I have a Tom Tom operating side by side with UMI Super that has 18 ft accuracy reported by GPS Test App and found the UMI perform the Sat Nav just the same using Sygic App.

I am using also a Vernee Apollo Lite that has a 17 ft accuracy and more stable gps capture all the time than UMI for Sat Nav.

A drop in the recent gps complaints may suggest the gps problem may be more of a production issue at the phone release rather than a design flaw as many have insisted.

Any phone with a Snapdragon 810/820 with same spec as UMI Super would cost at least 50% more and has been reported in the Internet for having a better gps handling than the MTK CPU.  However I doubt if any consumer grade cell phone can reliably deliver a 3ft accuracy with the gps triangulations which I understand employed in military equipment at a considerable cost.

I do rely on using mobile phone's Sat Nav a lot but always carry a Tom Tom as an assurance.  Tom Tom is limited by the amount of maps I purchase but Sat Nav App has maps world wide which I could use in connection of my overseas work.

Hey and greetings from Finland. And we have a new GPS un-satisfied customer here. Thats a pity, bacause the phone it self is quite good. Is there any solotion coming to this problem or do I have to send my UMI back to seller ?

Did you not see my GPS accuracy photo?  That was using the Mtk chipset on a Leeco LeTV pro.  3ft.

Suika,

What is the result of your do-it-yourself modification to UMI Super for playing Pokemon GO?

The Item (4) on aluminium foil antenna may be difficult to follow as UMI Super does not have a removable back as showed in your link.

I think my compass is uncalibrated and it is interfering with GPS . Does anyone know how I can adjust my compass ?

So these GPS issues, are they affecting all Super models? or is it a specific batch of hardware that is affected? Surely if UMI have received complaints that GPS was not working, they'd either halt production or modify the current hardware for new batches?

Haha,  in an ideal world.  I suppose we could start a poll based on GPS issues on UMI super with date?  Mine was a pre order first batch,  has GPS issues.
