Apple’s (NASDAQ:AAPL) iPhone 5S and iPhone 5C performed worse than Samsung’s (SSNLF.PK) Galaxy S3 in a recent touch accuracy test conducted by Finnish technology testing company OptoFidelity. The company used an automated Touch Panel Performance Tester device to measure the touch panel accuracy on Apple’s two new iPhones, as well as Samsung’s older-generation Galaxy S3.
The device tested the touch panel accuracy on each device by tapping across the screen and comparing the actual touch position with the reported coordinates. As noted by OptoFidelity, the test placed a pass/fail limit of +/- 1 millimeter for each touch position. In the graphic seen above, a green point indicates a pass and a red point indicates a fail.
In the words of OptoFidelity, the test results were “highly surprising.” The test revealed that Apple’s iPhones had “extremely bad” touch accuracy around the edges of the screen. The test also showed that the iPhone’s touch performance is better towards the bottom of the screen.
