iPhone 5S accelerometer issues fixed by iOS 7.03

The much reported accelerometer issues faced by the iPhone 5S since its launch have been completely fixed by Apple's iOS 7.03 update.

Around two weeks ago we first reported on the problem, when it was found that the new iPhone 5S's orientation sensors were not proving to be as accurate as the iPhone 5's.

Apple's own in-built spirit level app showed a consistent two to three degree discrepancy, as did the preloaded gyroscope app. Running a motion-sensitive game such as Real Racing 3 revealed the potential practical issues, with cars automatically steering left.

Then last week we reported on the possible source of these problems - a new sensor component. Apple had switched from a Bosch sensor to an STMicroelectronics equivalent, but the new part was out of whack on the bias front.

This week Apple launched an update to iOS 7 that fixed a number of bugs and snags, and also added whole new features. iOS 7.03 introduces iCloud Keychain support, which formulates, stores and syncs unique passwords across all of your Apple devices.

Perhaps most significantly of all, iOS 7.03 has been shown to have fixed those iPhone 5S (and iPhone 5C) accelerometer issues.

Following a tip off from a source within Apple, VentureBeat took its iPhone 5S for a post-update spin. It found that the previous three degree discrepancy had disappeared, as demonstrated through Apple's spirit level app.

In our initial report we asked the question, "is this the latest Apple gaffe following Antennagate and the Apple Maps debacle?" It would appear as though the answer, following this swift and seemingly comprehensive software fix, is no.

To me the biggest improvement in 7.0.3 is the fact that the "Reduce Motion" setting now also stops the annoying zoom effects when you start and also switch apps. You get a nice subtle fade effect now which is a massive improvement to me. Surprised this isn't getting more press! I suddenly don't hate iOS 7 anymore, though they haven't fixed the awful colour palette, but accept that is just a personal preference thing.

it they fix the Iphone 5C with update then they would mess up the iphone 5 because both run on the same 32-bit ios so they won't because there are more iphone 5 than the iphone 5C

Agree completely with the color palette! Dreadful! Super saturated, unlike Apple. Hope the next iOS improves the colors!

I understand 7.04 brought the issue back. My 5C is off on 7.04 (I didn't test with 7.03).
