UMIDIGI Z Pro Review | Unboxing & Hands-On

What's in the box

The UMIDIGI Z Pro is just like the model without Pro addition in one practical metal box delivered. Also with the delivery there are no differences. Included are next to the smartphone still one Pump Express charger, a cool one USB Type-C cable, a multilingual Manual and SIM needle.

Design and workmanship

As with the scope of delivery, UMIDIGI also remains true to the design. The UMIDIGI Z Pro impresses with its sleek design Unibody metal case in a cool anthracite look. Because of the unibody case, the back is not removable, which is why the battery can not be easily replaced. On the left side of the case is the SIM slot. Here you can insert either two Nano SIM cards or a Nano SIM card with an additional Micro SD memory card. Who inevitably needs the memory extension, must because of the Hybrid slots do without the dual SIM function of the smartphone!

Another design feature is the capacitive and front side home button, which at the same time the Fingerprint scanner includes. Two additional capacitive buttons are located to the left and right of the Home button. Unfortunately, these control buttons are not lit. On the right side of the case are the physical volume rocker and the power button. There are no other design elements that would make the UMIDIGI Z Pro different from other smartphones.

Unfortunately, UMi or UMIDIGI was never for one high quality workmanship known. The UMIDIGI Z Pro, on the other hand, shines with its solid build quality. The entire housing is clean and processed without gaps or deviations. The control buttons are tight and do not rust even during fast movements.


The smartphone uses a Full HD Sharp IGZO display with a diagonal of 5.5 inches. The higher electron mobility of the "Indium-Gallium-Zinc-Oxide" (IGZO) displays, among other things, results in higher reaction rates, which largely avoids a "drag-on effect". The NTSC color space covers the display with up to 95%. UMIDIGI uses the so-called screen protector "Dragontrail glass".

In practice, the display of the UMIDIGI Z Pro performs well, but is not perfect. The color representation is comparatively cool. Within the display settings there is the possibility via "Miravision" or the option "Color Temperature" to customize the color representation individually. What also stands out is a low "backlight bleedling" at the top and bottom of the display. If, for example, very dark contents are displayed, an uneven brightness progression becomes noticeable. Convince the UMIDIGI Z Pro in the viewing angle stability and the display sharpness. Even at extreme viewing angles, colors are rendered unadulterated and fonts remain legible.

The maximal display brightness is average. Being able to read content in bright sunshine will be difficult, as the display is extremely reflective and prone to fingerprints. The accuracy of the touch screen is good. Ghosting or erroneous detections did not exist in the test. Multitouch is supported with a maximum of 5 concurrent inputs.


Auch der MediaTek Helio X27 (MT6797X) processor is back on board. The processor has a total of 10 processor cores, which are divided into 2 Cortex-A72 and 4x2 Cortex-A53 cores. By dividing it into 3 clusters, work tasks are efficiently distributed to the respective clusters depending on the computing intensity to guarantee better performance. At the same time (at least in theory) the battery consumption should be reduced. Regarding the storage equipment, the smartphone is with a 4GB large memory and a 32GB large internal memory equipped.

Although the UMIDIGI Z Pro uses a high-end MediaTek processor, the performance is only partially satisfactory. Especially in multitasking have become Delays and app crashes notably attributable to the processor itself, but to its adaptation to the user interface. In some cases, apps did not even want to start at all or stuck with a white screen. There is still a need for optimization on the part of UMIDIGIs.

As processor graphics is a Mali T880 MP4 GPU used, which has grown even more demanding games. If you like to play mobile games like Dead Trigger 2 or Asphalt 8, you can play them smoothly on high details. But beware! The smartphone gets hot after a short while.

User Interface

Used is a clean, based on Stock-Android Android 6.0that completely without bloatware gets along. Only in the settings additional functions were added. So there are, among others expanding display settings or one "Intelligent assistant", which includes power saving features, notification LED settings and key control. The standard activated, virtual control buttons can be completely switched off so that the display can be used extensively.

Updates receives the smartphone over-the-air. On Update on Android 7 presents UMIDIGI. However, when it will be so far, is not yet known.


