Camera is used by another app on Android: 7 ways to solve the problem

Are you trying to take a selfie or start a video call, but instead of a picture from the camera you see an annoying message: “The camera is being used by another application”? This error is one of the most common on Androiddevices, and it can even occur on flagship models like Samsung Galaxy S23 or Google Pixel 7. The reason lies in the architecture of the operating system: Android allows only one process to simultaneously manage the camera hardware modules, and if the application “forgot” to release the resource or froze, other apps will not be able to use it.

In 80% of cases, the problem is caused by background processes of instant messengers (for example WhatsApp or Telegram), applications for video calls (Zoom, Google Meet), or even system services like com.android.camera. Less commonly, viruses, incorrect updates, or hardware failures are to blame. In this article we will look all working methods from basic to advanced, including commands ADB and hidden developer settings. Let's start with the simplest solutions that do not require technical knowledge.

1. Force stopping the conflicting application

The first and fastest way is to find and close the app that “blocked” the camera. Most often, these are applications that recently used the camera, but did not release it correctly.

How to do this:

• 📱 Open Settings → Applications (on some firmware - Settings → All applications).
• 🔍 In the list, find applications that could use the camera: Instagram, TikTok, Skype, Facebook, Snapchat or system Camera.
• 🛑 Click on the application → Force stop (or Stop).
• 🔄 Restart the camera or other application that generated the error.

If you don’t know which application is to blame, stop all suspicious ones by queue. On Xiaomi, Realme and some other firmware there is a separate section Autorun - check if background access to the camera is enabled for unnecessary apps.

2. Rebooting the device

It sounds trivial, but a reboot solves the problem in 30% of cases.When an application “freezes” with the camera captured, the operating system cannot always correctly release the resource without a full restart.

How to reboot correctly:

• 🔄 Soft reboot: hold down the power button → select Reboot (or Restart).
• 🔋 Hard reboot (if the device is frozen): press the power button + Volume down for 10-15 seconds until the screen goes blank.

After reboot, check the camera in Google Camera or another application. If the error remains, proceed to the following methods.

3. Clearing the cache and data of the Camera application

Sometimes the problem lies not in third-party apps, but in camera system application. Its cache or damaged data may block access to the module.

Instructions:

1. Open Settings → Applications.
2. Find the system application Camera (on Samsung can be called Camera or Secret Camera).
3. Click Storage → Clear cache.
4. If that doesn't help, click Clear data (⚠️ this will reset the camera settings!).

After cleaning restart the device. If you use Google Camera (GCam) or third-party modifications, remove and reinstall them - they may conflict with the system camera.

What to do if the “Clear data” button is inactive?

On some firmware (for example, MIUI or ColorOS) system applications are protected from changes. In this case, only resetting the settings (see section 6) or using ADB (section 7) will help.

4. Checking application permissions

Sometimes an error occurs. because incorrect permissions: The application is trying to access the camera, but the system is blocking it for an unknown reason. Or vice versa - several apps simultaneously request access.

How to check:

• 🔒 Open Settings → Privacy → Manager permissions → Camera (path may vary).
• 📋 View the list of applications with access to the camera. Turn off permission for suspicious apps (especially if there are a lot of them).
• 🔄 Restart the camera.

There is a function Android 12+ there is a function Precise location access for the camera - check if it is enabled for unnecessary applications. Also pay attention to applications with access to the microphone —they can indirectly block the camera (for example, Shazam or Google Assistant).

5. Safe mode and virus scan

If the error appears even after rebooting and clearing the cache, it may be to blame malware or a conflict with running services. To check this, boot the device into safe mode - it disables all third-party applications.

How to start safe mode:

• 🔄 Press the power button → long tap on Turn off (or Turn off power).
• 🛡️ Select Safe Mode (on some devices you need to hold Disable until the request appears).
• 📸 Check the camera operation in safe mode. If the error disappears, one of the installed applications is to blame.

If the camera works, uninstall recently installed apps or scan your device for viruses using Malwarebytes or Dr.Web Light. Pay special attention to applications with suspicious permissions (access to Accessibility, Window overlay or Administrator devices).

