Firmware: 33.2.A.2.93/R3A Even when I set localization mode to 'device only' phone using agps - so I am charged for cellular data. Note that scanning settings both are OFF
Secondly: when I switch localization off and then on mode resets to best accuracy instead of remembering last value
When I am connected to WiFi and turn on for example speedtest app which using localization I see appearing localization icon and a second later arrow up/down on GSM signal icon. I am checking then my carrier app and I have connection and lost like 50-100kb. Same with any other app that are using GPS.
Again: mode of gps was set to 'device only' so no agps should be used. Scanning options are off as well.
Then use a different setting, there's 3 to choose from battery save mode is just as accurate nowadays and doesn't use any data as I use this setting myself.
Then set up n needs changing, is the background data for each app turned off individually if not this is why it's still using data. I have a limited amount of data each month myself on a contract I can assure you that if you use it on battery saver mode with the background data for each app turned off individually the device won't use any data at all I unless you tell it to and my location settings are on 24/7