The most important difference between the UMIDIGI Z and the Pro version is the main camera. The single camera system (Samsung S5K3L8) of the UMi Z, was the UMIDIGI Z Pro by a Dual camera system consisting of two 13 megapixel Sony IMX258 image sensors replaced. The laser autofocus is dispensed with. Instead, you have to deal with a conventional one PDAF (Phase Detection Autofocus) to be satisfied. The 13 megapixels front camera you can Samsung S5K3L8 image sensor remains.

main camera

In practice, the recording quality of the main camera can be assigned to the middle class. In good lighting conditions, you can take beautiful pictures with good sharpness, strong colors and low image noise. In poor lighting or low light conditions recordings are increasingly blurred and the image noise increases significantly. Autofocus works accurately and reliably. Of the "Quad LED Flash" provides a passable illumination in the dark, but is no brighter than a conventional dual-LED flash.

Particularly interesting is the so-called "Bokeh" effectwhich is enabled by the dual camera system. "Bokeh" means nothing but "blurry". As a result, objects or people are better placed in the foreground, whereas the background is blurred. This effect is created on the software side by a virtual apertureDerived from F11 to F0.8 enough. Already shot bokeh shots can also be edited later in the gallery by moving the virtual aperture and refocusing. The bokeh recording mode is unfortunately not implemented very well with this smartphone. Compared to the recently tested by us Honor 6X, which also has a bokeh mode, the adjustment of the virtual aperture in the UMIDIGI Z Pro is comparatively difficult. To put the person or the object in the foreground perfectly requires a lot of tact and patience. In addition to bokeh photos are also Bokeh video recording possible.

Other photo modes are monochrome black and white recording mode, there is one "Facebeauty" modewho did not want to work in the test, there is one "Pro Photo" mode with individual customization options and one Panorama mode, If you want to spice up your pictures, there is something for you different filtersthat can be placed directly over the live image. Videos takes the main camera of the UMIDIGI Z Pro with maximum 4K resolution. Unfortunately, the refresh rate can not be adjusted individually.

Shooting mode: Standard

Shooting mode: Bokeh

front camera

The front camera surprises with a decent recording quality. Those who like to take selfies, get their money. It is also surprising that front-side LED flash, which ensures sufficient illumination at night. As additional recording modes, the front camera also offers a facebeauty mode and a panorama mode. Videos can even be recorded in full HD.

Connectivity, GPS and sensors

In the mobile network, the UMIDIGI Z Pro supports all the usual frequencies in this country. Even LTE is fully usable. The connection stability in the mobile network is good. Mobile surfing works without any problems. The Call quality is mediocre, which is mainly due to the weak microphone. Even with the Freichsprechfunktion the smartphone delivers no great performance. The speaker sounds slightly tinny and lacks volume.

Im Wifi The smartphone behaves perfectly and retains a constant signal even at further distances to the transmitting unit. Dual-band WiFi is supported and switching between 2.4G and 5G works fine. Bluetooth will happen until version 4.1 supported. Again, there is nothing to complain about.

A GPS Compass Fix finds the smartphone within a few seconds. Even inside the building, a GPS fix is ​​possible after a good 10 to 20 seconds. To the signal strength of a Xiaomi Mi5S However, the UMIDIGI Z Pro does not come up. Nevertheless, precise navigation is no problem. Positioning was consistently accurate across a variety of test navigation through urban areas and over land. On E-Compass is also available so that the smartphone can also be used for pedestrian navigation.

The sensory equipment includes a proximity sensor, an accelerometer, a brightness sensor, a gyroscope, a Hall sensor and a G-sensor. On fingerprint sensor is also available. This is characterized by a good recognition rate, but is a bit sluggish when unlocking the smartphone.


To criticize is the battery life. Despite a capacity of 3.780 mAh Do you come with a battery just just so over the day. In power hungry applications, but also in standby, the battery consumption is noticeably high. The load time is an average of 2 hours and 30 minutes. From the promised Pump Express no trace.

GPS & sensors

Great design, good workmanship, but greatly improved by the software. Especially the occasional app crashes and the often sluggish usability of the user interface led to much frustration in the test. But there is hope, because the release of future updates and an upgrade to Android 7, it is not so bad. Fortunately, the UMIDIGI Z Pro has no major hardware defects. Although the microphone and speaker quality are rather average, the smartphone shines with the stability of the connection in the mobile network.

The dual camera system also wins no price, but allows at least in good lighting conditions passable video and video recordings. The bokeh recording mode is a nice addition, but it requires a lot of tact. Again to criticize is the battery life. Despite the high capacity, the smartphone is barely accessible during the day. In addition, the promised Pump Express fast charge does not work. But again, there is hope that future updates will eliminate these errors.
