Maybe it's a special problem/wish focused on Switzerland ... Most mobile provider in Switzerland include mobile broadband 4G/LTE with a volume-limitation of the usage. 4G/LTE is nice for apps needing fast connection. But it's not necessary for streaming audio/radio. It's quiet uncomfortable to switch the smartphone's general bandwith for streaming audio/radio to prevent from reaching the volume-limitation too fast. Therefore it would be nice to be able to use the app settings to configure which frequency band (4G or 3G) should be used when streaming with mobile broadband.
