Why Is There a Purple Light on My iPhone?: 1 Minute to Understand Your Device's Notifications

If you've noticed a purple light on your iPhone, you're certainly not alone. Many users observe this mysterious glow, usually manifesting as a faint, pulsing or static dot near the top of the phone, typically visible in low light or when using the front-facing camera. This “purple light” isn't a flaw—it's actually a feature tied to your iPhone's infrared sensors, which play crucial roles in Face ID and other security or proximity functions. The human eye can barely see infrared light, but under certain conditions, especially when viewed through another camera or in dim environments, this otherwise invisible light may appear purple or reddish on your screen.

From a functional perspective, this indicates your iPhone's sensors are active and performing tasks such as facial recognition, eye-tracking for accessibility features, or proximity detection (for example, turning off the screen during phone calls). It's a normal part of the device’s operation and not a cause for concern. However, if the appearance of the purple light is accompanied by device malfunctions, screen flickering, or if it persists while your phone is idle and should not be using Face ID, then a hardware issue or software misconfiguration might be present, and you should consider reaching out to Apple support.
