title: ADB: missing port in specification
body: <p>I've recently upgraded to Android SDK Platform-Tools version 28.0.2. Version information:</p>
  
  <pre><code>$ adb version
  Android Debug Bridge version 1.0.40
  Version 28.0.2-5303910
  </code></pre>
  
  <p>When using the <code>adb connect</code> command I now get the following error:</p>
  
  <pre><code>$ adb connect 192.168.1.20
  missing port in specification: tcp:192.168.1.20
  </code></pre>
  
  <p>ADB previously connected to devices using TCP port 5555 by default. I am still able to connect to my device by specifying this port number:</p>
  
  <pre><code>$ adb connect 192.168.1.20:5555
  connected to 192.168.1.20:5555
  </code></pre>
  
  <p>However, this is a minor inconvenience to me as I'm used to typing in just the IP address. Is there any way of telling this version of ADB to use TCP port 5555 by default?</p>
