Something completely different - that copies the form factor of the OnePlus Open exactly?
I don't why Google gets credit for just jumping on the bandwagon by making their foldable exactly the same as others, but Samsung's tweaking is given no credit whatsoever. I know the Z Fold 6 seems like a minor update from the Fold 5, but if you really compare it to the line over the years you will easily see how much the form factor has changed.
Personally, I don't understand why the outer screen needs to be a standard phoen ratio. I can see how that might be appealing for someone who uses a regular phone all the time and does a quick review of a foldable, but to me the inner ratio matters more, because I want to use the big screen for as much as possible. The inner screen ratio on the Pixel 9 Pro Fold is basically a square, which is optimal for nothing. So this outer ratio actually compromises the inner ratio in a way that makes no sense to me. I actually prefer the method that Google did on the original Pixel Fold, since its passport style design balanced the inner and outer ratio better.
I don't understand how the 1:1 ratio helps app compatibility, at all. No app is designed for 1:1. At least with the origjnal pixel fold, if the app didnt support landscape, you could rotate your device to portrait and it would work better. With a 1:1, it will always be wrong and there's nothing you can do to adjust it to be better.
