How to disable SMS notification during phone call? I call somebody, or somebody calls me, we are talking. Now, during the call I got SMS and I cannot hear anything because the SMS notification is playing.

So how to disable this notification when call is active? Thank you in advance.

Samsung Galaxy Ace 2, Android 2.3.

Note: I am interested in setting this once and for good. Not something I have to remember to switch off each time I make/get a call.
Since this is of the Samsung Galaxy family, the following may help you:

On my Galaxy S3, the setting is controlled as 'Alerts on call'.

See: Dialer\Call Settings\Call Alert\Alerts on call - uncheck this and calls will not be interrupted with notifications.
