Have you seen the viral TikToks claiming your iPhone secretly snaps a picture of you every few seconds? Those shot with infrared cameras — showing flashes from the iPhone’s TrueDepth system and fueling speculation about surveillance and unwanted tracking. Are Apple devices actually quietly watching their users, or is it just a misunderstanding of how Face ID works? Let’s see.
Why are people worried about Face ID?
The wave of concern started when a TikTok video showed an iPhone emitting invisible infrared flashes. When captured with a special camera, these pulses appeared every few seconds, leading some viewers to ask: Why does my iPhone take pictures every 5 seconds?
Comments on the video were filled with suspicion. Some feared it meant their phone was constantly photographing them, while others compared it to surveillance technologies. Similar questions began trending, such as: Does your phone take a picture every 5 seconds? and Do iPhones take pictures of you without consent?
While the reaction is understandable, the explanation lies not in secret surveillance, but in how Apple’s Face ID and TrueDepth camera system function.
How Apple’s Face ID and TrueDepth camera work
The iPhone’s TrueDepth system is made up of three components:
- Infrared camera — detects invisible light and reads facial patterns;
- Flood illuminator — helps the system see in the dark;
- Dot projector — casts over 30,000 tiny infrared dots to map a user’s face in 3D.
When you enable Face ID, your iPhone stores a mathematical representation of your face. Each time you try to unlock your device, the system projects those dots, measures depth, and compares the scan with the saved model.
These infrared pulses are not photos but depth scans. Importantly, these scans only happen when the device expects interaction, such as when you pick it up or glance at it. And because Face ID measures depth, a flat photo of your face cannot unlock your device. The technology ensures only a real, three-dimensional face can be recognized.
Why Face ID improves your phone experience
Beyond unlocking your device, Face ID enhances everyday use. It grants you:
- Quick access: you can unlock your iPhone in a secure and seamless way;
- Attention-aware features: your screen dims when you’re not looking, and notification volume lowers when you’re facing the screen, which helps save battery.
In other words, Face ID isn’t just about security. It’s also designed to make your iPhone more intuitive, responsive, and power-efficient.
Is your facial data safe?
So, if you’re not very familiar with how iPhone’s Face ID works behind the scenes, the worry of it constantly scanning your face is understandable. But a more important question here is, where does all that data go?
According to Apple, your facial model never leaves the device. It’s stored inside the Secure Enclave, a dedicated part of the iPhone’s hardware isolated from the operating system and internet-connected apps. This design reduces the risk of remote hacking or data leaks.
However, if you want to add an extra layer of security and privacy when surfing the web or using apps, a VPN (Virtual Private Network) such as Surfshark can help. Besides masking your IP (Internet Protocol) address, it encrypts your online traffic, which minimizes tracking and complements the protections already built into iOS.
How to turn off Face ID or manage its settings
If you’re still uneasy about infrared scanning, you can limit or disable Face ID:
- Open Settings > Face ID & Passcode.
- Enter your passcode if prompted.
- Toggle off:
- Require Attention for Face ID;
- Attention-Aware Features.
You can also disable Face ID entirely and use a passcode instead. This stops the face scanning.
Final thoughts: Should you worry about Face ID?
So, your iPhone isn’t secretly filling your photo library with hidden selfies. It’s the TrueDepth system scanning your face with infrared light to enable Face ID and related features. While this technology is primarily about security and convenience, your privacy concerns are valid, and Apple gives you the choice to disable these features.
However, understanding how the system works helps separate fact from fear, and you can decide what balance of security and privacy works best for you.
FAQ
Is my iPhone secretly taking pictures?
No, your iPhone doesn’t secretly take photos. Apps must ask for Camera permission, and when any app uses your camera, you’ll see the green indicator dot at the top of the screen.
System features like Face ID use the TrueDepth/infrared camera for authentication and attention checks, but they don’t save images to your Photos library or send them off-device.
How do I stop my phone from automatically taking screenshots?
iPhones don’t automatically take screenshots, and most “auto” screenshots are accidental.
There’s no system setting to fully disable screenshots, but you can try:
• Removing Back Tap screenshot: Settings > Accessibility > Touch > Back Tap > set both Double Tap and Triple Tap to None;
• Checking AssistiveTouch custom actions: Settings > Accessibility > Touch > AssistiveTouch > Custom Actions > remove Screenshot if assigned;
• Preventing Apple Watch screenshots: Watch app > General > turn off Enable Screenshots;
• Avoiding pressing Side + Volume Up together when picking up the phone — a case with raised buttons can help reduce accidental presses.
Why are random photos appearing on my iPhone?
Some common reasons for random photos appearing on your iPhone include:
• iCloud Photos syncing from your other devices (iPad/Mac/another iPhone);
• You’re viewing/contributing to iCloud Shared Photo Library;
• You’re subscribed to other people’s shared albums;
• Your Apple Watch is taking screenshots;
• Messaging/third-party apps are auto-saving photos;
• People are AirDropping photos to your device.
Can I disable Face ID completely?
Yes. To disable Face ID completely, go to Settings > Face ID & Passcode > enter your passcode > under Use Fade ID For, toggle off all settings.
Alternatively, you can reset your Face ID to remove your face data: Settings > Face ID & Passcode > enter your passcode > Reset Face ID.
