That tiny green dot in the corner of your phone’s screen isn’t an error or a random notification — it’s actually your phone trying to tell you something important about your privacy. Both iPhone and Android devices now use this indicator to let you know when certain hardware is being accessed. Most of the time, it is completely harmless. But sometimes it pays to be careful.
1. It means an app is using your camera

According to Apple Support, a green indicator on the iPhone means that either the camera alone or the camera and microphone together is being used by an app. This feature was introduced with iOS 14 as a privacy measure, giving users real-time awareness of when their device’s sensors are active. The dot appears in the upper right corner of the screen, next to the battery and signal icons.
On Android devices running version 12 or later, the green dot serves a similar purpose. Lights up whenever an app accesses your camera or microphone. The indicator works automatically in the background without requiring any user configuration – it is built into the operating system as a standard privacy feature.
2. It is different from the orange dot on the iPhone

iPhone users actually have two privacy indicators to watch. The green dot signals access to the camera, while an orange dot means an app is only using the microphone. If you are in a video call where both are active, you will only see the green dot as it covers both scenarios.
Android phones handle this differently. According to security experts, Android devices only use the green dot indicator for both camera and microphone access instead of separating them into two colors. When an app first accesses your sensors, you’ll briefly see a camera or microphone icon before it changes to the simple green dot.
3. You can find out which app is responsible

Privacy experts recommend making it a habit to immediately check your Control Center whenever you see the green or orange dot appear on your iPhone. Simply swipe down from the top right corner of the screen and you’ll see the name of the app currently using the camera or microphone displayed at the top. For older iPhones with a home button, swipe up from the bottom.
On Android, the process is similar. Swipe down from the top of the screen when you see the green dot and you’ll see either a camera or microphone icon. Tap it to reveal the app accessing your hardware. This identification system allows you to capture potentially unwanted access in real time.
4. It can occur for absolutely normal reasons

The appearance of the green dot does not automatically mean that something sinister is happening. Appears during expected activities such as taking photos, recording videos, making video calls, or using FaceTime. It also lights up during less obvious but still legitimate uses, such as scanning a QR code or interacting with Google Assistant.
Many people see the dot and immediately worry, but the most common explanation is simply that an app you’ve been using recently is still running in the background. You may have quit the camera app or video chat without closing them completely.
5. Background apps are often the culprit

Security researchers note that people regularly switch between apps without closing them when they’re done, meaning your camera or microphone could be accessed by an app you didn’t know was still running. A video conferencing app might still be active after you thought you ended the call, or a social networking app might be accessing your camera even when you’re not actively taking photos.
If you see the dot appearing unexpectedly, close all open applications and see if it disappears. On iPhone, swipe up from the bottom and pause to see your open apps, then swipe them away. On Android, use the recent apps button to close running apps.
6. It could signal a privacy issue

While most occurrences of green dots are harmless, there is a more worrying possibility. According to cybersecurity experts, there could be a spyware application running in the background, accessing your microphone and camera to spy on you and steal your data. If the point appears when you’re not actively using any apps that should have access to the camera, it’s worth investigating.
Signs of a genuine problem include the dot constantly appearing even when no apps are open, unknown app names appearing when you check Control Center, or the indicator flashing repeatedly throughout the day for no apparent reason.
7. You should check app permissions regularly

According to security guidelines, you should be concerned if you see the green privacy indicator showing all the time, even when you’re not using any app in particular — that means a certain app has continuous access to your microphone, camera, or both, and it’s likely a malicious app that could be spying on you.
To check which apps have access to the camera on your iPhone, go to Settings, then Privacy & Security, then Camera. On Android, navigate to Settings, then Privacy, then Permission Manager, then Camera. From these menus, you can revoke access for any app that doesn’t need it.
8. Some apps ask for more access than they need

Not all apps that ask for camera or microphone permission need it. A weather app has no legitimate reason to access your camera. A computer should not need a microphone. If you notice apps with unnecessary permissions, it’s worth asking why and revoking that access.
Security experts recommend auditing your permissions periodically. Look at every app that has access to the camera or microphone and ask yourself if it really needs that capability to work. If the answer is no, disable the permission.
9. The indicator cannot be turned off

Unlike most phone features, you can’t turn off the green privacy indicator. Both Apple and Google created these indicators as permanent security features, specifically because users need to be aware of when their sensors are active. The dot will appear every time an app accesses your camera, regardless of your settings.
This is by design. If users could turn off the indicator, it would defeat the purpose – malicious apps could access your camera without any visual warning. The feature’s persistence is part of what makes it useful as a security tool.
10. Android 12 added quick toggles for extra control

Android 12 and later gives users the ability to completely turn off camera and microphone access for all apps at once. In the Quick Settings panel, you’ll find toggles labeled “Camera Access” and “Microphone Access” that allow you to disable these features system-wide with a single tap.
This is useful when you want total privacy and don’t want any app or service to access your sensors. It’s more comprehensive than managing individual app permissions and provides a quick way to make sure nothing can activate your hardware without you explicitly allowing it again.
11. Laptops have had this feature for years

The green dot on phones reflects a feature that laptops have included for much longer. Most laptop webcams have a physical LED light that lights up whenever the camera is active. This hardware-based indicator helped users know when video calls are active or when an app might be accessing the webcam unexpectedly.
Apple explicitly modeled the iPhone’s green dot after the MacBook’s webcam indicator, bringing the same transparency to mobile devices. The digital version serves the same purpose as the physical LED – it alerts you when the recording hardware is in use.
12. A factory reset is the last option

If you’ve checked permissions, closed all apps, and still see the green dot appearing inexplicably, security professionals suggest a factory reset as a last resort. This wipes everything off your device and removes any potentially malicious software that may have embedded itself deep into your system.
Before taking this step, please back up your important data. After the reset, only reinstall the apps you trust and need. This approach is drastic but effective when you truly suspect that your device has been compromised and other troubleshooting steps have not resolved the issue.
