Why I cannot get the Galaxy S8 Android Oreo update for Galaxy S8 and S8+?
Android updates for Galaxy S8 and S8+ are managed by Samsung, together with local carriers/distributors.
In different regions, the firmware may be slightly different as well.
Therefore, Android Oreo update for GalaxyS8 and S8+ are not rolled out at the same time in different regions.
The difference can be as vast as a few months.
When the update is ready, in most regions, it will be rolled out in a staged manner to prevent the server from being overloaded. Therefore, some phones may get the update a few days earlier than the others (in the same region).
This difference usually is about a few days depending on the region and the carrier.
So, if other Galaxy S8 and S8+ owners in your region got the update, but you haven’t, you may have to wait a few days.
If I bought Galaxy S8 and S8+ from other countries, will I get Galaxy S8 Android Oreo update?
It depends.
The physical updating servers are hard-coded into the firmware. Your physical location does not matter.
In other words, as long as your Galaxy S8 or S8+ can connect to the updating server, you can still check and download the update.
But there is an exception.
Some carriers (especially a few USA carriers) may block the connection to their server if you do not have a SIM card from them on the phone.
There is no Android Oreo update for Galaxy S8 and S8+ in my region, can I flash firmware for other regions?
You are recommended NOT to flash firmware that is not released for your region.
In different regions, the 4G LTE bands may be different. Galaxy S8 and S8+ do NOT enable all bands in all regions. You may get many connection issues if you use the firmware for other regions.
Besides, there may be some variations of a few hardware components for Galaxy S8 or S8+ in different regions.
Some of such variations are documented. For example, Galaxy S8 and S8+ sold in the USA used Qualcomm chips. But in the international market, Samsung’s own chip was used.
Some of the variations are not released to the public, for example, some sensors may be sourced from different suppliers.
So, the driver (which is part of the firmware) needed can be different in different regions.
Anyway, it is NOT recommended to flash Galaxy S8 Android Oreo update firmware that was NOT released for your Galaxy S8 or S8+.
Since Android is open sourced, why I cannot install Android Oreo for Galaxy S8 and S8+ from Google?
First, because Android is free and open-source, anyone including Samsung (and you) can modify Android.
Android in Galaxy S8 and S8+ is different from the stock Android. Samsung hacked it heavily to differ their Android from other vendors.
Second, you also need drivers for hardware components. The drivers in Android Nougat may not work in Android Oreo.
Only Android manufacturers have a detailed list of all hardware components, and only they can demand details of the components from the suppliers.
You can get Android Oreo update from Google only if you are using a Pixel, Pixel 2, Pixel XL or Pixel XL 2. A few Nexus phones can also get Android Oreo update.
