Ever since my Galaxy S10 updated to the last Android 11, I have to have the screen display working in order to listen to a radio or podcast broadcast. This applies to TuneIn Radio, and also just going to a local radio station's listen live page. I used to be able to start to listen to a broadcast, turn the display screen off, and put the phone in my pocket. If I do this now, the broadcast simply turns off within about 10 seconds. If I want to listen, I have to find a place to put the phone, and leave the full display screen on, which unnecessarily eats battery. I suspected it was TuneIn Radio insisting I look at their ads (I have the free version), but it also happened when I went to the local radio station page. I found an article that told me how to fix it on a Pixel, but my Samsung doesn't have the settings options that they mentioned. Any suggestions?
