•
Be careful not to expose the camera lens to a strong light source, such as direct

If dust or foreign materials enter the microphone, speaker, or receiver, the device’s
sound may become quiet or certain features may not work. If you attempt to remove
the dust or foreign materials with a sharp object, the device may be damaged and its

Connectivity problems and battery drain may occur in the following situations:
–
If you attach metallic stickers on the antenna area of the device
