Uh-oh, looks like the iPhone Duo keeps crashing and users aren’t happy about it

The launch of the iPhone Duo, Apple’s highly anticipated foldable phone, is off to a rocky start. The phone was announced at this year’s Surprise and Shine event, with Apple promising that it had finally nailed a notoriously awkward form factor.

However, Bloomberg is now reporting that early Duo users are complaining of screen cracks “after only hours or days of use.” Some users have reported hearing a loud cracking noise, followed by the appearance of a crack. Others have reported display malfunctions.

404 Media also reported that early adopters faced “large creases in the middle of the screen ($2,000).”

TechCrunch has contacted Apple for comment and will update this story if it responds. The company told Bloomberg that it was “aware of an issue affecting the internal display of a small number of iPhone Duo units.”

Creating a functional foldable phone has been a long-standing ambition in Silicon Valley, but many models released so far have suffered from similar maladies. Apple has promised to have cracked the code, but these early complaints suggest it may not have fixed the problem after all.
