Now that Samsung is putting the batteries into Android updates, movements in firmware are very common. Those who can not wait for the arrival of the OTA on their mobile can still use Odin to install the firmware “by force”. First, yes, you need to download the firmware.
As an alternative to websites that collect Android firmware like Sammobile, which limit download speed, the new Samsung Firmware Downloader app lets you download the latest firmware of any Samsung mobile directly from the source

More advanced Samsung users, those who like to fiddle with their phones by installing recovery mode, Magisk, and / or force-updating firmware, have one more tool at their disposal. Samsung Firmware Downloader.
It is a simple and cross-platform application with which you can easily download the firmware of any Samsung device, directly from Samsung, without intermediaries, advertisements or speed limits. It is an open source application available for Windows, Mac, Linux, and even Android. It is therefore possible to download the firmware of your Samsung mobile, from your Samsung mobile.
To use the application, you must enter two data: model name and CSC code of the region. Then press Download and, if all went well, the name of the latest firmware will be d isplayed, which you can download with the button Download
The application is extremely simple, so it will start the download without further delay, showing you the remaining time. An interesting addition is that the download can be stopped and continued later, something useful considering that the firmware is around 4gb these days. Once the firmware is downloaded, it is decrypted automatically (which you can also do manually in the tab Decrypt).
The app downloads and decrypts the firmware, but what you do with it next is up to you. You will need an app like Odin to flash it, but remember that any operation like this comes with some risk, so it is best to abstain from it unless you are sure what you are doing.
