charger, 1x Quick Start Guide, 1x TPU Cover, 1x Glass Screen Protector and the Smartphone (of course).

Talking about the dimensions, it is 14.34x7.14x0.95cm, almost identical to the A101, with medium bezels. It weights 159g, similar to other plastic devices.

Even though the chassis is similar to the A101, the frame is completely different. This time it is a bit thicker with a Silver Color, making it glossy and a bit less resistant to scratches.

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. No Notification LED is here just like on the A101.

On the lower front side there is the Touch Keys area, with Menu, Home and Back buttons.

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.

The upper rear side of the device features the slightly protruding Camera Sensor supported by a single Flashlight, together with the UHANS logo.

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

Device

Screen

Screen Quality is better compared to the A101, at least on my unit. Color reproduction is decent, its brightness is noticeable higher and the white balance is better.

The Light Sensor supports almost-smooth light changes, with a proper auto-brightness management. This is its maximum brightness.

Viewing Angles matches IPS screen capabilities, with no major issues. Still better compared to the A101.

Camera

Something that has been improved compared to the U101 is the Rear Camera quality. Instead of a Panasonic 5MP Rear Camera sensor (that was already pretty good though), UHANS choose to use a Sony IMX219 (8MP), that seems to provide more details even though photos look a bit more noisy. This is probably related to the Camera Driver.

Macros and Wide photos are as good as you would expect from an 8MP camera, decent quality.

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, 1080p videos are much better compared to the A101, smooth (30fps) and with no stuttering.

Front Camera records sufficient photos for video-chat and occasional shots. Also, it seems to be a Wide-Angle variant.

Audio

Speaker Quality doesn't follow the A101, even though it is louder, much louder, it is highly distorted at maximum volume. No Low Frequencies are here (as always), but excluding this distortion issue, with medium-high volume it is decent.

As regards the Microphone, it works decently well in any case (in-call, VOIP, etc...), and the earpiece is loud enough (maybe a bit too much) to be used in any condition. It doesn't seem to have the same interference issue that i (and other users) have noticed on the A101.

GPS

Compared to the A101, the GPS Antenna is pretty bad. It isn't able to lock, neither detect, any satellite indoors, and outdoors it is just enough for an almost smooth navigation.

Telephony, Mobile Network & WiFi

This device supports, unlike the A101, doesn't support 4G networks, so you have to use your old 3G HSPA+ (42MBps max) connection to use your Mobile Data plan.

Signal Reception is accurate, but 3G coverage is just perfect here where i live so that's something i would have expected. Just like what happens with other devices, 3G Network Speed is low, thanks to my crappy Mobile Network that has lower than average 3G performance.

WiFi 5GHz isn't supported here. With my 2.4GHz network, i was able to reach almost 46mbps, connected at 65mbps, with the same ping that i get on my Desktop PC.

Battery Life

As always, i have measured the real battery capacity using my USB Tester, and it seems that the real battery capacity is lower compared to the declared value (declared 2450mAh, real ~2200mAh), this is something common on all UHANS devices though.

This is the Geekbench Battery Test, the battery runtime is impressive for a 2450mAh battery, much better compared to the A101. This clearly means that the battery has been properly configured here.

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

Just like previous UHANS devices, also this one is using FreemeOS 6.0 (based on Android 6.0) that provides some extra features to the OS without customizing lots of stuff. Basically you can get rid of almost all FreemeOS apps by using an alternative launcher.

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

Even though the OS has been customized, it feels as smooth as others that haven't been customized, and most important, it is smoother compared to the A101.​
