The Cause of an iPhone Screen That’s Turned Black and White
The most common cause of an iPhone screen that turns black and white is changing the iPhone’s software settings. The iPhone supports several ways to make the display black and white in its accessibility settings. These are helpful for people who have trouble seeing (or can’t see) all or any color or have difficulty with low contrast images.
This article will help you fix an iPhone screen that turns black and white. This issue is different from the iPhone’s white screen of death, an issue that will turn the entire screen white.
How to Fix an iPhone Screen That’s Turned Black and White
The cause of an iPhone screen turning black and white is likely a software issue, so most solutions involve changing settings in the iPhone’s settings app. The steps below apply to all iPhone models with a current version of iOS.
Press your iPhone’s Lock Screen button three times in rapid succession. If you have an iPhone with a Home button, tap it three times instead. This action activates the iPhone’s accessibility shortcut if you set it up. You can configure this shortcut to switch an iPhone into grayscale mode, which may cause your issue. Open your iPhone’s Display & Text Size settings to turn off the color filter if it’s on. Color Filters are an iPhone accessibility feature. The Grayscale filter turns the iPhone screen black and white, making it a common cause of this issue. Open your iPhone’s Zoom settings to turn off Zoom if it’s on. The iPhone’s Zoom setting has a Grayscale color filter located under Zoom Filter in the Zoom settings menu. This filter will turn the iPhone screen black and white when the Zoom feature is on. In this case, Zoom doesn’t refer to the video service called Zoom. Zoom is a function inside iOS’s accessibility settings: Settings > Accessibility > Zoom. Reset All Settings on your iPhone to return all settings to default. It will turn off any iOS feature on your iPhone responsible for turning your iPhone screen black and white. However, it will also reset all other settings, so this is the last resort. While this resets all settings on your iPhone, it does not delete your content.
