I'm accepting this on the basis that I have several reports of this problem.
However, I don't have any S2 to test with. On Nexus devices, autofocus works as
expected.

This seems to be better in the current version. I'm not sure if something
changed or it's just good luck, but I am usually able to successfully scan
codes now.

Same problem here, scanning normal size qr codes is impossible with my Samsung
Galaxy s2 because the picture stays too blurry. The application is fresh, I
downloaded it two days ago.
To me it looks like the camera is not able to autofocus. I tried to move it
further and closer to the code, but that doesnt help much. Only if I make a
code super big on a computer screen, there is some chance of getting it scanned.

Can you try the following:
1) Make sure you've got the latest version of the app installed.
2) Reproduce the issue, try to focus on a QR code. Make not of the time.
3) Report an issue from within the app (Options > Settings > Report issue). In
the first line, note "issue 209" and the time from step 2. Send.
I'll have a look at the log.

I get the same problem. I have noticed that if I go into the settings on the
pre-installed barcode scanner app on my Galaxy S2 there is a setting titled
"Device Bug Workarounds. No continuous focus - Use only standard focus mode".
This is ticked as default. If I untick it then this app has exactly the same
problem and won't focus. Maybe this identifies the issue?

Interesting. What's your barcode scanner app?

Everyone with the autofocus problem, can you try installing this special test
version:
http://code.google.com/p/bitcoin-wallet/downloads/detail?name=bitcoin-wallet-3.2
4-autofocus.apk
If this works for you, please report back to this issue and tell (again) your
phone model. Thanks!
As always, make sure you've got a backup of your wallet.

The test version works perfectly on my Galaxy S2 GTI9100. Running Android
4.1.2. Scanned QR codes with no problems. Good work!
The barcode scanner app mentioned previously is called "Barcode Scanner version
4.5" from ZXing team.

This is still happening. I just tested using v3.28
Phone model: Samsung Galaxy S2 X (SGH-T989D)
Using a large QR code works fine since it can be placed far from the camera.
But if the code is small (e.g. roughly 1x1 inch) it needs to be placed closer
to the camera, and the image is too blurry to be processed.
It seems like the bitcoin app sets the camera in auto-focus mode.
In case it helps, I notice that if I want to take a picture of the same QR code
using the camera app, the image only shows focused at that close distance when
enabling "macro mode" in the camera settings.
Also, I checked the Amazon app (which is able to scan small barcodes at a short
distance) and I notice that it seems like this app switches focus modes back
and forth when scanning (between macro and non-macro) , and this gives the
algorithm enough time to read the code once it appears focused.

@celino: Can you report an issue through the app, referring to this issue? I
need to determine the exact phone model string for your device.
