This Device
Conclusions: This Device (Umidigi Z1 Pro) is a low end device in a beautiful garb.
Let me explain why:
First i have notice a yellow shimmer when the display is rotated slightly. Very Bad!
"ANDROID 7.0 IS NOT THE LATEST ANDROIDE" as propagated on your Homepage!
If we are already on Android.
The software is slow and the connection hangs after a good 24 hours.
Only a reboot can fix this.
There are no messages in standby even though it is set that the APP may run in the background.
My OPO 2 made the better photos than the dual camera of the Z1 Pro.
Speed is not the strength of the device.
It always takes a moment until the device opens the app.
All in all, the device is only good for pointing.
You can not work with it. -> A toy would be apt!
If the software would be better, then one could also live with the display.
SO IT IS NOT TO USE!
FIX YOUR SOFTWARE PROBLEM AND THEN BUILD CELL PHONES!
This will be my last UMIDIGI. Apart from that, you get the handle of the software.
