Note 9 cutting off my radio station online

[Dtc2019]

My phone keeps shutting off the radio station. Close out the screen and 4 or 5 minutes later the radio shuts off (online radio)

I have tried multiple ways but the radio shuts off. Even if I leave the screen on it shuts off in 0 to 15 minutes. Its maddening . I want to take a hammer to the stupid phone

I was having just this same issue with another app. Wrote the Dev and turns out it was my fault. Go to Device Care>Battery and turn off put app to sleep for your radio app.

Yeah one day the phone told me that the app was using background power and asked if I wanted to put the app to sleep. I thought, Oh just this time, but no it turns out to be always and forever until you change it. LOL
