Umidigi Z2

In our recent test, the Umidigi Z2 Pro did not have to face too many complaints. Now we examine the slightly more affordable Umidigi Z2 to evaluate whether the built-in mid-range hardware with Mediatek's Helio P23-MT6763V SoC, the ARM Mali G71-MP2 graphics unit, 6 GB of RAM and 64 GB internal storage also delivers a good performance.

In the price-range of affordable smartphones costing around 250 Euros (~$283; $256 in the US), numerous competitors are also represented, and the Umidigi Z2 has to face devices with a similar price-performance ratio in our test. We select the LG Q Stylus, the Samsung Galaxy A6 Plus (2018), the Honor Play, and the Wiko View 2 Pro for our comparison.

Case - Multiple colors

In the Z2, Umidigi uses a rounded design with color gradations that appear metallic on the back. This "gradient color" effect is available in the variants called "Twilight" and "Phantom," with the first offering a color gradation from violet to green and the latter a darker, black design. The transitions between the various case sections are cleanly done and all of them are rounded, so that there are no edges or corners. This makes the Umidigi smartphone very comfortable to hold in the hand.

With a weight of 165 g, the Z2 is one of the lightest devices in our comparison list, and the dimensions of the 6.2-inch device are also moderate compared to the competitors, which can be traced back to the very small bezel around the display.

Equipment - An affordable Chinese smartphone with good equipment

The Umidigi Z2 offers solid mid-range equipment, bringing a Helio P23-MT6763V SoC from Mediatek, ARM's Mali G71-MP2 graphics unit, 6 GB of RAM, and 64 GB of internal storage. You can expand the storage by up to 256 GB via the internal microSD card reader. However, if you do that, the dual-SIM function will not be available anymore. To charge the device and for wired data transfer, there is also a USB Type-C connection, but this is only connected internally via the 2.0 standard.

Software - Pure Android without third-party apps

The Umidigi Z2 brings Android Oreo version 8.1 with the security updates on the level of May 5, 2018. The manufacturer uses a pure Android system and also refrains from installing its own apps. Therefore users do not have to struggle with preinstalled apps but can freely decide about the apps on their own system. If several users need to access the Android smartphone, you can setup different accounts in the Settings menu.

With the GPS Test app, we evaluate how accurately the Umidigi Z2 is able to determine its own location. It shows that the location can be determined outdoors with an accuracy of up to four meters. However, the Android smartphone is unable to create a satellite connection indoors.

In our mandatory bike tour, we compare the Umidigi Z2 to our Garmin Edge 520 reference device. Particularly during long, straight stretches, the recorded route is good. Depending on the speed, the Android smartphone records the route of tight curves better or worse. In parts, even larger curves are not recorded correctly over a large distance. This makes the GPS in the Umidigi Z2 more suited for simpler, everyday navigation tasks.

Telephone Functions and Voice Quality - Android smartphone with good calling quality

Users of the Umidigi Z2 can make phone calls with Google's standard app, allowing them to quickly and easily enter phone numbers manually. The calls and contact lists are displayed on two additional tabs. During phone calls, the earpiece of the Android smartphone offers a medium volume with the conversation partners being clearly understandable. While the sound spectrum offers fairly emphasized mids, this does not lead to distorted voices or any problems during the conversation.

Cameras - A smartphone for good snapshots

Image taken with front camera
Image taken with front camera

Umidigi has equipped the Z2 with a 16+8 MP main dual camera system with an f/1.7 aperture and a 16+8 MP front camera with an f/2.0 aperture. The latter allows you to take good selfie pictures that shine with clearly delimited colors and objects even in weaker light conditions.

While the main camera of the Umidigi Z2 succeeds in taking good snapshots, shady image areas are reproduced slightly too dark. Also in panorama pictures, the colors are too pale and objects do not appear clearly separated from each other. While the details are still recognizable, they become blurry with increasing distance. In close-up range, the camera of the Android smartphone is able to take detailed pictures with saturated colors. But shady areas also turn out too dark here, causing the details to be lost. On the other hand, bright areas are sharp and well delineated, as long as they are within the focal range. The relatively low aperture allows the Umidigi Z2 to reproduce recognizable objects even in bad light conditions. While our test image is far from being a sharp picture, at least the selected object and its colors can be recognized. The camera app merely offers some color filters, a panorama, and a bokeh mode. Separate settings such as white balance, ISO values, and exposure cannot be adjusted.

The video function allows you to take recordings with a similarly good quality as our test pictures. An image stabilizer prevents too much blurriness. However, there is nothing here like a professional mode allowing the user to influence the quality.

Using the ColorChecker Passport, we evaluate the color reproduction of the Umidigi Z2 camera. It shows that the colors are reproduced slightly too dark. Green color tones are matched most accurately, but gray and also black tones are darker than they should be.

Under controlled light conditions, the Umidigi Z2 is able to reproduce our test chart well. Colors appear saturated, and details and fine structures can be easily recognized. The bottom corners turn out slightly pale.

