Apple’s new 4-inch iOS devices — namely the iPhone 5 and the fifth-generation iPod touch — appear to be suffering from a strange glitch that means they struggle to keep up with rapid touch inputs, particularly when scrolling at a 45-degree angle. The problem, which isn’t present on older iOS device like the iPhone 4S, is demonstrated in the two-minute clip below.
The issue was first discovered by CMA Megacorp, which highlighted the problem on Twitter:
Slide finger back and forth diagonally on screen, input events drop out or stop altogether.
Now, I know exactly what you’re thinking after watching that video. Who on Earth scrolls like that on their iPhone anyway? Well, you’d be surprised. While it’s unlikely you’d ever use apps in this way, rapid gestures aren’t uncommon in iOS games. If you’ve ever played a game like Fruit Ninja, you’ll know what I mean.
What’s strange — and worrying — is that the issue only seems to be present on the iPhone 5 and the fifth-generation iPod touch, suggesting it’s a problem with the new 4-inch displays Apple uses in these devices. The fact that it isn’t present on older devices, or even the new fourth-generation iPad, suggests it may not be fixed by a simple software update.
Have you encountered any problems with gestures not being recognized while gaming on the iPhone 5 or fifth-generation iPod touch?
