iOS 27.3 beta brings the iPhone Duo's new StandBy faces to iPhone 11 and newer, MacRumors reports
Apple's first iOS 27.3 developer beta carries a set of StandBy upgrades that debuted on the iPhone Duo and now extend to every iPhone that can run the update, according to Apple's release notes as cited by MacRumors.
StandBy is the full-screen display mode that appears when an iPhone is charging while on its side. On the iPhone Duo it also works when the device is folded, even without a charger. With iOS 27.3, several of the options built for that device are being opened up to iPhone 11 and newer.
