You can (sort of) try out Samsung's new foldables on an iPhone
Well, as far as advertisements go, this one is certainly unique.
Samsung's "Try Galaxy" iPhone experience (I hesitate to call it an app because it's just a Safari page you pin to your home screen) has been updated with new features meant to showcase the Z Fold 5 and Z Flip 5 foldables. In a blog post, Samsung made it seem like you can simulate the unique features from its two recent foldable phones using an iPhone.
In practice, it's a little less interesting than that.
Once you get "Try Galaxy" working on your iPhone, it shows you a Samsung Galaxy UI where every button serves to advertise Samsung products to you. For instance, opening the "camera app" plays a bunch of videos showing you how photography works on Samsung's foldables, rather than really letting you try anything out. That's fine, but it's not really a demo in any meaningful sense.
The one thing that does seem interesting was also out of my reach at the time of writing. You can connect two iPhones together to create a facsimile of a Z Fold 5, though it seems like all that does is show you video demonstrations of what using a foldable is like. Unfortunately, I didn't have another iPhone on hand, so I got this bummer of an error message instead.
Ah, well. You can't win 'em all. Still, if you have an iPhone (or two) and want to see what Samsung's recent stuff is all about, go ahead and give "Try Galaxy" a shot.
