Additional Changes

As MacRumors notes, the second beta of iOS 14.4 also introduces a new setting to let you specify a device type for third-party Bluetooth audio devices for more accurate Headphone Audio Level measurements in the Health app. For example, this would allow you to designate whether you’re using in-ear or over-ear headphones, or even a speaker or a car stereo system so that your iPhone can make a better determination whether you’re listening to potentially dangerous audio levels.

The latest betas of iOS 14.4 and watchOS 7.3 also continue to include the “Time to Walk” setting for workouts that was discovered earlier this month, although so far, it doesn’t look like that’s changed in any way in the second beta.

Apple is also continuing its battle against unauthorized repairs; new code found in the latest beta shows that Apple will now be flagging camera replacements that use “non-genuine” parts, in much the same way that it began doing for display replacements back in 2019, and battery replacements before that.

Since the display warning was purely informational and didn’t impact the usability of your iPhone in any way, it’s a safe assumption that this will also be the case with the camera warning, which will likely appear on your lock screen and within your Settings app for a short time just to make you’re aware of that fact. It’s also likely that Apple will eventually publish a support document reminding users of the importance of using authorized Apple service and repair providers.
