Flashlight problem

We will have a look at it. thanks.

Refer to other AR reader, most of them can switch on the light for dark envoirnment, so would like to add the same feature in my app. In some case, that may help the image recognition.

No, this is currently not possible. I will put it on our feature request list, but it this might impact the image recognition negatively and therefore won't be making it available.

What is your concrete usecase where flashlight is requried?

As your SDK is holding the camera, then there is no way to switch on the flashlight (LED for camera) by other code.

Is there any solution for this issue?
