How to get YouTube PiP on iPad
Best Android Video Players (2015)
Honestly, PiP on Android Oreo still feels a little beta. If you want a better experience, you need YouTube Red Subscription. You can still get PiP for YouTube but it isn't with the mobile app. You need to use the Chrome app, go on YouTube, set it to desktop, and then go back to the homescreen. It's kinda hit and miss.
There are also Android apps to watch YouTube via PiP but it feels clunky. A better way is to use the split screen from Nougat instead. That's why I ended up getting GPlayer because I missed MoboPlayer's pop-up play. MoboPlayer has wake locks I don't like. Feel like it's a Chinese rogue app. GPlayer's menu sucks as it's sensitive but doesn't wake lock.
I believe Apple doesn't want to offer split-view and PiP on iPhones yet because they want to differentiate their iPads to their iPhones. That kinda sucks because iPhones are generally more expensive. But a couple features to toss to iPad users who have been enjoying both for years and Android / Samsung Note owners even longer.
Some current iPhone owners in 2017: "Who needs split-view apps and PiP? Those look useless! All that matters is the X is beautiful and perfect!"
^ Useless features to some until it finally arrives. Just like gesture swipes years back that they finally implemented over the archaic home button.
In fairness, PiP isn't really all that especially on Oreo right now. It can get annoying with GMaps. I showed my homescreen using GPlayer and QuickPic with Futurama and Family Guy yesterday. I believe split-view with two apps is more useful. YouTube PiP on Android still feels clunky. Better off split-screen.
