Today, Apple began rolling out iOS 14.4 and iPadOS 14.4 to supported iPhone, iPad, and iPod Touch devices. The company also pushed watchOS 7.3 to Apple Watches and tvOS 14.4 to Apple TVs.
iOS 14.4/iPadOS 14.4 is a somewhat small feature update. New additions in the release notes include the ability to read smaller QR codes with the iPhone cameras, notifications to tell users "when the camera of your iPhone is unable to be verified as a new, genuine Apple camera," and a number of bug fixes.
