Samsung is once again releasing the next month's security update for a couple of its devices early. The January 2020 Android security patch is making its way to the Galaxy A50 and Galaxy Tab S5e through software updates released for the two devices in some markets. The A50 update is out in Russia and comes with software version A505FNPUU3ASL6. The update for the Tab S5e is out in Panama, Brazil, Chile, Colombia, and Bolivia and sports build number T725XXS1ASL2.
This isn't the first time we're seeing the January security patch on a Galaxy device. The latest Android 10 beta updates for the Galaxy S10, Galaxy Note 10, and Galaxy S9 include the patch as well, but it's only now making an appearance as a part of regular security updates for devices that are running Android Pie. As usual, we have no information on what kind of security vulnerabilities have been fixed in the next security patch, as neither Samsung nor Google will be detailing the patch until a few days into the relevant month.
It's also unclear at this time if there are any improvements or new features included in the updates in addition to the January security patch. The Galaxy A50 update may have some, as the accompanying software version suggests (it has a U instead of an S before the last five letters/digits, which usually means it's more than a security update), and you can tell us in the comments if the changelog provides any details when you're updating your phone.
You can check for the update on your A50 or Tab S5e by opening the Settings app, navigating to Software update, and tapping Download and install. We also have the latest firmware for these devices available in our firmware archive, which you can download and install on your phone or tablet using a Windows PC.
