Photo quality is poorer than the preview

•The quality of your photos may vary, depending on the surroundings and the photography techniques you use.

•If you take photos in dark areas, at night, or indoors, image noise may occur or images may be out of focus.

Error messages appear when opening multimedia files

If you receive error messages or multimedia files do not play when you open them on your device, try the following:

•Free some memory by transferring files to a computer or deleting files from your device.

•Ensure that the music file is not Digital Rights Management (DRM)-protected. If the file is DRM-protected, ensure that you have the appropriate licence or key to play the file.

•Ensure that the file formats are supported by the device. If a file format is not supported, such as DivX or AC3, install an app that supports it. To confirm the file formats that your device supports, visit www.samsung.com.

•Your device supports photos and videos captured with the device. Photos and videos captured by other devices may not work properly.

•Your device supports multimedia files that are authorised by your network service provider or providers of additional services. Some content circulated on the Internet, such as ringtones, videos, or wallpapers, may not work properly.

Another Bluetooth device is not located

•Ensure that the Bluetooth wireless feature is activated on your device.

•Ensure that the Bluetooth wireless feature is activated on the device you wish to connect to.

•Ensure that your device and the other Bluetooth device are within the maximum Bluetooth range (10 m).

If the tips above do not solve the problem, contact a Samsung Service Centre.
