攝影機及錄音，無法使用！……1.被其他程序使用。 2.因“安全性原則”。”

An error message on the Samsung Galaxy A50 says that security precautions prevent the camera and recording from being used. This typically indicates that the camera or microphone is being used by another app, or that access is being blocked by security settings or permissions. Close apps that use the camera or microphone, verify app permissions, and look for security or privacy settings to resolve this. Update the software, restart in Safe Mode, and empty the cache of the camera app. If none of these fixes resolve the problem, you might need to factory reset the phone or have Samsung service check it for suspected hardware problems.
