Google Chrome for Android brings Chrome Custom Tabs. When you click on a link to a website in an email, the email client opens that webpage within itself, in Chrome Custom Tabs.
Google Chrome Custom Tabs in picture-in-picture mode
According to the latest report from 9To5Google, the latest stable version of Chrome for Android (v122) lets you use Chrome Custom Tabs in the Picture-in-Picture (PiP) mode. For instance, now when you click on a link to a website in an email in Gmail and the email client loads the webpage in Chrome Custom Tabs, you can minimize that webpage into a PiP window, which will free up your phone’s screen to perform other tasks.
To use Chrome Custom Tabs in the PiP mode, all you have to do is tap the downward-facing button, which is located beside the back button at the top-left corner of the screen.
You can even resize the window according to your liking or move it from the left to the right of the screen. To go back to the fullscreen mode, tap the fullscreen icon, and to close it, press the ‘x’ button.
