Mo, I think was his name, was very friendly and informative. I took in my Galaxy S4 the mic was broken. I had previously went to another place to get the LCD screen replaced because it was broken and they broke the mic. People couldn't hear me when I talked unless I used my earpiece. He offered to clean it and it still didn't work he knew exactly how they broke the mic and fixed it for a good price. Very happy with the customer service and will return if I need anything else.
