To restart a frozen iPhone on iOS 15 without the power button, use the force restart method: quickly press and release the Volume Up button, then quickly press and release the Volume Down button, then press and hold the Side (power) button until the Apple logo appears, which forces a software reload without data loss.
Three-finger gestures on iPhone primarily activate accessibility features like VoiceOver (for screen reading and navigation) and Zoom (magnification), allowing scrolling, zooming, and text manipulation (copy/paste/undo) with specific taps and drags, though some text actions work without VoiceOver enabled for quick editing. Common gestures include three-finger double-tap to toggle VoiceOver speech, triple-tap for the screen curtain, and pinching/spreading with three fingers for copy/paste actions, notes this YouTube video.
To force restart your phone, press and hold the correct button combination for your device (usually Power + Volume Down for Android, or a sequence of Volume Up, Volume Down, then Hold Side Button for iPhone) for several seconds until the device vibrates and the logo appears, bypassing a frozen screen without deleting data.
The risk of system corruption is significant when you forcefully restart. The operating system (OS) manages numerous processes and data exchanges; interrupting these can lead to corrupted system files.
