This topic is originally for the Umi Z Pro, but because of the similarity of the hardware
I´m fowarding this topic from UMI Z Pro forum to this forum:
http://community.umidigi.com/thread-15158-1-1.html

Problems discussed so far:

->Dual-sim problem related to the flash;
->Touch Screen problem on scrooling nav. bar;
->High battery drain;
->Dust in front camera;

-> Misaligned focus and camera noise;
-> Battery swollen;
-> Excessive heat;

->Fix for most system errors and advised procedure to do before and an hour after full flash of an ROM;
->Cell data don´t resume working after disconnected from a wifi;
->Permissions problems;


I'll try to add new fixes as I got problems (hope not) or read them in XDA or here...
Best regards,
Lincoln.

New issue and workaround!
Issues:
->Zpro goes agressively to 3G
Workaround:
->Setting the 4g only mode on the DATA SIM:

There's a way to force the 4g mode if you wish:

I'm not responsible for any bricks, fire, global war, etc...

Dial *#*#3646633#*#* , go network selecting  > select the sim with 4g (data sim) > select LTE only.

But you may need to change it back if got no 4g signal as it won go back to 3g alone anymore...
There's an observation: Only one SIM (DATA) can be at 4g at a time (As far as I could test).
Best regards,
Lincoln.

When you force the LTE only mode, you can't send text messages

As far as I know it's possible if your carrier support SMS over sgs.
If you wish to test check if it's enabled at:
Again I'm not responsible for any damage...

*#*#3646633#*#* -> misc feature config-> SMS over Sgs support
