This app will help you access hidden network settings for forcing band selection on Samsung phones. Some example use cases may include, but not limited to:
- Discovering new 4G LTE / 5G NR bands in your area
- Avoiding congested bands by manually selecting a well-known uncongested band
- Crowd sourcing contributions (e.g. CellMapper)
There is also an option to access "More Network Settings", which contains dual SIMs settings for VoLTE, APN, Wi-Fi calling, etc, when supported by your device and carrier.
Tested on Samsung devices running One UI 2.0 and up. Compatibility verified by the community on Galaxy S8, S9, S10, S20, Note8, Note9, Note10+, A30, A50 J6,...
