Hi, I bought my N70 last summer. I like the camera, but its back cover has always been bothering me. If I push and release the back cover back and forth, I can hear the clicking sound just like clicking a computer mouse button. It is annoying every time I try to take a picture. The back cover can also slide up and down against the camera main body. All of above happens with or without film loaded. Has anyone had similar experience with the N70? Or should I have it repaired? The one year warranty is going to expire. Thanks Kezhong
