I don't understand how 'swipe from the left' can be used as a universal back gesture. Isn't it the case that most apps use that gesture already to open a menu?

Then again I still miss having physical back and home buttons since I upgraded to a newer android phone. It would be nice if manufactures added more buttons to the side of the phone so the other fingers have something to do.

You can swipe at an angle (around 45° up or down) to open the menu, and straight out to go back. Not very intuitive/discoverable, but works pretty well once you get used to it

That's also discussed in the blog post I linked. tl;dr: Only a small subset of users (3-7%) uses a swipe gesture to open these menus (all others use the hamburger menu) and these users have to adapt now to do different kinds of swipes for opening the menu and invoking the back gesture.

Android has 1.3 BILLION users. 3-7% is tens of millions of users

After reading your comment, I went through my most commonly used apps and found that they all have a hamburger button in the top left corner that brings up the same menu as a swipe from left gesture. Somehow I never noticed those buttons before, leaving me feeling a bit spooked. How is it that something I look at dozens of times a day could go unnoticed for so long?

I had the inverse reaction: I discovered that all these apps support swiping from the left. At least the hamburger menu is visible - there is nothing really advertising the swipe gesture.
