Does GrapheneOS run on tablets? I don't see a whole chat app (shown in the example) fitting on my phone screen alongside something like a web browser, and the screenshot is from a square screen

It's complicated. The Tensor G2 Pixel tablet was a solid device, and you can still buy it new from Google (with no choice on color or size in my country), but production has been discontinued and the two direct generational successors were canceled, in sequence. First it was skipping a generation, then it was canceling it entirely. The rumored "Pro" version also appears to have been axed.

I've used mine daily since it came out, and it's a great experience. I'd recommend picking it up for anyone who wants GOS on a larger screen. An iPad it isn't, but my iPad Pros have sat almost totally dormant since I got it years ago.

It lacks horsepower compared to the latest Pixel Pros, but that hasn't been a practical concern in anything I've done with it so far.
