The Android Q beta is finally here. At the moment, it’s available only for all three Pixels (yes, even the OG one from three years ago). Let’s take a look at some of the changes that it brings.

Android Q lets users share and join networks on your phone with a QR code. The feature is by no means new and has existed in Android forks such as MIUI for a long time. To generate a QR code, head over to your WiFi settings, tap on the current network and then the “Share” button which pulls up the code. Here, you’ll be prompted to authenticate with your lock screen password or fingerprint first. On a similar vein, if you want to join a WiFi network via a code,  tap the button on the far right of the “Add network” line in the WiFi settings.
