Just watched a couple hands on reviews. There are no bottom buttons on this. Is that a Pixel standard?
How the heck do you go to home from where you are? Or open the multi windows you had been to to go back to a previous window?
This has me a bit concerned and might take some getting used to.
Seems to be one of the trends with some phones. I'm using a LG G4, and the "bottom row Home buttons" are generally "always on" in the home screens. In the OS Settings, you can customize each app to have it on or off. If it's off, you can swipe from the edge inward to reveal it, and then tap on what you need (e.g. Back, Home, app switcher, extend notifications from the top, etc.).
I've used a Samsung Galaxy s9, and same deal here. There's an additional feature here where no matter what app you're in, you can always press the space where the home button is to take you Home, but it has to be BOTH physical pressure and capacitive. So just tapping on that spot doesn't contain the former. Using a plastic stick and pressing on it doesn't contain the latter.
I've played around with store models of the iPhone X, and same thing. There's a "grabby bar" at the bottom that if you flick up, you get options there. You need to flick it in particular manners to switch between apps or return Home.
With the above, you do maximize the screen real estate which is nice. It may seem scary, but it's something you should get used to. Hell, I had similar doubts when I switched to a flip phone to a smartphone (Galaxy s2)... No physical buttons for the numpad! That doesn't seem like it could possibly work! :x Yet again when I lost the physical home button going from a Galaxy s4 to the LG G4.
