Hi.
Only I have problem with gps? Umi Iron can't connect with satellites but he sees them. I have rom v1.6. what's problem? greetings

\n\nAfter fixing the configuration/software issues,
let's get on the hardware side of the GPS problem:

On this picture below you may see the dismantled upper part of an UMi iRON device:

UMi iRON GPS Antenna

In my case,
the actual antenna contact pins (seen in the left red rectangle) were bent 360 inside so there was no metal-on-metal contact with the GPS module (seen in the right rectangle).
Straighten them, and when assemble back the top plastic cap, watch out for them to stay straigh and properly contat with the GPS module pins.

But that's not all.
If you want a GPS fix time less than 1000 ms on at least 8 satellites even inside a building,
cut out a piece from baking tin-foil, following the contour of original antenna (you'll see the pattern when you inspect the black piece thoroughly),
and set it over the original antenna, as an intermediary antenna.
Beware, and cut out the piece with separeate, at the beginning, two nodes.
Otherwise, it will not be a (good) antenna.

And... results of this mod are smashing. Truly.
Good luck!

Hi,

Install Mobileuncle Tools and run Power GPS Search. Then run the Engineer Mode (MTK), scroll right to the Location tab and run YGPS. See what happens with the satellites.

IRON UMI has problems with accuracy and location time, but can detect satellites even in the building.

Also, make sure that your software version is 1.5 or even 1.6.

so, power gps search didn't help me. but when I insert Umi Iron into this he fix.

can I do anything about it?

What an interesting solution! So this problem seems to be a hardware issue. The GPS antenna probably has a bad connection to the mainboard and that aluminium tray can substitute or boost it somehow. So the solution would be to disassemble the phone and fix the GPS antenna.

I had this problem too after updating to v1.6. I installed from Play Store the "MT GPS EPO fix" by GoCode. Ran, clicked "download epo files", restarted the phone. Since this the phone find, fixing gps quickly. Give it a try ;)

\n\nhow can I fix the antenna?
Unfortunately, this program does not help.
I noticed, too, that the reversal of the phone upside down increases the number of connections
