I have a Samsung J5 2017 (SM-J530F) with Android 7.0 (which should be compatible with Teamviewer Pilot)
but trying to install the Teamviewer Pilot App, I get the message "incompatible" in the android-store
unfortunately, the Samsung J5 device does not support ARCore. This is why you get the incompatibility message from the Google Play store.
Here you can find the list of ARCore supported devices: https://developers.google.com/ar/discover/supported-devices
Thank you & best
