I bought my digital camera a week and a half ago and it worked perfectly until yesterday. When I put my camera on the Auto Adjustment Mode and I try to take a picture/press the shutter button halway down, it sometimes changes to another mode and then sometimes returns to the previous one for no reason. I know I didn't even touch the mode dial, so it's not the problem! Furthermore, when I put it on the Playback/Edit mode, it sometimes stays on the Auto Adjustment Mode as if I hadn't changed it. There's also another problem, when I zoom at something, I can't take a picture 50% of the time. I press the shutter button halfway down and when everything's okay, I press it fully down, but it doesn't take a picture.
I don't remember having any of these problems before yesterday and I haven't done anything to my camera so that it could be weird like that. If someone got this problem, please tell me what I should do. If you want more information or if I was not clear enough, just tell me. Mt first language is not English, so that might be why. Thanks for helping me.
