I have a brand new phone. It constantly drops the location services entirely. The location services will work for a few miles in navigator, then stop. Same with google maps, and every other GPS enabled app. I either have to toggle location services on/off in the settings, or do a soft reset, to get the GPS working again. I downloaded the "GPS test" App to check the function, and ran all available updates. I have google location services unchecked. Sometimes the location works for a while, and then a few hours later it no longer works. One of the reasons I got a droid in the first place is because I liked google maps.
Separately my phone just started doing the purple screen on calls. I made the jump from iphone and am starting to question my decision. Apps that work flawlessly on iphones are buggy on my new droid.
