AT&T has released a new software update for the budget Samsung Galaxy Express 3 smartphone that was released in April last year.

The new update brings the October Android security patch to the phone, along with bug fixes and other improvements. There’s also the fact that this update will patch the KRACK Wi-Fi vulnerability. That makes this an important update for users to install.

The software version of this update is J120AUCS4AQJ2 and it only weighs about 23MB in size. If you’ve got the Galaxy Express 3, then you should receive this update via OTA very soon. In case you have already received the notification for this update, then we recommend you install it right away.

If you haven’t received the update, then you can check for it manually by opening the Settings app and navigating to System > About device > Software update. The Express 3 runs on Android 6.0.1 Marshmallow and will not get any further software updates. However, if you own the Galaxy Express 3 Prime, then you should’ve received an update to Android Nougat.
