Speaker phone option is greyed out
I have had this issue before, took it to a cell phone repair shop & it was an easy fix..but I can not remember how they fixed it. I don't want to take it anywhere due to it being this easy. The speaker phone button is greyed out when making/receiving calls, which means when someone tries to call or vice versa I can not hear. My music and videos play with sound just fine-the volume is turned all the way up with the ringer being ON.
I have reset network settings and reset all settings and still nothing. Can someone please give me a helpful, real solution to fix this problem?? I have searched all over the internet and found nothing helpful.
