To take a screenshot on an iPhone 6 Plus, you can follow these steps:
1. Locate the power button (also known as the Sleep/Wake button) on the right side of your iPhone.
2. Locate the Home button on the front of your iPhone.
3. Press and hold the power button and the Home button simultaneously.
4. Release both buttons quickly after taking the screenshot.
The screen will flash white and you will hear a camera shutter sound if your phone is not on silent mode. The screenshot will be saved to your Photos app.
