In Chrome OS and Chrome for desktop (Chrome for MacOS, Chrome for Windows, and Chrome for Linux), if you long press the back arrow while you are on a browser page, you will get your recent browsing history for that tab. It is a handy feature. On Android however, when you long press the back button on your phone while in Chrome you get… nothing. You can press the button as long as you want but it will just take you back to your previous page.
That looks to be changing in Chrome 70.
A new flag has popped up in the Chrome for Android Canary app, which is based on Chrome 70, that allows you to enable the back button on your phone to display you recent tab history.
