A study by OptoFidelity has found a significant lack of touch screen accuracy with Apple's iPhone 5s and iPhone 5c displays. The company used its Touch Panel Performance Test to compare the iPhone 5s, iPhone 5c, and Samsung Galaxy S3 smartphones.
OptoFidelity Touch & Test is a test platform for touch device testing. PDT stands for panel performance device level testing. OptoFidelity Touch & Test measures the touch panel accuracy. This tester includes a robot with an artificial finger. The tester compares the coordinates of robot to the coordinates captured from the touch device
The company tapped each phone across the screen and compared the actual touch position with the reported coordinates. The PASS/FAIL limit for their accuracy test was ±1 mm. A green point indicates pass and red one indicates fail.
"Results were highly surprising. According to the results, iPhone’s touch performance is extremely bad near the edges and there is also a different offset on the top of the screen compared to the lower part of the screen."
OptoFidelity says the touch accuracy is much better in the Galaxy S3 which will result in less typing errors. For example, on the iPhone, the keyboard letters Q, O, and P are on areas which failed the accuracy test.

Hmmm. I've actually noticed this in my own 5S. Typing on the keyboard pisses me off more frequently than it used to and I find it harder to highlight words quickly and precisely. This is true. & I'm not an apple basher; I've not owned a non-iPhone since the original came out. Now that this is out I hope they do something about it.
Hummm, another Samsung "sponsored" company? Anyone who used an iPhone and any Android device knows iPhone (even the "2G", classic iPhone) is far superior in touch.
I use both IPhone (1st choice) & Samsung (I have to use it as a technician). Typing tells us how accurate is the touch.. I've never made a mistake while typing on my iPhone unlike Samsung.. THIS IS A BIG FAKE. iPhone touch is more accurate then anything ever build..
My cherished friend and crusader "Crapple" ... Please, please refrain from your exuberant posts, while we love your passion with most pleasure ... you are making us look very imprudent indeed.
Yeah, makes perfect sense: The robot touches it perfectly for a ROBOT, so it works best on ANDROID...
So, all robots buy Sumsung... I'm human though... I'll stay with iPhone....
The only times I hade accuracy problems where when I was trying to type after few beers, wonder if was the touchscreen or the beer...can you get DUI,for typing drunk..... hahahah Just wanted yo post something useless as all the others Samsung lovers here.
