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
sunlight. If the camera lens is exposed to a strong light source, the camera image
sensor may be damaged. A damaged image sensor is irreparable and will cause
dots or spots in pictures.
• If you use the device with its glass or acrylic body broken, there may be a risk of
injury. Use the device only after it has been repaired at a Samsung Service Centre.

– If you attach a device cover made with metallic material to the device
– If you cover the device's antenna area with your hands or other objects while
using certain features, such as calls or the mobile data connection
• Using a Samsung-approved screen protector is recommended. Unapproved screen
protectors may cause the sensors to malfunction.
• Do not cover the proximity/light sensor area with screen accessories, such
as a screen protector, stickers, or a cover. Doing so may cause the sensor to
malfunction.
