Samsung Galaxy S, T-Mobile Vibrant, AT&T Captivate GPS Issues

2010-07-28T22:37:40Z

Users of the Samsung Galaxy S phones (T-Mobile Vibrant & AT&T Captivate) may experience poor GPS results due to a GPS bug. Samsung and your carrier will provide an OTA fix soon, but until that time you may fix the issue by following these steps:

Disable “Use Wireless Networks”. Navigate to Settings > Location & Security > uncheck the box next to “Use Wireless Networks”
Go to the phone and dial *#*#1472365#*#*. This step throws you into LBSTestMode menu.
In the LBSTestMode menu, change “Operation Mode” to MS Based.
In the LBSTestMode menu, find “SUPL/CP Settings” and change the SERVER & PORT to supl.google.com and port 7276 (DO NOT use www. in front of supl).
Reboot you phone (turn off and on).
Enable “Use Wireless Networks”. Navigate to Settings > Location & Security > check the box next to “Use Wireless Networks”.

Feel free to email me if you have any questions.
