Google has optimized a bunch of its own apps to work in the Fold’s unfolded tablet mode, and they’re great. Gmail, YouTube, Photos — they all make use of the full screen by putting information in sidebars and vertical columns. Chrome has a desktop-like interface, complete with tabs at the top of the window and the ability to load the full versions of websites. Google Meet readily moved a tiled view of attendees to the top part of the screen when I set the phone up in an L-shape, sliding the controls to the bottom half of the display. I didn’t have to fiddle with anything — it just worked.

A lot of third-party apps don’t take advantage of the whole inner screen, though, which stinks. Instagram is just a phone-sized app with black bars on either side. Same with Twitter, Facebook Messenger, and even Google-owned Fitbit. You can double-tap the blank space on either side to quickly slide the app to the left, right, or middle, which is nice. TikTok plays its vertical videos in the middle of the screen but at least uses the extra space on either side to move all the text that’s usually right on top of the video out of the way. Even so, it feels like a lot of wasted space when you’re not watching a video or multitasking.
