I have been having issues with the GPS on my dx2. Whenever I try to use an app that uses GPS (like, Map My Walk or All Sport GPS) it indicates that it has no signal. These apps used to work beautifully, but not anymore. I have all of the GPS services turned on and I have the WiFi off. Any clues?
I had this problem twice, first time Verizon replaced phone, second time I called tech support he had me open settings - applications - maps, and clear the cache and data
Turning wifi on helps GPS location. Turn it back on. If that doesnt fix the issue, down load GPS Status. It will show you what your GPS is doing. There are some tools to help clear issues and reset location info also.
