Seems like the Samsung Galaxy J7 (2016) will soon receive the Nougat update. The device has been spotted on benchmarking website GFXBench, with the listing revealing Android 7.0 OS. This suggests that the Nougat update for the phone is currently being tested by the company.
The handset was launched back in April last year, and it runs Android 6.0.1 (Marshmallow) out of the box. No information on exactly when the roll out will begin. Here's hoping that testing goes smoothly and the update arrives sooner rather than later.
