The weaknesses in the WiFi are also confirmed in the Z2.
chinamobilemag.de has stated in the test of Z2:
A little disappointing is unfortunately the wireless internet.
The UmiDigi Z2 supports again only a / b / g / n-WLAN, although the processor in principle also AC-WLAN can.
Certainly no end of the world, but without AC-WLAN are in practice only about the 100Mbit / s throughput in the 5GHz band possible.
The reception power moves in the middle field. On the lower floor, the throughput of around 35Mbps is slightly lower than the average of the tested devices (45Mbps).
When leaving the house, the wireless connection then breaks down pretty quickly.
This confirms the difficulties I also have with my Z Pro.
Also the camera of the Z2 does not get a good rating in this test.
For the cameras we are used to adventurous things from UmiDigi and even if the UmiDigi Z2 could shine so far, with the camera it fails.
To be honest, we have already expected that, which is why the disillusionment is limited.
UmiDigi once again pulls out all the stops and delivers everything from bad camera software to incorrect sensor information and a fake dual camera on both sides:
UmiDigi promises a 16MP Samsung S5K3P3 for the main camera and a 16MP Sony IMX371 for the front camera.
Both cameras should each be supported by an 8MP secondary sensor.
At the information can be something wrong, which quickly becomes clear when one inspects the "libcameracustom.so" file.
Here are the following sensors:
Sony IMX371 (16MP)
Samsung S5K4H7 (8MP)GalaxyCore GC2375 (2MP)SP0A08 (VGA)Of the advertised sensors can be found here so exactly one again: the Sony IMX371.
In the front camera, this is certainly not, because the quality strongly points to a 16MP interpolated 8MP sensor out,
which is even clearer, if one considers the increase in quality when reducing the front camera resolution to 8MP Thus,
the Sony IMX371 is more in the main camera. Based on this assumption, we derived the constellation given above in the table.
If you start photographing with the camera app preinstalled by the manufacturer, you will quickly be disappointed.
The quality of the pictures is rarely good, mostly underground. The colors are not right, the pictures are blurred or washed out,
the dynamics are often not right at the front and back and just as often the pictures look completely washed out.
The bokeh mode is as usual a bad fake, the dual camera on both sides useless.
Fortunately, the poor performance is not due to the UmiDigi Z2 itself, but really only to the camera app from UmiDigi.
If you install Open Camera, the quality of both cameras improves dramatically.
At least during the day can shoot quite good pictures, which certainly will not clear prices,
but at least are good enough to watch them on a TV without having to apologize directly for the quality.
Only with night shots and shooting with flash also Open Camera does not work miracles.
The camera generates a clear picture noise quite quickly.
Useful recordings at night are virtually impossible.
Recordings with lightning succeed only at a short distance, but then quite neat.
Here UMIDIGI promised again too much.
Low-light image enhancement
The second 8MP camera specifically designed for shooting in the dark and is incredibly powerful combination with 16MP main camera
to take clear photos in low-light conditions. Now be confident in the darkness with your UMIDIGI Z2 special edition.
