If I knew how to revert back to nougat without destroying my Samsung galaxy s8 plus, I'd definitely do it. I'm a little nervous about that. I just get the black screen too. This is my favorite and most used app. I'd hate to lose it. The other closest app is jet audio but it just not the same. Been using Poweramp for many years without a problem until this damn oreo installed on my phone. Using ATT if that helps any. I'm driving myself crazy trying to get it to work. It may be redundant, but any other suggestions would be awesome. Thanks fellas!
