Due to higher volume levels, do not place the phone near your ear when using the speakerphone feature.
Does my Samsung S390G have a Speakerphone feature?
Your mobile device has a speakerphone function. During an active call, you can press the OK (Select Key) navigation key for Spkr On to activate the speakerphone function. For privacy, press the OK key again to disable the speakerphone. The speaker volume can be adjusted with the Volume keys on the top left side of the phone.
Thank you for your feedback!
