Android/Troubleshooting
The Internet is obviously full of information regarding solving problems that you may face using Android devices. However, since some issues are especially important for mappers, below are some solutions to some of these problems.
GPS fix issues
Some people have problems getting a GPS fix on their Android device. These problems can start immediately when using a new device, or after using the device for some time.
A discussion on the HOT list provides two solutions to these problems. Both fixes seem to relate to AGPS information:
- Change the NTP server in the 'gps.conf' file on the device [1] , either manually or with an app that does it. Rooting is required for both options.
- Use an app (GPS Status & Toolbox = Free) to download up-to-date AGPS data [2] (download link). No rooting required.
- Improving GPS-antenna performance (hardware "hacking").
An alternative to the build-in gps device and antenna could be a bluetooth capable GPS-mouse. GPS-mouses are build for a special purpose: getting GPS-signals and delivering this to a) a tracking unit (typically built-in) and b) and deliver GPS information to a connected device like PDA, smartphone, tablet.
Designed for basically one purpose and not restricted by the flat formfactor of todays smartphone they have a better chance to deliver good results. Being small and lightweight they can easily be mounted at a place with good receiving condition (helmet, shoulder, ...) whereas a smartphone will need some interaction and is thus more restricted than a GPS-mouse. --EvanE (talk) 12:37, 11 August 2013 (UTC)
The Nexus 5 device loses gps signals if the back cover is not completely snapped in place. If the Nexus 5 is unable to obtain a gps fix, check the back cover, even the smallest portion of the back cover not snapped in place will cause the gps to fail. Glassman (talk) 14:29, 8 September 2014 (UTC)
