Hi at all!
My problem begin when i HangUp a call before answer. 2 italian operators, Wind and Vodafone, in this case, send a SMS from the contact that call with some text like "I call you at 12 am"
So, when i intercept a new SMS by SystemState.MessagingSmsUnread>0, i check if the Sender of last message is the number of the call that i HangUp first, so i delete the new sms and set the registry key of MessagingSmsUnread to 0.
With this system i can hide popup notification and LED notification, but i cannot stop play the sound of new SMS.
How can i do?
