title: Is there a way to detect a pressure power on screen?
body: <p>I need to check the power with which the user pressing the screen, like force touch or 3D touch.</p>
  
  <p>Googling it, I saw that Android Q will support deep touch. It looks like a new constant added in Android Q:
  <code>public static final int CLASSIFICATION_DEEP_PRESS</code></p>
  
  <p>So, the first, is it like a hardware feature on the phone, not software, so that only some phones could be tested on it? Second, is it true that until Android Q released, we can't measure screen pressing power? If it's not, how can I achieve it now?</p>
