The iOS 16.0.3 update improves security.

The newest update arrives four weeks after iOS 16 was released in mid-September.

The most recent version fixes problems on select iPhone 14 models, 

such as delayed or undelivered incoming calls and alerts, as well as low microphone loudness during CarPlay phone conversations.

It also addresses camera difficulties that some iPhone 14 models have had,

such as poor launch speeds or unexpected switching between camera settings.

The update also includes non-specific updates for iPhone 14 devices.

One modification fixes a problem in which a malformed email might crash the Mail app.

– Here's how iPhone users can download the update.

– Open Settings. – Tap General. – Tap Software Update. – Tap Download and Install.
