I can see the qr code in the camera, but it won't do anything. I'm assuming there should be a moment when the phone goes like \"okay I saw that's a qr code\", but nothing happens. I think the problem may be that the camera is a bit out of focus.\r\nSamsung galaxy s3, signal 3.5"},"comment":{"url":"https://api.github.com/repos/WhisperSystems/Signal-Android/issues/comments/162325118","html_url":"https://github.com/WhisperSystems/Signal-Android/issues/4637#issuecomment-162325118","issue_url":"https://api.github.com/repos/WhisperSystems/Signal-Android/issues/4637","id":162325118,"user":{"login":"ndevln","id":5631424,"avatar_url":"https://avatars.githubusercontent.com/u/5631424?v=3","gravatar_id":"","url":"https://api.github.com/users/ndevln","html_url":"https://github.com/ndevln","followers_url":"https://api.github.com/users/ndevln/followers","following_url":"https://api.github.com/users/ndevln/following{/other_user}","gists_url":"https://api.github.com/users/ndevln/gists{/gist_id}","starred_url":"https://api.github.com/users/ndevln/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ndevln/subscriptions","organizations_url":"https://api.github.com/users/ndevln/orgs","repos_url":"https://api.github.com/users/ndevln/repos","events_url":"https://api.github.com/users/ndevln/events{/privacy}","received_events_url":"https://api.github.com/users/ndevln/received_events","type":"User","site_admin":false},"created_at":"2015-12-06T16:00:09Z","updated_at":"2015-12-06T16:00:09Z","body":"I think it's not quite as simple as that, since this function allows you to get a full take an the devices communication over Signal. For example the verification of the fingerprint of your contacts is done by an external app (f-droid barcode scanner in my case).  But for this scan they use an internal approach, which I think is a deliberate choice.\r\n\r\nSecure design is hard to get right and I think @moxie0 has put some thought into it."}}
