My phone stopped charging, I called a couple places and found this place with the most reasonable price and the reason I decided to take my phone was that the person who answered the phone (Mason), gave me a lot of information and said he will diagnose it for free, if he has to replace the charging port it will be done the same day which it was very important to me to get my phone fixed as soon as possible. He even gave me a loaner phone till my phone is ready to be picked up! That's why I feel this place is the most professional repair shop for cellphone. Thanks again Mason!
