From the beginning with my Galaxy S3 Mini people were having difficulty hearing me during calls. We would be in the middle of a conversation and they'd lose my voice. The calls would not drop. After 10-20 seconds then they'd be able to hear me again. I exchanged my phone on Monday for a "Refurbished" Galaxy S3 Mini. I've had this phone for 48 hours, I've made 3 calls, and 2 of those 3 calls have had the same problem. The person on the other end is having difficulty hearing me. I have no trouble hearing them. But I spend half my conversation saying "Can you hear me now?" What is going on?
