So, I used the app "Remote ADB Shell" on my Android phone to grant the WRITE_SECURE_SETTINGS permission to my AndroidTV (HiSense Smart ATV). In order to grant this permission I had to connect my phone to my TV on my network using RSA key authentication.

It has been a while since I did the procedure, however, I believe that I set the IP address of my TV ( and a port number of my selection (5756). I got a prompt on my TV asking me to allow the RSA key, I pressed accept and was able to send the ADB command necessary.

However, now my TV still listens on port 5756. How can I stop the TV from listening on this port?

    It will always listen for adb on that port, unless you go into the developer settings and disable adb over network. This is totally normal and not a security concern. – acejavelin Nov 18 '20 at 20:13
  • Ok, so I assume if a malicious actor were to try to get in to it, an RSA prompt would appear on the TV and I'd only be in trouble if I accepted it? – Pickinanameainteasy Nov 18 '20 at 22:33
  • Yes, that's correct... Note that would require access to your LAN, either wired or wireless. This type of access could not occur from the Internet. It's fairly safe. – acejavelin Nov 19 '20 at 23:59
