Likely causes
- CommonAnother app or process still holding the camera hardwareIf an app crashed while using the camera, it can leave the hardware locked until restart.
- CommonSoftware bug or corrupted camera app dataA glitch in the camera app itself can trigger this generic error.
- PossibleLow storage or memory preventing camera initializationInsufficient resources can prevent the camera system from starting properly.
- PossibleHardware fault with the camera moduleIf the error persists across restarts and all apps, the camera hardware itself may have failed.
What to do
- Force close all apps that might be using the camera, then restart the phone.
- Free up storage space.
- Clear the camera app's cache and data through settings, if available.
- Test a different camera app to see if the error is specific to the default one.
- Update the operating system.
- If the error appears in every app after a restart, treat it as a likely hardware issue.
