Group tower on app map for less screen clutters and better performance. We recommend enable this feature make map loading faster.
Use new Android 4.2 Cell ID API
Default: off (Some latest phones have on by default)
This will use the new cellid API for Android 4.2 and newer phones. Cellid API 4.2 provide more accurate band information from cellular network and band information when phone support that. This doesn't work most Samsung, Huawei and Mediatek Phones before Android 8.
Some manufacture like Samsung not implement new Android Cell ID API in their phones. Also some phones have issues with Android 4.2 API. So we recommended check your phone support on our page. If your phone not in list, please contact to our support with email so we can add to list.
Please check your phone support here.

We recommended keep this enabled increases bad GPS locations or GPS data freezings. This will keep data accurate on map.
Minimum Recording Interval
The minimum number of seconds between data points.

This feature record all neighbor cells and tower info on 2G. On 3G and 4G it will continue recording all info what see you see on cell screen. You will not see neighbor tower's on 3G/4G because phone api not show their cell id:s example.

Qualcomm modem device
This is the modem device CellMapper will use. Application restart required.
