UMI SUPER GPS PROBLEMS

saikee

I confirm a stock UMI Super, assuming no defect from the assembly, will be as good as a consumer grade Sat Nav.  This claim is based on having used UMI Super side by side with a Tom Tom over a 800 miles round trip journey in UK.

I also confirm that I have installed the App "GPS test" which updated my GPS files (instead of using that provided by the factory as my phone is in Europe).  The Sat Nav App is Sygic which is a paid version.  

There are many causes that can lead to poor performance of the GPS system.  It is possible some free Sat Nav versions may not be fully updated and compatible with Android 6.  The factory version of the gps files definitely need to match the correct zone.  UMI Super does have a evidence of bad assembly in the early batch of the product release.

Finally a 3 ft accuracy GPS system may be tough target from a US$200 phone.

I used GPS system when it first came out and cost about 7 UMI Super.  Now I also run a Vernee Apollo Lite that has a better GPS performance than UMI Super but otherwise same spec as UMI Super.   I do substantiate my UMI Super, a stock phone delivered 27 July, has performed everything impeccably including its gps functionality.

1. Go into your phones "EngineerMode" (most Mediatek devices have this) by typing *#*#3646633#*#* in ...

Of course this doesn't improve the GPS at all. Looks like just another case of a placebo "solution."

I tried this placebo solution too and doesn't work.
I didn't open the cell phone for aluminium or bend GPS solution...
I was waiting for a solution from UMI devs, but it's hard any answer by UMI.

And placing a copper foil instead of aluminum. Does improves signal more ?

I don't have to explain.  The photo posted shows the accuracy on an Mtk chipset deca core so it's newer with 3ft accuracy.  
My oneplus One with a snapdragon 810 chipset also has the same accuracy  and that's older.

The UMI Super does not come near with GPS accuracy -  nothing to do with age or manufacturer. -  great if your phone is working but the major of the forum users have GPS accuracy issues and that's self evident.

GPS will roam randomly then set on a location then roam randomly again,  this is the issue people are having.  If your phone is working then there is no need to try and prove your point, it's not relevant.

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.
