I've installed FW v1.0.6 in the SJ9 Strike. You need to put both files on the microcard, not just the bin file as you would with other cameras. I've put a link to the download in comments. SJCam sent me a link, but told me they will put the file on the web site. I made a test video comparing v1.0.4 with 1.0.6. I think it has improved the audio. You can see in my video 1.0 4. was clipping that's why it distorted. Any action camera sounds bad when in a waterproof case, so I think the SJ9 being waterproof sounds OK really. Video also shows how to close the flaps, people have been breaking them? And suggests how to stop misting up.
