I have a primos truth cam 35. one day I went to check it and the little screen was flashing -50-. I don't know why. I took it home put new batteries in it and tried different sd cards and cleared the old one. It still flashes-50-. If you leave it on long enough it will stop flashing, it will make the noise it makes when it takes a picture but never saves the picture. I bought the camera from a friend so I don't have a owners manual. Is it a broken or what? Anybody have these issues.
