About Call Dad
After opening the application for the first time, please enter your Dad's phone number and click on save button. Now exit the application and again open the application, your call will directly go to the saved dad's number. If you have typed the number wrong or you want to change the number, then just type the new number and click on save button, it will overwrite the previous number and when you open the app next time, the call will go to the newly saved number.
It will work finely with Android version 4.0 (Ice Cream Sandwich) to Android version 5.1.1 (Lollipop).For Android version 6 (Marshmallow) and above if the call does not go directly then please go to the app settings page (Settings ->Apps ->Emergency -> Permissions -> phone -> activate it, then it will work finely.
