The feature scan QR-code to add new Wi-Fi connection was shared earlier. This feature will reduce a little bit of work, while trying to connect to a new Wi-Fi network. We will go through how to use this feature.

Android Q: Now scan of Bar-code adds new Wi-Fi connection

In Android Q, the next version from Google, we can generate a QR code with the credentials of my (/ur) Wi-Fi network that outsiders can then quickly scan with their phone's camera to log on. This is also one of the good feature along with Privacy, Settings Panels, System wide Dark mode, Content Preview, Bubble Notifications, App Permissions for the next Android version.

Surely you can find many third-party apps to do this on Android phones, but those apps require you to manually enter your network credentials. But that is not the case in Android Q. Here just tap a button in your Wi-Fi settings will create a QR code to share. And then to scan it, open up your iPhone or Android camera app, scan the code and tap to join. This process is based on the Wi-Fi Alliance's Wi-Fi Easy Connect standard for sharing network credentials with a QR code.

Android Q will also let you add smart-home devices (Like IoT devices) to the Wi-Fi network you manage via a QR code. Wait, there is something here to keep in mind the device used for scanning needs to have Easy Connect Wi-Fi standard for this to work.

You can create QR-code like this

This is how you can create QR-code, scan to connect to a new Wi-Fi network.
  1. Go to Settings > Network & internet > Wi-Fi network's name, tap the gear to the right of your network.
  2. In the Network details window, tap the blue Share button on the right.
  3. Enter your passcode/PIN to generate a QR code with the Wi-Fi name and password.
  4. Optional: One bad thing here is there doesn't seem to be a way to save the QR code, so you have to regenerate it each time you use it. One good suggestion here is take screenshot of the QR code and show that for scanning on your guests phone.
The good thing with this feature is it is quick and easy to connect to New Wi-Fi network but the QR-code provider has to open Wi-Fi settings each time a guest asks for password. But there are 4 more Beta versions to go until we see the actual version. So we can expect some changes to be made on this. If they do not make any changes then use my suggestion (if works) or follow the same procedure shown above.

Scan and connect to Wi-Fi on Android

Here's how you can connect to a New Wi-Fi Network through QR-code.

Method 1:
  1. Go to Settings > Network & internet choose "Add network" at the bottom.
  2. Now, position the Camera viewfinder over the QR code and tap the code.
  3. When the name of the network appears below the QR code, tap it to join the Wi-Fi network.
Method 2:
  1. Camera app can scan QR codes if Lens s turned on.
  2. Open Android's Camera app.
  3. If you haven't used Lens yet, in the camera settings that run across the bottom, tap More.
  4. Tap Lens, and then tap Turn on camera to use Lens.
  5. Finally do last two steps in the above method for a successful connection.

Scan and connect to Wi-Fi on iPhone

On an iPhone and iPad (IOS version > 11) it is much easier to connect:
  1. Open the iOS Camera app.
  2. Position the Camera app's viewfinder over the QR code. When the camera recognises the QR code, it shows a notification.
  3. Tap the notification to join the Wi-Fi network.
That is how you can connect to a Wi-Fi network without entering a password. Hope this feature will be in more use in the coming days after the release of much awaited and excited Android Q version.
