Foreword: UMIDIGI Z2 Pro
Who deals with China smartphones, that is UMIDIGI probably a term. Above all, the manufacturer is known to "hype" new devices immeasurably in order not to deliver what most buyers expect. From a dual camera in DSLR quality is then fast a fake dual camera and even with the battery capacity, it is not always so accurate. With the UMIDIGI Z2 Pro UMIDIGI has again launched a smartphone on the market, which promises much purely from the data sheet.
Design, workmanship and delivery
The UMIDIGI Z2 Pro is an upgrade of the most recently released UMIDIGI Z2. Both smartphones share the same housing design. Striking is the shimmering back in the light, which, however, is not multi-layered, but merely painted. This is available 153.4 x 74.4 x 8.3 mm large and 165g heavy smartphone in the colours "Twilight" and "Carbon Fiber", In addition, a special edition in a fine ceramic look is available.
The UMIDIGI Z2 Pro is set up as follows:
front side is the 6.2 inch large display with Notch. Apple's iPhone X has made the so-called Notch socially acceptable. Many manufacturers, especially from China, jumped on the bandwagon. The Notch is a recess at the top edge of the display, which in the case of the Z2 Pro surrounds the receiver, the front camera and the sensors. A Notification LED is not present!
The metal one housing frame includes right hand a power button and a volume rocker. Left hand is the Hybrid SIM slotwhich can be equipped with two Nano SIM cards or one Nano SIM + Micro SD. On the underside there is a USB-C socket in the middle, on the left a microphone and on the right the loudspeaker. Another microphone is located inside the frame top. On a classic 3.5 mm jack audio output is omitted.
The back our test specimen shines in the Twilight look, with a turquoise-purple gradient. The back is made of glass, which reduces the susceptibility to scratches. Disadvantages of the reflective back are the high susceptibility to fingerprints and the somewhat slippery feel. In the upper section of the back is the main camera with side LED flash and underlying fingerprint scanner.
The quality of workmanship of the smartphone is not objectionable overall. The case frame and the back are almost seamless despite their composition. The buttons have a good pressure point, but sit with some play in the frame. Of the What's in the box In addition to the smartphone includes a protective cover in leather look, a Pump Express quick charger, a USB-C cable, a USB-C to 3.5 mm audio adapter, a SIM needle and a user manual and a Thanksgiving card.
The display of the UMIDIGI Z2 Pro solves at one Diagonal of 6.2 inches with 2246 x 1080 pixels on. The point density is at sharp 402 PPI. The screen-to-body ratio specifies UMIDIGI with 90%. When calculated, the Notch ratio is close to 80%.
Display measurements showed a maximum luminance the display of about 350 cd / m², The measured black value is 0.214 cd / m². This results in a static Contrast ratio of 1: 1636, The illumination of the display is even and without visible irregularities. From the sRGB color space, however, the smartphone differs significantly. Striking is above all the very cool vote with a slight blue cast.
Display in everyday life
In practical use, the display of the Z2 Pro can be seen. The presentation is razor sharp. Individual pixels are invisible to the naked eye. Colors are displayed strongly despite the cool touch. An individual customization of the color representation is not possible. The maximal display brightness All you need to do is read the display outdoors, especially in the sunshine. Pluses the display collects even in the Viewing angles, Especially flat viewing angles do not lead to any serious impairment of color hue and color contrast.
Display settings and functions
The settings around the display are clear. Although UMIDIGI lists a color customization option (MiraVision), it was not yet integrated into the system at the time of the test. Likewise, the sleep or reading mode listed in the specifications is missing. Only one adaptive brightness adjustment is possible, which, however, does not reliably adapt to the ambient light! Whether UMIDIGI will provide the features in future updates, will have to show!
The touch screen recognizes up to 10 simultaneous inputs (multitouch), Touches and (swipe) gestures are accurately detected and executed without delay. The used display glass proved to be extremely scratch-resistant in the test lasting several weeks. A grease-resistant coating prevents unsightly marks and provides excellent lubricity.
