Our flashyest feature is a photo-in-picture or PIP mode that lets you keep an application or video running on the corner of your screen that lets you browse other applications and jobs on your smartphone. At this time PIP only works with some of Google’s default apps: Chrome, Duo, Google Play, Maps and YouTube
First you have to make sure to enable PIP in settings. From the main menu, from the Settings menu, select Applications and Notifications and scroll to continue. Open the expand menu and tap access to the special application, and from there you will see a photo-in-picture option in the alphabetical list, where you can turn PIP on and off for each application. Once enabled, you can return to the home screen only from supported apps and PIP should be displayed in the bottom-right corner of your screen.
A catch but, so far. You can unlock only photo-in-pictures for YouTube, if you probably sign up for YouTube pop, then the application will probably use PIP most often. However, once I was able to work for Google Maps as well as two video chats with pipes at the start of the tour.
