iOS 7 beta 4 refines design of call buttons

The latest beta for iOS 7 highlights several subtle but notable changes since the third beta.

Apple continues to refine certain elements in iOS 7 as seen in the fourth beta released on Monday.

The phone buttons that appear in response to an incoming call are now less text-heavy, as noted by AppleInsider. The buttons for "remind me later" and "respond with text" have been renamed to simply "remind me" and "message" with icons to represent their roles.

All the call buttons, including those for decline and answer, also have received a small aesthetic change. Their transparency has been reduced so they now appear almost opaque. Apple received a decidedly mixed reaction to the style changes that surfaced in the first iOS 7 beta. It now appears that each new beta is slightly dialing back some of the severity of those changes.

Biometric scanner code discovered in the latest beta for iOS 7 also points to fingerprint recognition, a feature that could very well pop up in the iPhone either this year or next.

Updated at 9:15 a.m. PT: to correct assertions that the iOS 7 beta 4 includes changes to Spotlight search. Those changes were present in prior betas.
