Step 1
On your Android phone, go to google.com/android/beta This page will give you general information about the Android Q Beta release, but more importantly, it will show you whether your phone is eligible or not. Scroll down to see all the eligible Android devices associated with your Google account.Step 2

If you have any eligible devices under your Google account, you will see a blue "Opt In" button below it. Tap on it and agree to Google's Beta program terms and conditions. Pay attention to Google's disclaimer in bold: you will not be able to revert to a public version of Android without wiping the data from your phone first.
Step 3

After you receive a confirmation that you've successfully enrolled your device in Google's Android Beta program, check your phone for software updates. On a Google Pixel phone, this is done in Settings > System > Advanced > Software Updates. If the Beta software is available, it will show up here. Again, a healthy dose of warnings will be delivered.
How to remove the Android Q Beta
If you keep the Android Q Beta installed on your phone, you will eventually receive the stable release of the OS when it's becomes available later this year. In this case, no data will be wiped. But if you want to remove the Beta software and go back to a stable Android 9.0 Pie release, the data on your phone will be erased. To go back from Android Q Beta to Android Pie, follow the link provided in Step 1 and choose "Opt Out" under your device.
