Basics
• When using the speakers, such as when playing media files, do not place the device
close to your ears.

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.

– If you attach metallic stickers on the antenna area of the device
– If you attach a device cover made with metallic material to the device
• 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.
