About digital cameras.....?

I'm having a problem with my camera...It's a samsung digimax A 503....a few times it has taken Awesome pics, but every so often, and now currently...it takes horrible photos.....it's not getting any god detail in...almost blury, and it didn't always do this...It has been like this for a week or two now and I don't know what to do...before it only lasted a day or so....Is it a setting? I cleaned it and it still isn't working...any suggestions?

then how do you get it off macro?

Make sure you are not putting your finger over the infrared focus window.

Clean the window.

Make sure the camera isn't set on Macro (usually an icon of a tulip)

I hope one of those works. They are the most common problem.

go into the menu
and find the reset tab
that should restore it
