Apple’s iPhone 5s has only been out for a few weeks now, and already the device is suffering from issues with its accelerometer. The iPhone 5s accelerometer problems center around incorrect level and compass measurements, which may be worrisome if the part is used for other applications. Apple switched suppliers with the iPhone 5s, and is now receiving the part from Bosch Sensortech. The same accelerometer part in the iPhone 5 was supplied by STMicroelectronics, which doesn’t seem to be having the same issues.
According to a report from Gizmodo, the issue may have occurred because Apple switched suppliers, and the original design may have had a defect. In the report, a GIF shows Real Racing being played, and the vehicle driving off to the side as the iPhone sits level on the table. RealityCap—a company that works with sensor-based real-time 3D location software for iOS—has figured out a solution to the issue, though it seems very annoying for developers.
RealityCap’s CEO, Eagle Jones, explained that the issue in the iPhone 5s is occurring because accelerometer accuracy relies on variance as well as how consistent the readings are, and that it can be fixed if developers adjust the code inside of their applications. This will allow for the software to even out the incorrect measurements.
Apple has yet to comment, though it will likely address the issue in a future software update. Even so, this means that Apple will have to add in an incorrect measurement in order to ensure it balances out the faulty accelerometer.
