I dont know why I cant find any information for people who want to connect their phones to stereos. I was thinking about buying the new p20 pro but i have since learned that it has no headphone jack. So I can use the adapter that comes with it to connect it to my stereo but i cant charge at the same time. Is there a solution to this problem?
