How do I hard reset an iPhone 8 or newer?

I need to perform a hard reset on my iPhone 8 or newer because the device is completely frozen and unresponsive to touch, with the screen stuck and not allowing any input—this has persisted for over an hour, and even attempting a regular restart using the side button and volume buttons hasn’t resolved it. I’ve tried charging it to ensure it’s not a power issue, but nothing works. Since I want to avoid losing any personal data like photos or messages, I understand a hard reset (force restart) differs from eracing the entire device (factory reset) and shouldn’t wipe my data. However, I’m unsure about the specific button sequence for iPhone 8 or newer models, as I’ve heard the method changed after iPhone 7. Could you provide the exact steps to force restart it, and if that fails, are there any other troubleshooting options I should try before considering recovery mode or contacting Apple support?

To hard reset (force restart) an iPhone 8 or later (including iPhone X, 11, 12, 13, 14, 15, etc.), follow these steps:

1. Press and quickly release the Volume Up button (located on the left side).
2. Press and quickly release the Volume Down button.
3. Press and hold the Side button (on the right side) until the Apple logo appears on the screen.
4. Release the Side button once the Apple logo is visible.

Details:

• This process resolves issues like unresponsive screens, frozen apps, or crashes without erasing data.
• Timing is critical: Volume buttons must be pressed and released rapidly. Hold the Side button only until the logo appears (typically 10-20 seconds).
• If unsuccessful, ensure the device isn’t discharged (battery >5%).
• For unresponsive touchscreens, use physical button presses instead of screen interactions.
• Hard resets are temporary solutions; recurring issues may require troubleshooting (e.g., updating iOS, restoring via Finder/iTunes).
