Camera long exposure time

Mobile Galaxy Camera
1

I’m implementing android camera and I want to set long exposure time.

I’m using Camera2 API CaptureReqeust exposure time.
But Galaxy series doesn’t seems to support for long exposure time even over a second.
I got exposure time range from using camera2 api and, it was very short.

However, native camera app of Galaxy s20 can adjust until 30 seconds.

I want to implement the exposure time same as the app.

Could you give me the guide or hint?

You can always request a value beyond the defined capability. It will works. But, the consistency is guaranteed in this case.

I had the same problem with the Galaxy A71 5G, I found that it could take a 30-ish second exposure before it stopped and the camera preview could restart again.

Which is too long and it needs better focus menu
