Samsung has already refreshed one of its mid-range series for 2017 and some of its other series are expected to receive the same treatment in the near future. The new Galaxy J series may arrive in the coming months as the Galaxy J5 (2017) has been spotted at the Wi-Fi Alliance. This certification is normally taken as an indication of an impending launch.
The Galaxy J5 (2017) model number SM-F530FM has been spotted at the Wi-Fi Alliance for the relevant certification. While the listing doesn't reveal any specifications of the device itself, it does mention that the handset was running on Android 6.0 Marshmallow. Whether or not that's going to be what it's powered by when it arrives remains to be seen, one would expect the company to at least ship the handset with Android 7.0 Nougat.
Samsung hasn't said anything about the new Galaxy J series as yet so it's not clear at this point in time when this handset is going to be released. However, we're bound to hear more about the Galaxy J5 (2017) in the weeks leading up to its release.
