While the app and site try to filter this bad data, there is not much that can be done to fix it. As more data is gathered, these errors will slowly decrease until the map becomes more and more accurate. | While the app and site try to filter this bad data, there is not much that can be done to fix it.

The frequency can only be retrieved with a BlackBerry device for certain. Certain Windows Mobile devices (Qualcomm based HTC devices) and all Windows Phone 10 device also support this. For Android, certain Motorola MotoBlur devices (Motorola Charm) support this; as well as most Android 7.0 or higher devices. | The frequency can only be retrieved with a BlackBerry device for certain.

In Android 4.2, the CellID API was re-written to ensure data is updated somewhat atomically to avoid bad data. Unforunately, some manufacturers, notably Samsung, have chosen not to implement this new API. You can see a list of known supported and unsupported devices on this page: [https://www.cellmapper.net/Android_4.2_CellID_Support Android_4.2_CellID_Support]] or [https://www.cellmapper.net/Tested_Phones Tested Phones] | In Android 4.2, the CellID API was re-written to ensure data is updated somewhat atomically to avoid bad data.
