If your Samsung Galaxy S8 / S8+ crashes, resets or runs slow, or apps freeze or reset the device, view this.
Restoring your device to default settings helps when the device crashes and resets itself or when apps freeze/hang or reset the device.
Performing these steps resets all system settings (e.g., ringtones, sound settings, display settings, etc.) back to their default values. Personal data such as downloaded apps and media (pictures, videos, music) aren't affected.
