That’s not true I used to use picture in picture with my Samsung galaxy s6. I could Skype with my girlfriend long distance and watch a movie with her in the background. Or I could let a movie keep playing during a boring part and respond to text or read an article and let the movie keep playing. It’s very frustrating they don’t allow us the option to use picture in picture if it’s too small real estate for you that’s fine but for me there’s plenty of real estate especially on the iPhone XS max which is plenty big to put a small 1” x 1” size picture in picture or a picture in picture that I could make bigger or smaller just like I can on the iPad.
