Looks a bit like a 2.3 specific issue, I'll check on my Galaxy S2.

Attachment: Get the local preview surface (line dropped during merge)

Looks like this accidentally got deleted when merging.

The video works correctly now, but the audio/microphone doesn't work.

Is this a different bug?

Comment 6

[Gian-Carlo Pascutto [:gcp]]

Yes, this fix was specific to video. (Audio also worked in my testing so more info would be needed anyway)

Comment 7

[Gian-Carlo Pascutto [:gcp]]

Did you file a bug for the audio issue or was it a false alarm?

Comment 8

[Flaviu Cos]

Sorry for the delay, I logged Bug 1134991 for the audio issue.
