Barcode Scanning with a low res camera (3.2mp) I have two phones, one has a 3.2mp camera, the other has an 8mp camera. I downloaded the 'Barcode Scanner' app on both phones, it works on the 8mp phone but the 3.2mp phone doesnt pick up any barcodes at all.

Is there a way around/fix to get the 3.2mp phone to scan the barcodes?

UPDATE: The 3.2mp camera picks qr barcodes just fine

UPDATE: From the discussion below, it seems the phone doesn't pick up barcodes because it doesnt have Auto Focus. Is there a way I can get around this?
FREE solution: 

I've had success with a fraction of a drop of water or oil over the lens of the camera on my ZTE Score.  It causes bar codes close to the camera to be in focus, and they read reliably.  Enough to form a convex surface, but not so much that it drops off.

The ZTE Score has a smooth back; I dip my finger in oil and, with the lens aimed up, touch the back of the phone where the lens to put a droplet of oil on it.  Then I can turn the phone face up (lens down) and I can scan bar codes.  If the outer surface of your camera lens isn't flat, this likely won't work, but it's worked with my ZTE score and should work with most low-end (fixed focus) phones.

A clear convex on one side, flat and sticky on the other side piece of plastic would do the trick too; I recall seeing stick-on rubber feet that would have served well, but haven't seen 'em and haven't tried that.  

I got tired of doing this every time I wanted to scan a barcode, and just ordered a macro lens.

If the codes don't fit on the screen when in focus, your drop is too big; use less.