⚠️ Attention: In safe mode, all widgets and background processes are disabled. If, after exiting it, the camera does not work again, the problem may be in the system software - consider resetting the settings (section 6).

6. Resetting the settings to factory settings.

This last resortif none of the above helped, resetting will delete all data from the device, including applications, accounts and settings, but will return the camera to working condition.

How to reset:

1. 📱 Open Settings → System → Reset settings (to Samsung: Device maintenance → Reset).
2. 🔄 Select Reset all settings or Delete all data.
3. 🔐 Enter your PIN/password if required.
4. ⏳ Wait for it to complete (takes 5–15 minutes).

After the reset, the camera should work. If the error remains, there is a problem hardware (the camera module or cable is damaged). In this case, contact the service center.

Method	Execution time	Efficiency	Risks
Forced application stop	1–2 minutes	⭐⭐⭐⭐ (high)	No
Reboot	1 minute	⭐⭐⭐ (medium)	No
Clear camera cache	2–3 minutes	⭐⭐⭐⭐ (high)	Reset camera settings
Reset settings	10–15 minutes	⭐⭐⭐⭐⭐ (maximum)	Data loss
ADB commands	5–10 minutes	⭐⭐⭐⭐ (high)	Requires a PC and knowledge

7. Advanced methods: ADB and developer settings

If you are an advanced user, you can try release the camera via ADB or change the developer settings. These methods are suitable for Android 10+ and require connection to a computer.

Method 1: Release the camera via ADB

1. 🖥️ Install ADB on PC (download Platform Tools from the site Google).
2. 📱 Turn on Debug by USB on your phone (Settings → About phone → Build number → tap 7 times → return to Settings → System → For developers).
3. 🔌 Connect your phone to the PC and run the commands:

   adb shell
   su
   dumpsys media.camera | grep "Client"

   This will show which application is using the camera Then. run:

   kill [application_PID]

   (replace [application_PID] with the real identifier from the command output).

Method 2: Disabling background processes

• 🛠️ Enable Developer mode (as in point 2).
• 🔧 Find option Do not save actions (or Limit background processes) and set the limit to 1-2 processes.
• 🔄 Reboot the device.

⚠️ Attention: Commands ADB and changes in developer settings can lead to unstable system operation. Do not use them if you are not sure of your actions. On some firmware (for example, Huawei EMUI), these methods may be blocked.

FAQ: Frequently asked questions about camera conflicts on Android

Can an antivirus block access to the camera?

Yes, some antiviruses (for example, Avast or Kaspersky) can block access to the camera for “suspicious” applications. Check your antivirus settings in the Privacy protection or Permissionssection. Also temporarily disable protection and check if the error disappears.

Why is the camera busy even after closing all applications?

This may be due to:

• 👻 Background services (for example, Google Lens or ARCore), which are not displayed in the list of running applications.
• 🔄 System failures in mediaserver (responsible for the operation of the camera and microphone).
• 📱 Firmware with bugs (especially important for custom ROMs like LineageOS).

Solution: try the method with ADB (section 7) or resetting the settings.

How to check if the camera works at the hardware level?

To exclude software errors:

1. Boot the device into recovery mode (Power + Volume Up).
2. Some firmware (for example, Samsung or Xiaomi) have a built-in hardware test. Find the item Diagnostics or Hardware Test.
3. If the camera does not work even in test mode, there is a hardware problem.

Is it possible to use the camera on two applications at the same time?

On most devices - no. Android by default it blocks simultaneous access to camera due to driver and security limitations. However, some manufacturers (for example, Samsung v One UI 5+) add support Multi-Camera APIthat allows you to use the camera in two applications (for example, Instagram + TikTok). Check your camera settings for the option Multitasking or Dual window.

Why did the camera stop working after updating Android?

Updates often break compatibility with older camera drivers. This is especially true for:

• 📱 Devices with MediaTekprocessors (for example, Redmi Note or Realme).
• 🔧 Smartphones with custom firmware (Custom ROM).
• 📸 Camera modules from Sony IMX (popular in 2018–2022 flagships).

Solution: roll back to the previous firmware version (if possible) or wait for a patch from the manufacturer. On the forums XDA-Developers fixed drivers for popular ones are often posted. models.