MediaTek Helio P60
Under the hood comes that MediaTek Helio P60 Middle class SoC is used. The SoC, which was introduced at the beginning of 2018 and manufactured using the 12 nm method, offers MediaTek's NeuroPilot AI interface, which handles AI arithmetic tasks. The CPU of the system-on-chip (SoC) consists of a total 8 processor cores together. These are subdivided into 2 cluster, consisting of 4 ARM Cortex-A53 and 4 ARM Cortex-A73 cores, The maximum clock rate is 2 GHz. The GPU carries the name ARM Mali-G72 MP3.
The storage facilities of the UMIDIGI Z2 Pro amounts to one 6GB LPDDR4X Memory and one 128GB eMMC5.1 data store, A memory expansion via MicroSD memory card is possible. Because of the Hybrid slots In case of memory expansion, the dual-SIM function is eliminated!
In the benchmark, the Helio P60 Z2 Pro neatly. With a AnTuTu result of approx. 136.000 points the processor places itself just above a Qualcomm Snapdragon 660. Only in graphical applications, the Mali-G72 MP3 GPU has beaten the Adreno 512 GPU Snapdragon 660. The memory speeds lie with a measured Write speed of about 206 MB / s and Read speed of 213 MB / s as well as RAM speed of 6406 MB / s in good midfield.
Specifically based on the UMIDIGI Z2 Pro, the test has a regularly occurring Thermal Throttling made noticeable. The power falls briefly below 60% of the maximum system performance.
Performance in everyday life
In everyday life, however, this circumstance does not affect the user experience. There the smartphone presents itself with a high performance. Animations are displayed smoothly, apps are loaded quickly and even with multiple, simultaneously opened apps, the smartphone does not noticeably slow down.
Games like PUBG Mobile are fluently playable on high graphics settings. The previously noted thermal throttling does not affect the game flow. After an 30 minute gaming session, the smartphone achieves an agreeable temperature of 40 ° C.
The smartphone comes with Android 8.1 delivered. The user interface comes without custom launcher, is on Stock Android ajar and was only slightly extended in terms of settings. Bloatware is not preinstalled. Various Google Apps, including Google Play Services are already included. System updates will be Over-the-Air (OTA) distributed.
The Smart Assistant The UMIDIGI Z2 Pro includes advanced power management that automatically removes apps from the background process. The orientation of the virtual control buttons can be over the point "Buttons" be adjusted. The function "Flip to mute" allows mute calls, alarms and music. With "Sweep" UMIDIGI has integrated a QR scanner into the system. What the smartphone misses is a gesture control.
Attention: The user interface suffers from a critical error!
As soon as you get one PIN + fingerprint / face recognition for secure unlocking and the smartphone reboots, the previously entered PIN is not recognized! The smartphone can be only by a Hard reset reset to default! According to UMIDIGI the error is known and will be fixed in the next update.
In the specifications UMIDIGI introduces the Z2 Pro with one dual main and front camera (16 + 8 Megapixel) on. The main sensor is on Samsung ISOCELL S5K2P7 with f / 1.7 aperture, The predecessor, however, sat on a Samsung ISOCELL S5K3P8 with f / 2.0 aperture. The front camera in turn, uses one 16 megapixel Sony IMX371 image sensor with f / 2.0 aperture, The manufacturer does not provide information on the secondary sensors used.
It quickly becomes clear why UMIDIGI is concealing the secondary sensors. As so often with cheap China smartphones with dual camera are fake sensors. These are built purely for the ornament, without any real benefit benefits. Striking for this is already the measly size of the second lens. A look into the libraries reveals that in addition to the S5K2P7 and the IMX371 also the S5K3P8 of the predecessor, a 8 megapixel S5K4H7 and a VGA SP0A08 sensor are listed.
Practical test of the main camera
The main camera of the UMIDIGI Z2 Pro has potential that the manufacturer does not fully exploit. The pre-installed camera app contains the most basic features and settings that a camera app should offer. In addition to a photo and video recording mode, there is still a panoramic and bokeh mode. HDR is available in a normal and an automatic mode. The setting options include, among others, a scene mode, a stabilizer and settings on the image properties.
