If you receive during a telephone call with the Samsung Galaxy S5 an SMS message, you will hear a notification tone. If you receive a lot of messages, then the message tone can interfere entirely during the call. That is why we now explain in our article how to disable on the Samsung Galaxy S5 this Message tone during a call.
To do this, open the Home Screen, starting the following Android submenu:
Home Screen --> Menu --> Settings --> Sound & Notifications --> Other sounds --> Call --> Call alerts --> Call signals
Now here you have to the disable the option "Notification during calls" by removing the checkmark from the checkbox.
From now on if you receive a new SMS message during a call on the Samsung Galaxy S5 then you will not hear any more a Message tone.
