I just bought a certified refurbished gear s3 classic on Amazon, and when I got it today, I found that it only turns on while charging, and that I cant connect to my phone. When it is about to, it turns black and disconnects. I have also tried to turn it on without connecting to a phone, and when I get past the pin code, it shuts off. I just got scammed I believe. The charge numbers are very inconsistent as well, and overlaps other messages on my screen.
