Finally myself solved the problem with SAMSUNG GALAXY GRAND I9082 after pressing the call button the screen shows calling.At this time simply press and hold the HOME button for one to two seconds the apps which are on the home page will displayed on the screen and you can select the desired apps ,you can add any app to the homescreen .To show which apps you drag and drop the desired apps on to the home screen and atleast one or two times you have to open the app ,,,because when you open any app and after returning to home screen this apps which are recently opened becomes running process behind the screen in the RAM ......so when call is in progress holding HOME button for one second will shows the running apps .... touch which app you want ,it will opens...
100% working ....iam so happy...

Try pressing the menu button then contacts.
