A fix for the Samsung Galaxy S GPS problem

t-mobile-samsung-vibrantOn Thursday I went to my local T-Mobile store and picked up the new Samsung Galaxy S to replace my damaged Google Nexus One.  I am usually reluctant to early adopt any new gadget, preferring to wait at least a few weeks to read about any issues or complaints other users might have.  Being eager to replace my Nexus One with an Android-powered device that wouldn’t suffer obsolescence in six months, I went ahead and took the plunge.

I was thrilled with the brillant Active-matrix OLED (AMOLED) display.  The T-Mobile version of this handheld is called the Vibrant and the image quality is just that.  The device included a copy of the movie Avatar and it looks amazing.  I also liked the thinness and light weight of the device.  The device is also fast.

Given all my excitement, I soon found myself crashing into a brick wall of disappointment. The GPS utterly sucked.  It took seemingly forever to get a GPS lock if I was lucky. Often I couldn’t get a lock at all, inside or outside. My buyer’s remorse intensified. This was a big deal.  Using my previous two phones, the HTC Dream and the Nexus One, I found GPS to have become indispensable, especially when navigating in the car or geeking out with augmented reality apps, not to mention foursquare or Google Sky Maps.

Frustrated, I started Googling to see if this specific unit was just a dud off the factory line or if other users were experiencing the same thing. Sure enough, others were complaining and I came to regret my early adoption.  I stumbled across across rumors that Samsung was preparing to release a firmware fix for the issue.  This gave me the hope that the hardware itself was fine. I can deal with a fixable software problem.

It turns out it is just software that can be corrected with a small firmware change anybody could do themselves. I found this fix on XDA Developers forum.  So far it seems to have done the trick.

  1. Turn Flight Mode on
  2. Dial *#*#1472365#*#* which brings up the firmware menu ***UPDATE*** The sneaky bastards at Samsung changed this.  Now use *#3214789650#  Hey Samsung, you do know that if you change this again, we’ll figure it out.  Why bother?
  3. Under Application Settings change Operation Mode to MS Based
  4. Under SUPL/CP Settings change the Server & Port to supl.google.com (no “www”) and 7276 respectively
  5. Reboot
  6. Turn Flight Mode off

Ahh! My buyers remorse has vanished and I love this phone again.

In case you need to restore the default settings, they are:

Operation Mode: Standalone
Server: www.spirent-lcs.com
Port: 7275

I hope this works for you.

    I'm having the issue still after this fix, what worries me most is that I've not seen anywhere that Samsung have commented on this problem, what happens if it turns out to be an hardware issue.

    The effect of the 'fix' is simply to reduce the time to acquire the satellites during initialisation by providing a valid almanac (timetable) of there whereabouts.

    This 'fix' does not address the chronic GPS problems being reported: namely the inability of the SGS to maintain lock and keep the accuracy at anything like acceptable levels.

    I think we will have to wait for a firmware fix

    Hey Mike,

    I’ve come to realize that you are right. I’m ready to switch phones again. My dissatisfaction with this phone has reached critical mass.
