Mystery Samsung Galaxy phone spotted passing through the Wi-Fi Alliance
The mystery Galaxy phone received its Wi-Fi certification
The device in question was running Android 8.0 Oreo when it got its certification. As to what device it is, there are quite a few possibilities.
The Galaxy Prime on T-Mobile and MetroPCS had model numbers that began with SM-J727, but the Galaxy J7 Prime was already refreshed in 2018. The Galaxy J7 Perx was released in August 2017 with the model number SM-J727P, so our mystery phone could be its successor.
Samsung usually releases quite a few variants of their Galaxy J series each year, so this device could really be anything. All we know is that it has passed its Wi-Fi certification and is moving onto the next stages prior to release.
