It looks like Apple may be slacking when it comes to touchscreen accuracy. A new study from OptoFidelity put the new iPhone 5s and iPhone 5c up against the Galaxy S III in an automated test, and the outdated Samsung handset pretty much destroyed its competition.

The study used a robotic finger and some specialized testing software to test each device’s input response across the entire display. The image above shows the results, with green signifying a measurement within one millimeter of accuracy, while red shows any area where the touchscreen was over one millimeter off.

The results demonstrate that while the iPhones’ accuracy is focused around the area where the keypad generally appears, the Galaxy S III offers solid accuracy across the entire device. For the most part, this isn’t a really issue, but the report notes that the discrepancy makes it much easier to write with the Samsung device, while the new iPhones are more prone to typos. Also, we can’t figure out why a Galaxy S4 wasn’t tested instead.
