Everything works fine except the built-in QR code scanner.

Does it not focus? If so, try to disable the checkbox "Continous Autofocus" in the settings.

Some background:
The general idea in embedding a QR code scanner within Bitcoin wallets is: security. If you rely on a third-party barcode scanner app which may not be open-source (so that you can check it does not something malicious) someone could trick you into installing a malware barcode scanner which does not behave honestly.

For example: I could easily write a barcode scanner app, which works perfectly for weeks as expected (so that you won't suspect anything), but only if you scan a payment request which is - let's say greater than 5 BTC - my malicious barcode scanner returns one of my address instead of the real one you just scanned. If you would't look carefully enough you might end up sending your funds directly to the attacker.

@jan:
Just noticed last weekend on a friend's phone that on international Galaxy S2 (Samsung GT-I9100, sorry have no further build details) the autofocus also only works, when "Continous Autofocus" is disabled.
