According to a new study, the Samsung Galaxy S3 outperformed Apple’s latest handsets in terms of overall screen accuracy. Finland based tech test and measurement company OptoFidelity used its own Touch Panel Performance Tester to measure the iPhone 5C, iPhone 5S, and Samsung Galaxy S3. The device uses a robot to “touch” exact coordinates on a screen. It then measures the coordinates of the touch device to see how closely they matched.
In above picture you can see that charts of iPhones are covered in red, which means accuracy is off by over a millimeter. The green area represents that accuracy is within a millimeter. It is clear from the charts that ageing Galaxy S3 has much better accuracy than the latest iPhones which further leads to less typing errors.
“Because the touch accuracy is more even in Galaxy S3 than in iPhone 5S and iPhone 5C, you get a lot less typing errors, and letters which are close to the edge are working better,” OptoFidelity said in its report. “You can also test this by tapping letters on the edge and typing long text messages.”
So, iPhone touchscreens may be fast in terms of responsiveness but are they accurate? No.
