Samsung Galaxy S9 has been noticed with the Android 8.1

The Samsung Galaxy S9 has been noticed in a Geekbench listing with Android 8.1. The Samsung Galaxy S9 and S9+ have been launched in March running Android  8.0. 
Samsung didn't provide any guidelines about the exact time when this update will come, and we already know that we can't take benchmark listings for certain, but at least now we know that the update is in development.

We are hoping that the testing will go well and that the official release will come soon.
