I didn't have access to sms icon. I mean this app ask for permission to sms but it doesn't have sms icon. This is boring, so i have to use my default sms app after giving call permission to sms. Call app didn't have sms icon. An icon only shows when sms comes in and both call app sms and default sms app pop up together. Solution. Create a separate icon for sms and work on double pop up.
