Samsung Galaxy S GPS problems. http://www.engadget.com/2010/08/17/s...nd-what-to-do/
Hopefully they can fix that problem with a firmware update.
One of the most annoying things about my BlackBerry Storm 9530 is that GPS does not work in Google Maps. My Storm was my first smartphone and I was really excited about GPS on my phone but it has been so disappointing not being able to use it in Google Maps.
