Nokia Android Update Policy
All Nokia branded Android phones get two major Android updates after their release. The only exception to this rule is the Nokia X series, launched in 2021. The Nokia X series is promised to get three major Android updates after its release.
To put it simply: If a Nokia phone is released with Android 10, it is promised to get Android 11 and Android 12 updates. If the phone is Nokia X phone, it will also get third update - in this case, Android 13.
