I had installed an app via the market, but something in it was not programmed correctly because it would not release the GPS when the app was closed, even if forced closed (aka killed) my notification bar would still show that the phone is trying to get my location. The only way I could get the phone to stop was to reboot. I uninstalled the app since it was clearly not functioning properly. The problem I'm having now is that if any app uses the GPS for more then a lil over 2 min. the GPS locks up/crashes and again the only way to get it working is to reboot the phone. GPS is clearly off, yet is also still in the notification bar So, my question is can a "bad" app corrupt the software/firmware that makes the GPS function? Even if the phone is still stock, non-rooted. I also ask due to the well known history of this phone and GPS, but prior to this app my GPS was one of the very few that ran perfectly. P.S. I'm not all to worried about how to "fix" it since I know the typical methods, and if all else fails I'll just flash a custom ROM.
