Samsung Galaxy J7 (2015) was launched with Android Lollipop out of the box. Last year, the device received the Android 6.0.1 Marshmallow update. Sometime in June this year, the device was spotted with the Android Nougat OS on the Wi-Fi Alliance website.
After a couple of months, the original Galaxy J7 has been spotted running the Android Nougat OS once again by the folks at SamMobile. However, we need to mention that the update is yet to be rolled out to the smartphone. This time too, the Android 7.0 Nougat based Galaxy J7 (2015) has been spotted on the Wi-Fi Alliance website. From the listing, it is clear that Samsung is testing the Android 7.0 on the original Galaxy J7 but there is no clarity on when the update will be rolled out.
Notably, being spotted on the Wi-Fi certification website does not mean that the roll out of this update is imminent but it does point out that the Android 7.0 Nougat update for the Galaxy J7 (2015) is in the pipeline.
Going by the listing on the Wi-Fi Alliance website, the Samsung Galaxy J7 (2015) will arrive with support both dual-band Wi-Fi and Wi-Fi Direct. The listing does not reveal any information regarding smartphone expect that the device will get the Android 7.0 Nougat in the coming weeks or months. Furthermore, the listing shows that the model number of the device is SM-J700T and certification ID WFA64700.
Though there is no mention on when the update will be rolled out to the users, as it has received the certification twice, we can expect it to be rolled out soon.
