Thanks for the bug report. Although flash is indeed controlled by software, this exact behaviour in this case is handled by the camera driver. How do other third party camera applications behave? In Open Camera, does Settings/"Camera API" show? If so, try "Camera2 API" do any better? (With this option, Open Camera will have more control over the flash timing/behaviour.)

Just to check, how did you test your sensors are calibrated? Open Camera has its own calibration in case that helps: Settings/More camera controls/"Calibrate level angle" (perhaps first try "Reset" in case that got set somehow; but if not, follow the instructions to calibrate).

Thanks to the other poster for giving the answer. Just to add, there's also Settings/Photo settings/"Save preview shots" (i.e. turn it to off) if you don't want an on-screen icon. I'll add some kind of indicator when this feature is turned on, as it currently isn't obvious (if one doesn't have the preview shows icon enabled).

I tried MotionCam Pro Trial on my Galaxy S24+ - whilst this sees the separate physical lenses, it doesn't seem to support them as a single logical camera (where one can zoom continually between lenses). This is one of the problems with exposing hidden lenses directly, you don't get the connection between physical and logical cameras. Even if hidden cameras open, they may result in buggy behaviour including crashes and ANRs, leading to poorer performance on Google Play's metrics, and me wasting time...

Thanks for bug report - this is likely device dependent (as launching from lock screen differs between manufacturers), I'll see if I can reproduce on my Pixel 6 Pro. Regarding running in background - note that Open Camera appearing after turning screen off and on doesn't necessarily mean Open Camera was continuing to run continually - turning the screen off in Android means applications will still be put into a paused state, and then resumed when the screen turns on (or at least that's what should...

Open Camera doesn't have any direct support for optical zoom I'm afraid, and likely hard to fix (I don't have any devices with optical zoom - seems to be less common these days). I don't know if other third party camera apps show this issue?

Exposure in repeat mode sporadically goes haywire
