As it was explained earlier, Nokia 2 has been a problematic device for Nokia Mobile to update. The device comes with 1GB of RAM and Android Nougat, while Android 8 Oreo requires 2GB of RAM, but Android 8.1 Oreo is ok with 1GB of RAM. So HMD tried to upgrade the 2 to Android 8.1 Oreo by also porting some features from Android GO, Google’s version of Android for low end phones. Nokia 2 uses regular Android so it cannot directly be upgraded to Android Go.
Anyways, HMD Global, after months of beta testing, did finish Android 8.1 Oreo for Nokia 2, but the performance of the device with the new OS is worse compared to Nougat, as was basically stated by HMD on the website. Users that want to upgrade their Nokia 2 to Android Oreo, and are willing to deal with slower performance and more features, can upgrade to Oreo via Nokia Mobile dedicated upgrade site.
The newly established site allows users to sign into HMD’s Android Oreo program for Nokia 2 and request an OTA (over the air) upgrade. Here comes a big BUT: You can request an update, but the update has to be pre-approved by your carrier and allowed for your market. Because of that, Android Oreo (at the moment) for Nokia 2 isn’t available in a bunch of countries. The list follows down below:
Albania, Armenia, Austria, Azerbaijan, Belarus, Bosnia and Herzegovina, Chile, Croatia, Cyprus, Czech Republic, Estonia, Georgia, Greece, Hungary, Indonesia, Ireland (Except Vodafone Ireland), Israel, Kazakhstan, Latvia, Lithuania, Macedonia, Moldova, Mongolia, Montenegro, Peru, Poland, Russia, Serbia, Slovakia, Slovenia, Ukraine, United Kingdom, Uruguay
