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.

The iPhone's Touch Screen Accuracy is 'Extremely Bad' Near the Edges [Report]

"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.

You are correct, it is terribly inaccurate POS and will switch to Samsung as soon as the last 18 payments are made for this piece of junk

Isn't the iOS ignoring the accidental touches near edges, while grabbing the device?

I actually do notice bad sensitivity near the top left corner, on my 5S

It's probably a Samsuck robot! I don't notice any difference with typing between my 4s and my 5s.

A accuracy limit of +/-1mm is ridiculous.Human finger is much bigger, so 1mm does not make a difference which actually effects humans in real life.

Yikes maybe I'm too human. Please pardon the typos.

Welcome to iPhone

I love this site so don't know why you say it's dead?

Debip - October 26, 2013 at 3:37pm

This site's quality is dead.

I noticed my iPhone 5 is less accurate than my prior iPhone 4.

sidewinder - October 26, 2013 at 2:23pm

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.

Johnny Cage - October 26, 2013 at 2:12pm

This a bunch of bullshit... My 5s is just as sensitive as all my other iPhones. Everyone that has owned an Android knows you can't compare.

Vanja - October 26, 2013 at 2:11pm

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.

Galaxy touch function weakens after a while and i never have had this experience since my very first iphone. Have tried SG S4 and its now good enough.

Sharon Nathaniel - October 26, 2013 at 12:57pm

I don't know why every other person on earth is trying to prove that Apple is crap.

Andhu - October 26, 2013 at 5:22am

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.

Guys, it's so simple! The robot isn't touching it properly!

matrixmaniac - October 26, 2013 at 8:41am

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....

Gio - October 26, 2013 at 12:32am

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.
