To import a V3.0 (decimal cell data and coordinates without characters) CLF file, remove all comment lines, rename it to import.clf and copy it to /sdcard/gmon/ then start import CLF from menu.

You can log GSM or UMTS RX levels into a kml file for Google Earth or a csv file. There are 5 color groups for different levels. These levels can be defined by the user in the settings menue. This file is saved into the gmon folder on the sdcard or external memory. When the log is running, the G-MoN Notification Icon changes color to red. 2G/3G logging does not work when the screen is off!

The app requested permission to turn my WiFi on and got itself into a loop. The only way I could get rid of it was to reboot the phone. Clicking both 'accept' and 'deny' did nothing to remove it.

Please update this for Android 9 and 10 as it keeps complaining that it was built for an older version of Android and won't work properly.

Forces my phones WiFi on so impossible to do correct volte calls. Does anybody know why this would be happening and know a fix

A. G. u. Oct 7, 2017     

The app might be good, but preventing you from exiting when you don't want to give it a permission by repeatedly throwing a permission prompt screen that prevents interaction with the phone in normal ways earns this app an uninstall
