iOS 9 Update Renders Some Features Unusable In iPhone 6S

When Apple rolled out iOS 9 for mobile devices earlier this month, users complained about failed software updates, battery issues, lagging, and crashing problems. The iPhone maker soon unveiled the iOS 9.0.1 update, promising to fix several bugs. However, the latest version also comes with several issues, and Apple may now have to push out another update.

Apps using compass and gyroscope data affected

Apple Insider reports that the iOS 9.0.1 affects apps running on iPhone 6S that use the compass and gyroscope data. For instance, the stargazing app Sky Guide transforms your iPhone into an interactive map of the night sky. It uses the three-axis gyroscope, digital compass, and accelerometer to power the augmented reality function. But the interactive map drifts wildly on the iPhone 6S running iOS 9 as well as the iOS 9.0.1.

Sky Guide developer Fifth Star Labs told Apple Insider that the issue was limited to the iPhone 6S. Sky Guide’s ‘Compass’ feature on older iPhones worked flawlessly. Many other augmented reality apps relying on iPhone’s advanced sensor suite were also experiencing problems. But Apple Maps was working correctly. Fifth Star Labs said it was working to fix the issue.

Users experience many other issues with iOS 9.0.1

Users have also reported many other issues after downloading the iOS 9.0.1 update. Many were still unable to download the updates. Some users witnessed their call logs vanishing. Other iPhone users also complained about the new Search features behaving abnormally. According to Product Reviews, several users were facing WiFi issues after updating to the iOS 9.0.1.

Now Apple needs to push out iOS 9.0.2 to fix these issues. The iPhone 6S and 6S Plus teardowns by iFixit revealed that the new phones use Bosch Sensortec 3-axis accelerometer and InvenSense 6-axis gyroscope/accelerometer chip, the same found in last year’s iPhone 6. Though iPhone 6S Plus users also reported overheating issues with the new phone, it is likely related to the processor instead of iOS.
