Apple iPhone 5s and 5c touchscreen test shows surprising inaccuracies, Samsung Galaxy S III way more accurate

The Apple iPhone is the phone that brought high-accuracy capacitive touch screens to the mass market, but since then everyone has jumped on the bandwagon…

Shocking.. That to on an iPhone....!!!!
That is why icons on iphone are so huge, so that even inaccurate touches can be registered....

this is true... i have noticed inaccuracies on my iphone 5 as well... tbh i just ignore it because its not an issue that keeps me from completing phone tasks in a timely manner. An extra touch or two is what i deal with.

iPhone is not 100% perfect. but its still an iconic device.

1.) You are not touching it right
2.) You really don't need q,o, and p anyway.

I own a GS3 and work with iPhones daily. I find that my GS3 keyboard had gotten terribly inaccurate after an update earlier this year. Not sure why. But in contrast, whenever I work with an iPhone, I find it much more accurate on the keyboard despite being smaller.

Apparently what this test doesn't take into account is that Apple calibrates the different areas of the touchscreen to respond to different angles. Humans don't necessarily touch the screen at the same angle at every point of the screen (unlike the testing robot). If the test had actually calculated the different angles the touches were "off" it probably would have been in a predictable pattern. The SIII just assumes you're a robot.

Basically this.

I own a 5S and a Note 2. I have ZERO issues with my iPhone 5S, so I am kind of surprised to see so many apparent iPhone owners on PA (thought this site was mostly droid) who seem to be having such major problems. I tried all of the so called 'problem areas' such as with P and Q etc and it was fine every time.... so urm.... what is mine special?

If such a detrimental flaw existed (the iPhone 5 has the same screen as the 5C and 5S right...) im sure it would have been splurged over the media as 'TouchGate' by now.

Was this test by OptoFidelity sponsored by Samsung or something?

Wow, I knew there would be a ton of rationalization - the study was paid for by Samsung, the test facility just hates Apple... but this takes the cake.

So Apple had offset the screen to account for the angle you touch the screen. So it's actually more accurate. Got it.

Of course, this means that Apple not only make both right handed and left handed iPhones, but also gets a personalized measurement of each users thumb and customizes the screen to it.

In fact, the iPhone itself probably scans your thumb in 3d and not only gets it's dimensions but which side of the phone it's on.

Those two trying to rationalize this needs to look at the 3 pics again.....

For the iPhones its almost identical in both screen shots. If what stealth said is true....wouldnt there be some green in other areas if Apple really did calibrate different areas of the screen?

I mean seriously.....cmon. From the article:

"Interestingly, iPhones were most accurate in the bottom part of the screen - exactly where the keyboard is located, while in other parts of the display and even around the edges of the keyboard they do not register touch accurately at all."

Logic says that Apple calibrated the area where the keyboard is more so than other areas of the screen.

Cmon man.... Although.....does anyone with an iPhone 5s and 5c notice issues playing games since games could use more areas of the screen?

iPhone is the most expensive phone, but the touchscreen quality is like random cheap Chinese phones.

so Apple do have highest response time though apparently? looking at some of the comments it almost appears apple sacrifices touch accuracy in favour of response time... EDIT: suppose I wouldn't be surprised if they were taking expected angle into account also though, that would have to be tested.

These tests mean nothing because the iPhone actually registers touches slightly above the centre of where you put your fingertip, an intentional compensation to make it prefer the 'tip' of your finger, rather than the middle of the contact area.

Try tapping buttons with your iOS upside-down (with orientation lock on) and you'll see how different it is. Apple offsets the touch so that your eye-finger-button line is straight on the target

Riiiiiight. Apple knows which hand each user uses, how long each users thumb is, and what angle and distance they hold the phone from their eyes. It probably even compensates for when you tilt the screen slightly to avoid a glare, right?

Can't innovate my ass.

For me this is hardly surprising. I know, however, that for a lot of people this will be an eye opener.

Maybe after awhile people will stop believing that apple products are made with unicorn tears and constructed by magic fairies and see them as they see any other product by the likes of Samsung, Sony, HTC, Motorola, etc etc.

So they can register the wrong touch coordinates much faster. Awesome.

In the Iphone, when the ads are displayed (In apps) with close button marked by 'X' on the top, I noticed that you need not be accurate to touch exactly on the X to close the ad. Even if you touch in the vicinity, it registers your touch and closes the ad. I see Software intervention here as the X are very tiny.

Just upgraded from the iPhone 4 to the 5c and noticed on numerous occasions that when the screen fades down to go into lock screen, regardless of how many times I tap the screen it just blanks out and locks anyway!
