Thanks, it works, but it goes to this screen. Says not available and hits in x and y plane, says android true on startup. Blank screen, think it might be the phone or I should be using 4.17 version not sure, maybe 4.18 sample only works on 7.1 androids. Just had to set it to android 24 like you said.
Edit: Looked at ARCore says only google pixel and s8 phones support ARCore preview, was using S6, my bad
