iPhone Duo crease put to the test revealing some interesting quirks

The iPhone Duo has been put to the test by various social channels and media outlets. While most have tested the hinge’s durability, some others have focused on the screen. Some of the test videos for the screen show durability when compared to other foldables, as well as some other interesting quirks.

The video posted by Tim Pan on YouTube tests the crease of the iPhone Duo after 10,000 folds. It starts off with 500 manual folds, after which the crease becomes visibly deeper, but not too different to the touch. Then, after 10,000 folds at -4-degree F temperature, the iPhone Duo’s crease deepens further. That’s to be expected, and it should also be noted that this isn’t representative of real-world use. The hinge stays strong, however.

The video also shows some software issues when folding or unfolding the phone. When slowly folding the iPhone Duo, the screen would sometimes twitch as if it were starting the folding animation. Auto rotation while opening the phone was also sometimes glitchy.

While the nano texture finish prevents glare, it doesn’t fare well with oil and grease or certain makeup. Regular fingerprints are easy to wipe off.

Another review video, this one by HTX Studio, showed that the iPhone Duo’s crease became deeper than that of two other foldables after 3,000 folds. They also found that the screen around the crease is much softer, as recently reported by leaker Ice Universe on X.

Another video posted by the same leaker shows someone peeling off the matte film to reveal inconsistencies on the inner screen. There are wrinkles that seem to be covered up by the matte film. Comments on that video have stated that this is a common occurrence with foldables.

Overall, the iPhone Duo seems to be a solid first foldable from Apple, but at the $2000 price point, are these issues harder to ignore? Or are these “issues” not issues at all?
