    I have the same problem. Before taking the picture, the image in the view screen looks fine. After I push the shutter button, the flash goes off and the picture is taken. All of the pictures come out very dark.

    I have tried adjusting the exposure settings on some of the manual modes, and it helps a little, but it doesn't completely solve the problem. Furthermore, the exposure cannot be adjusted in the auto mode.

    Mine is doing the same thing. Dark pictures when i use the flash. It's like the camera & flash are out of sync...

    I have the same issue but not only in Auto mode, my flash just doesn't work it won't even shoot most times and if it does an extremely dark pic comes up.

I sent my camera into Canon for repair. They said the flash was malfunctioning, and there was something wrong with the flash exposure control. The repair cost about $87. It took approximately 10 days from the time I sent the camera in until the time I got it back.

I just got my A640 back from Canon's repair center. Same problem as everyone...dark pics in Auto mode with flash. Program and other manual / Tv / Av modes works ok. With shipping it cost me $93, took about 10 days, but they fixed the flash, replaced the outer shell/ top covers, cleaned it up, and made it look new. My photos in Auto now look fine when using the flash. I was considering a new G10 for Christmas, but they replaced the outer shells (which was the dark grey) with spiffy Black. It's looks cooler now, so perhaps I'll keep it for a while.

My camera's flash is not working and the icon of flash keeps blinking every time i try to click a photo. Also the camera works fine when I switch off the flash.

If its blinking then it meas that it is not adequately charged. The flash indicator will turn to steady orange if its properly charged.

if you have the camer in manual on the back on the round wheel there is a small lightning bolt looking thing (a wavy line pointing down) click that and it should cycle through the flash options, normally the sybol with a circle and line through it means no flash.

As for photo tips, no flash, maybe side light it with a lamp or put it beside a window, this might catch the shadows in the glass so the engraving comes out more.
