Try restarting your device and contact support@mapware.com if the problem continues.
In cases where the software is failing to function properly, try resetting the device, beginning by unplugging the controller from the tablet, turning off the drone and controller, and then reconnecting and turning everything back on. Sometimes this seems to cure random odd behaviors.
Make sure that you have the latest version of Mapware Fly installed on your device. We release updates frequently, and it is possible that the error was addressed in a recent patch.
If the problem persists and you do receive a crash, please send an error report to support@mapware.com with the device and drone you are using, and any other information about the situation so that we can attempt to reproduce the error. This helps our engineering team address the issue for our next release.
