Get Android Phone Model programmatically , How to get Device name and model programmatically in android?

Yes: Build.MODEL.

Actually that is not 100% correct. That can give you Model (sometime numbers).
Will get you the Manufacturer of the phone (HTC portion of your request):

 Build.MANUFACTURER

For a product name:

 Build.PRODUCT

Kotlin short version:

import android.os.Build.MANUFACTURER
import android.os.Build.MODEL

fun getDeviceName(): String =
    if (MODEL.startsWith(MANUFACTURER, ignoreCase = true)) {
        MODEL
    } else {
        "$MANUFACTURER $MODEL"
    }.capitalize(Locale.ROOT)

Build.DEVICE // The name of the industrial design.

Build.DEVICE Gives the human readable name for some devices than Build.MODEL

Build.DEVICE = OnePlus6
Build.MANUFACTURER = OnePlus
Build.MODEL = ONEPLUS A6003

You can get the phone device name from the

BluetoothAdapter

In case phone doesn't support Bluetooth, then you have to construct the device name from

android.os.Build class

Here is the sample code to get the phone device name.

public String getPhoneDeviceName() {  
        String name=null;
        // Try to take Bluetooth name
        BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
        if (adapter != null) {
            name = adapter.getName();
        }

        // If not found, use MODEL name
        if (TextUtils.isEmpty(name)) {
            String manufacturer = Build.MANUFACTURER;
            String model = Build.MODEL;
            if (model.startsWith(manufacturer)) {
                name = model;
            } else {
                name = manufacturer + " " + model;
            }
        } 
        return name;
}

You can Try following function and its return your phoneModel name in string format.

public String phoneModel() {

    return Build.MODEL;
}
