Basics
• When using the speakers, such as when playing media files or using speakerphone,
do not place the device close to your ears.
• Be careful not to expose the camera lens to a strong light source, such as direct

the camera image sensor may be damaged. A damaged image sensor is irreparable

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
appearance may be affected.
