I can only use phone with speakerphone on,not able to hear or talk otherwise
I’ve had this same issue with my husband’s Moto E (2nd Gen). You’ll have to open a ticket and most likely they’ll have to replace your phone (that’s what happened to us). Unfortunately for us, the same issue came back after not even a month later. We got tired of going through the whole process. It took a while for us to get this issue resolved just to have it again. Good Luck.