The recording quality of the main camera is mixed. In terms of color, the shots of the main camera are rather cool. The HDR mode, however, helps. Of the dynamic Range is limited as usual. Striking is a decreasing sharpness from the center of the image towards the edges of the image. Of the level of detail is still acceptable under good lighting conditions. Convince the can Autofocusthat focuses precisely.

As soon as the lighting conditions deteriorate, the Image grain and the blur distribution visible to. This fact makes itself felt even in cloudy weather! It becomes all the more difficult to make shake-free shots. Details are lost and the autofocus becomes increasingly sluggish.
A hefty criticism conceded the main camera because of Fake Bokeh mode, Instead of extracting the focused object cleanly, the Bokeh mode of the Z2 Pro merely creates a circular blurring effect over the image. With a slider, the blur range can be increased or decreased.
Instead of the promised 4K will be videos with maximum 1080p resolution at 30 images-per-second recorded. The video recording quality is insufficient. Video recordings are pale in color and show a strong grain even under normal lighting conditions. In low light conditions, the grain size increases again. The refresh rate remains constant. The quality of the recorded sound is good, if a bit dull.
A feature of video mode is the electronic image stabilization, Although this somewhat stabilizes recordings, it does show an unsightly tracing effect and a pulsation of the picture.
Practical test of the front camera
The mixed quality of recording continues with respect to the front camera. In low light conditions, the level of detail and sharpness visibly decrease, as well as the camera responds very slowly. Videos takes the front camera with maximum 1080p resolution. Special beauty filters are not available in the pre-installed camera app.
The UMIDIGI Z2 Pro supports those in Germany, as well World's most popular 2G, 3G and 4G mobile bands. The dual SIM slot supports 4G on both slots simultaneously. The SIM card format is Nano. In the test, the smartphone showed a high reception strength with constant signal quality. Despite a tiny handset, the interlocutor was well understood at all times. The built-in microphones ensure a good voice quality, although the external noise reduction could be slightly better.
Wi-Fi and Bluetooth
The smartphone is with one Dual AC WiFi Module (802.11 a / b / g / n / ac) as well as a Bluetooth 4.2 Module equipped. The connection range in the WLAN is neat in both the 2.4GHz and 5GHz networks. The achieved data throughput is average. The same applies to Bluetooth connections, which provided no reason for criticism in everyday life.
GPS and sensors
Not quite as strong are the sensors of the smartphone. A GPS fix is found quickly. To criticize, however, is the flagging signal strength, Especially when navigating through city canyons, the accuracy of the position determination can vary greatly. The built-in E-Compass works as it should.
The sensory equipment includes an ambient light sensor, a proximity sensor, an acceleration sensor, a gyroscope, and a geomagnetic sensor. Also on board is a NFC module, Card emulation is not possible though listed by UMDIGI in the datasheet.
Fingerprint scanner and face recognition
The Fingerprint scanner Unlocks the smartphone in 9 / 10 cases. However, the unlocking time is above average. The face recognition is not to complain about. It was not possible to outsmart them with a simple picture.
The Mono speaker reaches a pleasant volume. Only in the treble range this sounds a bit too harsh. Due to the missing 3.5 mm jack, headphones can only be connected via USB-C or with adapter. The sound through the adapter is full and trouble-free.
The capacity of the battery is UMIDIGI 3550 mAh at. The average Screen-on-Time is at medium display brightness about 7 hours, For normal use with daily telephony, WhatsApp and web browsing, this must be Smartphone recharged after 1 ½ days at the latest be.
As a quick charge function is MediaTeks Pump Express supported. However, the charging power of 18 Watt specified by UMIDIGI was not reached in the test. This was only 15 watts. After 30 minutes, the battery is charged by 35%. After one hour at 70%. A full battery charge took 110 minutes in the test.
Unlike its predecessor, the UMIDIGI Z2 Pro supports so-called Qi loading. The implementation of the Qi-Laden turned out to be a disaster in the review. On the one hand, the back of the smartphone is so smooth that it hardly lays on the loading area (use protective cover!). The bigger problem is that the point of contact can hardly be found. If this is found, the smartphone plays crazy. As if by magic, apps are opened and input is made. The smartphone was charged only for a few seconds.
