'Samsung Devices API 12 does not Dial code automatically

We are trying to dial the code

  "*%2306%23" = "*#06#"

through the adb command to fetch the information about the IMEI

 adb -s "DEVICE SERIAL" shell am start -a android.intent.action.DIAL -d tel:*%2306%23

The connected device shows the code on the screen but doesn't auto-dial. But, when we try to dial manually it's working fine.

The device is connected and the developer option is enabled.

Any help would be appreciated.

The intent that you are sending only opens the dialer app and enters the number, it does not dial. In order to dial you have to press the call button - adb shell input keyevent KEYCODE_CALL, but...
you are not dialing a regular number, you want to enter some code, so you have to open the dialer and enter the code symbol by symbol:

adb shell am start -a android.intent.action.DIAL
adb shell input keyevent KEYCODE_STAR
adb shell input keyevent KEYCODE_POUND
adb shell input keyevent KEYCODE_0
adb shell input keyevent KEYCODE_6
adb shell input keyevent KEYCODE_POUND