Accessories and Warranty - Umidigi smartphone with a 3.5-mm adapter

The Umidigi Z2 includes a USB charger plug with the corresponding USB Type-C cable, a SIM tool, a protective cover, and an adapter from USB Type-C to 3.5 mm audio. Umidigi does not offer any specific accessories.

Umidigi offers a 12-month warranty to users. The Z2 is also available from European vendors, but buyers who still want to import it can rely on the vendor warranty requirements (in Germany). 

Input Devices and Operation - Chinese smartphone with a good touchscreen

Umidigi enables input on the Z2 using Google's GBoard keyboard app, allowing you to input text quickly and without any complications. The touchscreen quickly and reliably transfers any touch to the system, responding to every input with a slight vibration. Drag-and-drop movements can be performed on the smooth display surface without any problems. The position sensor also responds quickly and adjusts the display content according to the smartphone position without any delay.

There is a fingerprint sensor on the back of the smartphone. This responds quickly to any stored fingerprints and unlocks the Android smartphone reliably.

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8933 (minimum: 43 - maximum: 142900) Hz was measured.

Our measurements attest the Umidigi Z2 with a good contrast ratio of 1073:1, which places it in the middle of the field of comparison devices. While the black value is slightly elevated at 0.44 cd/m², this also corresponds to the average of the competitors. Furthermore, the manufacturer does not use PWM to control brightness, which should benefit sensitive eyes. The CalMAN analysis shows a clear blue tint. The smartphone does not offer an option to manually adjust the color temperature.

Performance - A mid-range smartphone with good performance

Umidigi has equipped the Z2 with Mediatek's Helio P23-MT6763V SoC and ARM's Mali G71 MP2 graphics unit. In addition, there are 6 GB of RAM and 64 GB of internal eMMC flash storage. With this, the smartphone offers solid mid-range equipment that enables smooth system operation with the pure Android.

In our benchmarks, the smartphone shows a performance in the mid-range of our comparison list. During graphics-intensive tests, the performance turns out slightly lower. However, in everyday operation, the Umidigi Z2 allows you to run all applications smoothly and even offers some small reserves for casual games, for example.

The internal storage of the Umidigi Z2 shines with good read and write rates that are slightly above the average of comparable devices and ensure that the data storage can be accessed without any delay.

The internal storage can be expanded by up to 256 GB via the microSD-card slot. The Android smartphone also achieves good read and write rates here with our Toshiba Exceria M501 reference storage card. However, if you use a storage card, you will lose the dual-SIM function, and apps cannot be moved onto the card.

Games - Demanding games only with longer load times

An ARM Mali G71 MP2 handles the display of the image content in the Umidigi Z2. This graphics unit offers sufficient performance for simple games and applications with low demands on the graphics performance. During more-demanding games, you have to expect longer load times and the graphics quality may need to be adjusted lower. The Asphalt 9: Legends and Arena of Valor games we tested ran without any problems, but higher graphics settings caused some slight stuttering. The operation of the touchscreen did not present any weaknesses, and the position sensor also transferred any movement directly to the game.

During idle operation, the surface temperatures of the Umidigi Z2 always remain at around 25 °C (77 °F). Under load, they increase by slightly more than 10 °C (18 °F). The phone merely feels hand warm but never hot. The demanding GFXBench Manhattan 3.1 test also shows that the temperatures inside do not impede the system performance even after longer loads.

Speaker characteristics

The speaker of the Umidigi Z2 offers mediocre volume. The sound spectrum is dominated by high mids and hardly offers any lower tones. The sound is therefore imbalanced and only suited for the occasional reproduction of media content. You can connect a wired headset or external speakers to the smartphone using the included USB-C-to-3.5-mm adapter, which accepts the corresponding plugs tightly and does not negatively influence the audio quality.

Battery Life - Umidigi smartphone with long battery life

Power Consumption

The Umidigi Z2 is an energy-efficient device. While some of the competing smartphones do slightly better in our measurements, with a minimum of 0.9 watts during idle and a maximum of 5 watts under load, the Chinese smartphone is not a power guzzler.

The included 18-watt charger is sufficiently sized to provide the Umidigi Z2 reliably with power at all times.

In review: Umidigi Z2. Test unit provided by Umidigi
In review: Umidigi Z2. Test unit provided by Umidigi

In our test, the Umidigi Z2 reveals itself as a good mid-range smartphone. The large amount of working memory in combination with a pure Android system ensures smooth system operation, and the lack of preinstalled apps offers users complete freedom to decide which apps to install on their smartphone.

The Umidigi Z2 offers a good all-round package with a suitable price and performance.

For a relatively affordable price, users receive a solid smartphone that keeps its promises. The camera offers sufficient quality for occasional snapshots, and the fingerprint sensor unlocks the smartphone reliably. The design and colors turn it into a real looker, but users can also hide this inside the included protective cover.
