Hi! The only time i ever get blue lines on my camera is when the setting is on Automatic when im inside the house in bad lighting (when its dark and you've got the house lights on) When this happens i just switch it to night (with the resolution set to high) and i get a really awesome picture! Though the camera does move a little slow when its on the night mode! When im outside through the day, i switch it to automatic and again the picture quality is brilliant and the camera responds a lot faster. The only thing that stresses me out is texting. When i start a text, the phone responds really fast, but it seems the futher i get into the message, the slower the phone responds, and i end up waiting ages for it to scroll to the next letter! Has anyone else experienced this? Also, sometimes my camera wont come on, i'll press the button and it will say "please wait", and i wait and then it will just bring me back to my main screen, after a few tries it usually works. I've also had trouble with the phone turning itself off when i tried to send picture messages, but i think that had something to do with not having a full signal bar.
