[mtselection]

Hi,

I try the sample code Camera2 (untouched),
https://www.b4x.com/android/forum/threads/camera2-still-images-and-videos.83920/
in my Samsung Galaxy S8, with android sdk-26.

When I swicth in camera mode the software stopped with this following error:

Error occurred on line: 156 (CamEx2)
