Had the same problem with my BLU Life Play X, and I didnt once drop it or get water on it. The charging port simply quit working. I think this is a recurring problem with BLU manufactured phones, I'm on my second phone from them within the past year and they simply do not last longer than 6 months (based off my own experience.) What I was able to do as a temporary fix was to bend the USB charging part (The silver part that plugs into the phone)just enough to get it to charge. Eventually I had to lean it against something and put weight on it to get a response from the phone. It doesnt help much but will charge your phone temporarily enough to save your pictures and videos before you need a replacement.
