I think I've found a software bug in the Droid Charge related to GPS altitude and need some volunteers to help verify the bug. I've tried three different apps that all report the same wrong altitude. The altitude is off by a factor of ten! I live at 5600 feet and the DC reports roughly 560 feet. When I drive up to 6000 feet the DC says 600 feet. One of the app developers was kind enough to send me a custom version of his app (AndroSensor) that multiplied the altitude by 10 and that made it display the correct altitude. Has anyone else noticed the same problem? The error doesn't seem to affect the accuracy of navigation or google maps so unless you specifically look at the altitude parameter you may not know there is a problem. The three apps I've tried are: GPS Test, AndroSensor, and GPS Essentials. All are free. If any DC owners are game, please download one of these apps, or any other app that reports GPS altitude, and relate your results. I'm especially interested in hearing from owners who live at an elevation of three hundred feet (one hundred meters) or higher since if you live near sea level the error is smaller and may be within the margin of GPS accuracy. Useful information to include in your results are: actual altitude, reported altitude, hardware version, firmware version, and build number. The last three are found in Settings...About Phone. If we can verify other Droid Charges have the same problem as mine, hopefully we can get Samsung to fix it in a future update. Thanks all.
