Coverage Mapper is designed to run in the background on your phone while you’re moving around, so that it can log the signal strength at various locations, for the purposes of generating an accurate cellular coverage map. A screenshot of the main screen is shown below. |
If the application says your screen is off, try restarting your device. Devices running Android 1.5 and 1.6 can have issues with detecting the screen’s state. If rebooting your device does not fix the issue, or you are using Android 2.1 or later, and you are still experiencing this issue, please request help on the forum or through the contact form. |
