Apple has released another update for iOS 13 on Monday — the third in the space of a week, bringing it to version 13.1.2.

Just like the last update, this one is mostly about bug fixing and does not bring any significant new features.

The most important fix is for a bug in which the phone's camera didn't work. Others include fixing a progress bar bug in iCloud Backup, an issue in which the flashlight sometimes did not activate, a bug that could result in a loss of display calibration data, an issue in which shortcuts could not be run from HomePod, and a Bluetooth disconnection bug in "certain vehicles."

To install the update on your iPhone, go to Settings - General - Software Update - Download and Install.

Apple's iPadOS was also updated to 13.1.2 on Monday, and watchOS was updated to version 6.0.1.

Apple typically does some quick bug-squashing after a major new release, but this series of updates was more rapid than usual. Apple's iOS 13 was released on Sept. 19, to coincide with iPhone 11 coming to stores, but Apple quickly followed with 13.1 on Sept. 24, and then 13.1.1 on Sept. 27.

The updates come after numerous reports on a variety of bugs in iOS 13 — but at least Apple's wasting no time in addressing them.
