Couple of months back, a game developer had observed a problem with iPhone 5′s touch screen. They’ve observed the iPhone 5 screen stops responding to touch inputs when you slide the finger across the screen in quick successions.
We were also able to replicate the issue on the iPhone 5 and the iPod touch 5G, which indicated that the problem was with the 4-inch display.
As you can see in the video below, iPhone 4S units running iOS 6.0.1 and iOS 6.0 didn’t seem to be affected by the bug, whereas iPhone 5 units running iOS 6.0.1 and iOS 6.0 exhibited the problem, which indicated that it was a hardware related issue.
At that time, it was widely speculated that the problem could be with the new in-cell display used in iPhone 5. The in-cell display technology integrates touch sensors into the LCD, which eliminates the need of a separate touch screen layer. The absence of a separate touch screen layer not only helps to make the screen thinner, but it also improves the quality of displayed images. Colors get a boost, too, with color saturation that’s 44 percent greater than before.

While many of you may not have noticed the problem, it was seen as problem for users who play games that need quick diagonal scrolling and swiping motions.
But it looks like you won’t hit the issue in iOS 6.1 as Apple may have fixed the bug or at least improved things as pointed out by MacRumors.
Several readers have noted that an issue with rapid diagonal swiping on the iPhone 5 and fifth-generation iPod touch resulting in loss of touch recognition appears to have been fixed or at least improved in iOS 6.1. Not all readers have experienced improvements, however, with some indicating that performance remains the same under iOS 6.1.
I couldn’t replicate the issue on my iPhone 5 and iPod touch 5g on iOS 6.1, but as MacRumors points out some of the their readers are still able to replicate the problem.
Let me know if you’re still able to replicate the issue after upgrading to iOS 6.1.
