Can you post an example photo please, where Settings/Photo settings/"Remove device EXIF data" is set to "Remove device Exif data". Also which version of Open Camera is this (see Settings/About)?
Changing Settings/On screen GUI/"Immersive mode" to "Hide everything" would remove the on-screen icons. A possible workaround to make completely black might be Settings/Camera preview/"Ghost image" if you have a completely black image to supply, although currently the max opacity you can set to is 80%
Hi, make sure Settings/"Camera API" is set to "Camera2 API", then this can be set via Settings/More camera controls/"Shutter sound".
Storage Access Framework
Fixed for the next version - force quitting whilst the SAF dialog is open will mean SAF is turned back off.
Hi, thanks for the suggestions. Which metadata isn't getting removed when using Settings/Photo settings/"Remove device EXIF data"?
The reply is correct - whilst in theory I could use a library to support this, it's likely a large amount of work, and would be difficult to support a range of USB cameras.
What happens if you click on the thumbnail (bottom right when phone held in portrait) after taking a photo? As in they don't show in the gallery? Maybe try a file explorer app to see if that shows files in the relevant DCIM folder?
