There is a separate mobile phone model that can use ARCore. So you should check the list --> Go and check

How to use ARcore

Before you start,

1. Modify your AndroidManifest.xml to include the following entries:

<uses-permission android:name="android.permission.CAMERA" />

<!-- Limits app visibility in the Google Play Store to ARCore supported devices
     (https://developers.google.com/ar/devices). -->
<uses-feature android:name="android.hardware.camera.ar" />

<application …>
    …

    <!-- "AR Required" app, requires "Google Play Services for AR" (ARCore)
         to be installed, as the app does not include any non-AR features. -->
    <meta-data android:name="com.google.ar.core" android:value="required" />
</application>

2. Ensure that your app has at least the required minSdkVersion in your app's build.gradle

android {
    defaultConfig {
        …
        minSdkVersion 24
    }
}

3. Make sure your project's build.gradle file includes Google's Maven repository:

allprojects {
    repositories {
        google()
        …
    }
}

4. Add the latest ARCore library as a dependency in your app's build.gradle file:

dependencies {
    …
    implementation 'com.google.ar:core:(your_version)'
}

Then, you can use ARcore at Android Studio.

Use ARcore

1. First, create AR view
arFragment.setOnTapArPlaneListener(new BaseArFragment.OnTapArPlaneListener(){
            @Override
            public void onTapPlane(HitResult hitResult, Plane plane, MotionEvent motionEvent) {
                //when user tap on plane, we will add model
                if(selected == 1)
                {
                    Anchor anchor = hitResult.createAnchor();
                    AnchorNode anchorNode = new AnchorNode(anchor);
                    anchorNode.setParent(arFragment.getArSceneView().getScene());

                    createModel(anchorNode,selected);
                }
            }
        });

2. Create augmented name card

private void createModel(AnchorNode anchorNode, int selected){
        if(selected == 1){
            TransformableNode ar_text = new TransformableNode(arFragment.getTransformationSystem());
            ar_text.setParent(anchorNode);
            ar_text.setRenderable(tigerRenderable);
            ar_text.select();


            addName(anchorNode, ar_text, card_content);
        }
    }

3. Show the content to the AR view after clicked

private void addName(AnchorNode anchorNode, TransformableNode model, String name){
        TransformableNode nameView = new TransformableNode(arFragment.getTransformationSystem());
        nameView.setLocalPosition(new Vector3(0f, model.getLocalPosition().y+0.5f,0));
        nameView.setParent(anchorNode);
        nameView.setRenderable(content);
        nameView.select();

        TextView txt_name = (TextView)content.getView();
        txt_name.setText(name);

        txt_name.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View view) {
                anchorNode.setParent(null);
            }
        });
    }
