why does my screen go black when on phone call and need to push speaker or numbers?
.i have a galaxy core prime and when I try to push buttons while on call, phone blacks out. sometimes when trying to push speaker, but mostly when I am calling a business. they will instruct to push "1" for this option or "2" for another option, so on. please help. thank you in advance.
