Programmatically adjusting flashlight brightness

Mobile Galaxy Camera
1

Hi,

I’m trying to write a flashlight app for Android. The standard API to turn on the flashlight is:

val cameraManager = getSystemService(Context.CAMERA_SERVICE) as CameraManager
        try {
            val cameraId = cameraManager.cameraIdList[0]
            cameraManager.setTorchMode(cameraId, true)
        } catch (e: CameraAccessException) {
        }

However on my Galaxy S10 just turning on like this sets the brightness at 3 of 5. I’m wondering if the flashlight brightness is accessible to a developer, perhaps by modifying a system file like what used to be possible with some HCL phones.

Hi,
There is no official API or SDK for this, unfortunately.

I already read all SO threads that exist on the subject I think, but thanks.
