Even if it's no longer in production, ZTE Axon 7 will receive Android 8.0 Oreo soon
If you're still using the Axon 7, which was originally launched with Android Marshmallow on board, you should know ZTE is already working on Android Oreo for this specific smartphone.
We are announcing now that we are already developing Android 8 for the Axon 7, your positive feedback has been inspiring us a lot and made us very happy and because of this we try to get it customer ready as soon as possible for the best customers in the world, and I ask for your understanding because we still need some time to perfect it.
According to ZTE, Android Oreo for Axon 7 is “just around the corner,” but an ETA hasn't been revealed yet. However, there's little chance that we'll be seeing the update this year, but your guess is as good as ours.
