Samsung Galaxy J7 don't work

[OllisGit]

After starting the "HelloAR Java" on my Galaxy J7 with Android 7.0 a popup appers "Tango Core stopped".
The app shows the message "Searching for surfaces", but the camera is not active

I installed your "arcore-preview-modified.apk"
Compiled the "HelloAR" with the pached "arcore_client.aar"
And the debug-ouput looks like this:
