The update to iOS 7.0.3 comes with a number of bug fixes, but perhaps the most notable tweak corrects issues with the iPhone 5S’ accelerometer, gyroscope, and compass.

iOS 7.0.3 update fixes iPhone 5S’ broken motion sensors

While not quite the controversy that was antennagate, sensorgate (or gyrogate in some circles) saw the iPhone 5S ship with poorly calibrated motion sensors. This led to accelerometer, gyroscope, and compass data that was off by as many as six degrees. The result not only meant a busted stock compass/level app but also made for less-than-precise controls for games taking advantage of the iPhone’s motion sensors.

The iOS 7.0.3 update (which somehow snuck by us during the hullabaloo that was the new iPad launch event) manages to offer a software fix for what was determined to be a hardware issue, most likely by providing code to re-bias sensor readings on the fly. For the iPhone 5S (and 5C), Apple switched suppliers for its motion sensor components, components offering drastically different readings than their iPhone 5 counterparts.

While the initial diagnosis was that the problem would have been best handled by calibrating phones before they even left the factory, evidence suggest that the fix in iOS 7.0.3 is equally effective. Readings now match those of the iPhone 5, more or less, and are within a smaller acceptable range of error.

Feel free to once again hang all the shelves you want using only your iPhone as a level. They shouldn’t be crooked anymore.
