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

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, and latest tests show that Apple devices like the iPhone 5s and iPhone 5c actually have less accurate touchscreens that competitors like say the year-old Samsung Galaxy S III.

A new study by OptoFidelity for the first put smartphone touchscreens to a test by a robotic hand that touched the display at specific points and then compared what the phone actually registered. 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.

In stark contrast, the accuracy of touchscreens like the one on the 2012 Samsung flagship, the Galasy S III, proved great all across the screen - top, bottom and center, and not just at the part where the keyboard is located.

Green areas show accurate touch registration, red once show deviations.

Green areas show accurate touch registration, red once show deviations.


The revealing findings are backed up by charts and seem more than reliable - after all it’s a robotic hand that OptoFidelity used and not a shaky human hand.

The moral of the story is simple. Be more careful when you type on the iPhone keyboard, especially around the edges where the Q, O and P buttons are located. Don’t be too surprised if most of the typing mistakes you make occur there! The digression might look tiny - it’s just around 1mm - but let’s not forget that those buttons are not all that large either.

Here are the areas around the edge of the iPhone keyboard that have inaccurate touch response.

Right below is a video demonstration of the equipment used to test the screen accuracy. Have you ever noticed you have trouble hitting those buttons right?

This goes right back to the screen "response time" article. If the effect is not noticeable to the user, it doesn't matter at all. Clearly it isn't noticeable. I've never heard of reviews or users saying the touch screen is inaccurate on any top tier phone.

iPhone 5 suffers from this issue...

Really? That kinda changes my whole comment/thought process. I admit I don't use an iPhone but, this is the first I've ever heard of it.

I also think you're a slight troll and take anything you say with a mountain of salt, so, there is that too.

lol I don't know about PapaSmurf, but I can confirm that the iPhone 5 and even 5S suffer from this issue. I've had both and still like Apple products overall, but I've been bothered by this quite a few times. I've always thought I was hitting wrong and therefore the issue came from me, but I haven't encountered this problem on Android or WP devices.

It's strange because on the other hand, I've always praised Apple for their touchscreen technology, being somewhat more responsive than others, but this one is pretty annoying...

Damn. I'm seriously shocked. Apple, this is like touchscreen 101. Where you click needs to be exactly right. Fix it.

Trolling tendencies!!! Haha. At least you don't go on fanboy rampages and you always stick to the subject. I'll give you plenty of credit for bringing relevant info to the table, and for that, I thank you.

iPhone 5 has problems registering touches. Surely I wasn'tthe only one that experienced this issue.

+1 to you sir.

Two friends I know who own an iP5 also have problems with touch accuracy around the edges of the screen. The accuracy seems to degrade over time as more apps get opened. They are both running iOS 6.1.4. When the accuracy degrade gets too objectionable, powering down the phone (press and hold the top right side button until the red slider appears) seems to reset the accuracy once the phone is powered back up.

I wonder if powering down and back up would help accuracy in iOS 7?

I can vouch for this as well experiencing this first hand using my brother's iPhone 5s and comparing it to my LG Spectrum 2, Droid RAZR M, HTC Rezound and Incredible.

What got me into comparing it was some missteps while using his iPhone. At first I thought it was due to a smudgy screen. Then I went looking for a calibrator. I'm not sure if it's due to iOS7 or just the display tech in general. It's nothing drastic but kinda noticeable. My brother on the other hand had the iPhone freeze or become unresponsive when dialing a number.

How am I a troll? Is it because I said something you don't agree with? Against most users on the site, I'm one of the few who are unbiased and tell it like it is. Real world scenarios are my proof. You have the right not to believe it, that's fine, but hey I'm throwing my experiences out there.

I believe you now (but you do have trolling tendencies). I've never heard of it and never experienced it myself. Real world problems usually show up on the internet in the form of reviews and complaints, and more often with Apple too. I've just never seen a single one until today. I have no problem being proven wrong and learning something new. I'm not as obnoxiously stubborn as you :)

Everyone trolls from time to time. It makes everything a little more interesting don't you think? I wouldn't say stubborn, just a person who loves to have discussions and debates. :)

I understand where you're coming from, it's the type of issue that, as an iPhone user, you don't expect, to the point where, when it occur, you think you missed your spot, try a couple more times before succeeding, and kinda forget about it right after... until it happens again.

The fact that I never read about it anywhere also led me to think that I was placing my finger at the wrong place. That's why I'm kinda glad to see this article, it answers some of the doubts I had...

Still, iPhones are great devices which I would easily recommend, but they have to fix this...

This x100.

I'll admit, my S3 isn't perfect either, as I've encountered this problem probably three times in the past year.

i loved my att sIII but that keyboard sucked. I had more issues with the key board on it then i did with my iphone 4s.

For my RAZR M I ended up going to Hacker's Keyboard and Google Keyboard because of slightly better action and customizations. Luckily my Spectrum 2 and Rezound do really well with their stock keyboards.

No phone is really perfect with their touchscreens. Hopefully it's a software fix and not a hardware fault.

Sometimes it gets compounded when you add a screen protector.

When i had my iPhone 5 i went from an android phone and was typing on the keyboard and was just missing the letters on the edges i thought my handset was faulty but obviously not, you get used to it and it never became a problem again but the problem is there its a bit strange. Going to my Z1 now i am having trouble typing because im used to tapping the keys off centre like i did on my iPhone.

I'm not saying I never troll, as everyone does once in awhile. I do love Samsung, and have since 2002 so that's not going to change. I'll call something out regardless of said OEM or person. I'm one of the few users on this site that isn't biased and is open to anything.

You did good. +1 for you. ;)

I haven't had any accuracy issues on my ip5, and have never heard any ip5 user complain about touch accuracy. This is news to me, and I work with smartphones all day (both as sales and as a repairman).

Still touch phones can't beat keypad phones. Keypad phones are very accurate and responsive.

I'm actually faster with swipe now. Almost as fast on swipe as I am on a full sized keyboard. I was one of those screaming for a slide out keyboard phone too. But, I was wrong. I'm a believer now.

I type two or three times faster on a touch screen device than I do with a phone with a physical keyboard (LG enV Touch - best keyboard I've ever used on a phone). An added bonus is auto correct. I type really really fast on my phone, and it saves me so much time and is accurate about 95% of the time. Gesture typing on Google Keyboard and Swift Key is perfect.
