According to one tech testing company, Apple Inc. (NASDAQ:AAPL) still has some improvements to make on the iPhone 5C and 5S in regards to the touch accuracy.

iPhone 5 Samsung Galaxy S3

Samsung Galaxy S3 vs iPhones

OptoFidelity, a Finnish-based company, used their Touch Panel Performance Tester on both new iPhones and the Samsung Galaxy S3. This device has a robot that “touches” precise screen coordinates, then measures the coordinates from the touch device to see how they matched.

The data for both phones had failure rates around the edges and the top displays. The Galaxy S3, however, was more accurate across the screen although the edges showed errors. When the company started testing the virtual keyboards on all devices, they discovered that Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930)’s phone had more accuracy. OptoFidelity added, “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. You can also test this by tapping letters on the edge and typing long text messages.”

Interestingly enough, the company didn’t explain why they used the Galaxy S3 in the study rather than the Galaxy S4.

iPhone 5S demand

In other iPhone 5S news, Apple Inc. (NASDAQ:AAPL)’s flagship phone will be even more difficult to find. Gene Munster (analyst from Piper Jaffray) recently reported that availability has dwindled to less than five percent. CNET added, “Following the launch of the 5S on September 20, the new model accounted for 27 percent of all iPhones in stock, Munster said. But that number plummeted as consumer demand shot up. When might the iPhone 5S become less scarce? Munster noted that the supply of the earlier iPhone 5 didn’t catch up with demand until early December last year. So, we could be looking at the same scenario for the 5S. Apple Inc. (NASDAQ:AAPL)’s online store currently shows an estimated ship date for the 5S of two to three weeks.”

Samsung Electronics Co., Ltd. (LON:BC94) (KRX:005930) and Apple Inc. (NASDAQ:AAPL) are still vying for the lead in the smartphone market.
