The only solution is disabling Talkback. if you use Narwhal with talkback, It is  recommended choosing the new keymap and the search key as a modifier in talkback. With the old keymap, the alt and shift keys will be trapped by talkback, meaning you won't be able to use them in Narwhal. If you have too much lag, don't ask to improve it. It is due to many factors beyond control, including the notorious bad android latency and your internet connection. Android latency is the biggest one, try a newer phone to get better results, preferably a Pixel or Nexus. latency The lower the latency, the better. Also, wiFi and 4g connections are much faster than 3g. Sending sounds, or screen video, through this app is not possible, and will never be. That's how NVDA Remote was designed. This way we have faster reaction times and less data consumption. If you need sounds, use a traditional remote control app.
