Those who have signed up for the Android Pie beta on their Galaxy S8 or Galaxy S8+ already have the January 2019 security patch on their devices, but Samsung isn't leaving those on Oreo behind. The Galaxy S8 and S8+ are getting a new software update that brings the latest security patch and is rolling out in a number of European countries. The software version for the update is G950FXXS4CRLB.
The Galaxy S8+ isn't getting the same update just yet, but it will only be a matter of time before it does. The update only has the new security patch to offer, which should surprise no one. The Android Pie update is what Galaxy S8 owners will have to wait for to see new features, and that update isn't going to arrive before April for most countries. Samsung is likely to keep releasing regular security updates till then, both in markets where the Android Pie beta program is available and in markets where it isn't.
You can grab the new Galaxy S8 update over the air from the Settings » Software update menu on your phone. Alternatively, you can download the firmware for the new software from our firmware database (Galaxy S8 | Galaxy S8+).
