Remember the Galaxy J7 Nxt? Samsung does, and so does its security team, who worked hard on the best birthday gift there is: peace of mind. The June 2021 security patch has started making its way to select Galaxy J7 Nxt models in Argentina and Thailand. This particular software release is identified by model number J701FXXUACUE5 or J701MUBUBCUE1. Given how it's targeting the international model of the modestly-specced 2017 device, expect to see it in your vicinity sooner rather than later.
Oh, and while you shouldn't confuse the Galaxy J7 Nxt for the Galaxy J7 (2017), we won't blame you if you do. After all, the latter has also started receiving the very latest security update from Samsung this past weekend. These two entry-level handsets from forever ago are enjoying a better level of support than the latest flagships from Xiaomi, OPPO, and co. By several orders of magnitude, mind you.
The Galaxy J7 Nxt puts even (non-Samsung) flagships to shame, update-wise
As for the update at hand, the June 2021 security patch level has been rolling out worldwide for just over a month now. Throughout that period, Samsung initiated 147 other deployments across 36 countries, present company not included. As always, you can try to speed things up a bit by navigating to Settings > Software update > Download and install. Right now, this method is most likely to work if you're located in Thailand or Argentina.
Otherwise, your best best is to proceed to our firmware archives, download the full system images for your Galaxy J7 Nxt and flash them to the device manually. If you're itching to get your hands on the update ASAP, that is.
