To hard reset your Samsung ST1000 camera, follow these steps: Reset Settings via Camera Menu: Open the camera app. Tap on the Settings icon (usually represented by a gear). Scroll down and select Reset settings. Confirm the reset by choosing Yes when prompted. Physical Reset (if needed): Locate the reset button on your camera (refer to the camera's manual for its exact location). Press and hold the button for at least 10 seconds until the camera restarts

This seems to be a known issue where the Samsung Music app starts randomly1. Here are a few steps you can try to resolve this issue: Check if an app you downloaded is causing the problem: Start the phone in Safe Mode. If the problem does not occur in this mode, then you need to find out what app this is and uninstall it. Wipe the cache partition of the phone from the recovery mode: This can often resolve issues with apps misbehaving. Perform a factory reset: Please remember to backup your phone data before doing this. Once the reset is complete, do not install any apps in your phone yet. Try to check first if the issue still occurs. Check Power Saving Mode: The power saving mode could interfere and block your music-streaming app if turned on. If none of these steps work, it might be a good idea to contact Samsung's customer service for further assistance.
