Many smartphone OEMs have been coming up with their own beta programs to offer users hands-on unreleased versions of Android. Samsung has been one of the OEMs who started its beta program with Nougat, last year. Entering into the territory is Nokia, who has relaunched their Beta Labs program for Nokia smartphones. It is for the users who want to do a test run of upcoming Android 8.0 Oreo update on the Nokia 8 smartphone.

To recall, Nokia introduced its first Nokia Beta Labs program back in 2007 that was for testing Nokia app in beta forms. The program expanded to a variety of apps and then it was renamed to Lumia Beta Apps after Microsoft acquisition.
