How to get Picture in Picture mode on any smartphone
KMPlayer
KMPlayer is a decent video player for Android smartphones with a bunch of unique features which other apps or the default video player don’t provide. And the best feature is the Picture-In-Picture (PIP) mode which lets you view the video in a popup window. If you own an Android tablet then this app will let you do more than two tasks at the same time; you can keep two apps in a split view mode and watch the video in a small pop up window.
KMPlayer is also available for other devices as well; Windows and Mac OS (Beta). It comes with the built-in codec which can play any type of video file type. This app is free to download from the Play store, and the developers also released a KMP VR Mobile App. Download Now
