I can confirm that this happens with: - gonk v18d - gecko b2g-inbound:6534b40ed186 - gaia master:3446a7b7aca75769981c1da7158895e85e7b6583 It seems more likely to happen if the AE algo hasn't completely blown-out the exposure when you re-tap.

I just checked with the WebIDE, and the camera is reporting that flashMode is set to "auto". I've also confirmed that we set the flashMode to "auto" on app start, and with the above STR, don't change it. It looks like the driver is losing its mind. Wesly, can you raise this issue with our partner?

Youlong, as discussed you can verify w/ base image first to see confirm if there is low level driver issue. Tks.

Hi Youlong, I verify again on v18D but it indeed can be reproduced with it. Please help to check it again, thanks. Note, the reproduce rate may be very low. You can tap the screen to get manual focus again and again around a dark environment then it has chance to reproduce it.
