Juho Sarvikas, the Chief Product Officer at HMD Global has shared on Twitter that the program will follow for other devices like the Nokia 3, Nokia 5, and Nokia 6 soon.
The beta testers will be the first to receive Android 8.0 Oreo, and by testing the software ahead of general release, will help the company to create a smoother experience for the broader audience. Also this update comes with October Security patch which is quite amazing.
To join the beta labs, all you need is a working Nokia 8. Once you sign up and validate your device by IMEI number, you will get the beta software over-the-air. Remember, after your OTA request, the company will push the build to you within 12 hours from time of activation but actually the OTA will become available in a minute and then pull the build directly from Settings > About Phone > System Updates.
If you want to stop testing Android Oreo and go back to Android 7.x Nougat, you can do so by requesting a roll back over the air and if you do not wish to be part of the Nokia phones beta labs program, you can unregister as well. For now all I can say is things look very promising.
