To reboot your iPhone, use the buttons for a quick restart (Volume Up, Volume Down, then hold Side Button for newer models) or go to Settings > General > Shut Down. A force restart (Volume Up/Down quick press, then hold Side Button until Apple logo) is best for frozen screens and doesn't delete data, while the standard restart involves sliding to power off and back on.
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.
To force a hard reboot (or power reset) when a device is frozen, press and hold its physical power button for about 10-20 seconds until it shuts down completely, then press it again to restart; for phones, specific button combos like Volume Down + Power (Android) or Volume Up, Volume Down, then Power (iPhone) are used, but always try the power button first, as this process can cause you to lose unsaved work.
If iPhone isn't responding, and you can't turn it off then on, try forcing it to restart.
Open security screen: Press Ctrl + Alt + Del. Force restart: Hold Ctrl while pressing the power button icon.
iPhones generally do not last that long even when kept in mint condition. You are in no danger of damaging your device through a reset.
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.
Press and quickly release the volume down button. Press and hold the side button. When the Apple logo appears, release the side button.
The combination of keys used for restarting the computer is Ctrl+Alt+Delete.

A computer reset is different from a reboot or restart. Whereas a computer reboot and restart power down the operating system and restart it, a computer reset is when you take the machine back to its original state with the reinstallation of the operating system.
