Please install GPS test from play store. Then take phone outside, activate location and switch on  ...

Hello, this is after 20 minutes...

Was your GPS working before last update?
If yes, please update your phone to latest available firmware from this list
http://community.umidigi.com/forum-176-1.html
Also please test GPS with location activated in "device only " and "high accuracy" mode and see what happens.
If still you not receiving GPS signal you definitely have hardware fault as GPS antenna not connected or other issue.

Hello,
I don't know, the phone updated to this release when I powered it on for the first time, I didn't try GPS before.

I checked forum for V1.1_20171126 ROM, but there are some issues reported as well, like problems with camera and LTE/Bluetooth, so I'm not sure, if it will be better with this release... :-(

Is any new release planned in near future? And will be update supported also by FOTA method, or only SPFT?

   Thank you

The hardware fault is a design flaw on the part of Umi, software can't fix a failure in hardware design like there is with GPS on the crystal.

UMI can't make those GPS satellites broadcast a more powerful signal can they?

I have reviewed a bunch of phones, none have had GPS performance as bad as the crystal. Even a $35 dollar super cheap china phone had working GPS.

Not to mention the fake compass and gyroscope, providing nonsense data and confusing some navigation apps making them unusable. It would be better if UMI disabled these fake sensors in the next OTA.

As I mentioned before you probably have hardware issue. You need contact to seller or open phone and check GPS antenna contacts but this will void warranty.
Unfortunately I didn't hear anything about next update.
Which firmware are you using (build number)?

Unfortunately I can't confirm your state about fake sensors.

You have either utterly failed to properly implement a real hardware gyroscope and compass, or they are fake software ones.

Probing with an app reveals an "MTK" gryscope and compass, so they are most likely fake software ones. Calibration does not work, and the data they provide is nonsensical. Everyone who has tested a crystal's "compass" gets the same result, just random data and a spinning compass, even laying flat on a desk. The same is true for the "gyroscope", everyone who has tried gets the same result too, utterly bizarre movement that is completely useless for anything like VR or creating a photo sphere.

The fake compass messes up navigation apps since the map will keep rotating every which way as it thinks the phone is spinning. The fake gyroscope messes up 360 videos or VR as they think the phone is rapidly moving in all kinds of directions when it isn't.

See on your own forum here or on 4PDA, everyone who has tried testing these two sensors gets the same result. The conclusion is that the sensors are fake. Or if not, they're implemented so poorly that they may as well be. You should disable the compass/gyroscope.
