How to quickly press the power button 3 times to turn iPhone to black and white?
We know that on the iPhone you can dim or brighten the screen to your liking, or use Dark Mode, True Tone, and Night Shift to automatically adjust. But it turns out that in addition to these different brightness and vividness, we can turn the screen to black and white by quickly pressing the power button 3 times!
1. Go to “Settings” >>> “Accessibility” >>> “Display and Text Size” >>> “Color Filters” and open it and select “Grayscale”.
2. Go back to “Accessibility” and scroll down to select “Accessibility Hot Key”, which provides the action you want to activate after quickly pressing the power button 3 times, so here we select the “Color Filter” option .
After setting these two steps, no matter which screen you are on, quickly press the power button 3 times to turn the screen to black and white.If you want to switch back to color, you can also press the power button 3 times more. However, it should be noted that although it appears to be a black and white screen, if it is a screenshot, it will still display as a color screen!
