Black screen in preview. Session 9: Exception while stopping repeating

[Arturo Sanjuan]

Hi everyone.

I have developed an app that uses the camera. We chose to use de camerax 1.0.0-beta04 I took the sample from https://github.com/android/camera-samples/tree/master/CameraXBasic, 

the app run fine in almost all devices I had proved but in in this samsung SM-J710MN API:27 this error appears:

Hi , 

Sorry for missing your post.
Does this issue happen 100% every time you run CameraXBasic ?   
We also encountered many issues on this device SM-J710MN  as well.   Though these are likely device's issues ,  we will try as much as we can to work around it if possible.   

Thanks 

Scott
