Samsung Galaxy J4 (2018) live pictures published by regulatory agency

Today, the phone popped up at Taiwan's NCC certification website, which means Samsung plans to introduce the Galaxy J4 (2018) very soon. Along some of the phone's specs, NCC lists a handful of live pictures showing the entry-level handset.
We also know the phone will come with dual-SIM support and Android 8.0 Oreo on board. It's likely to feature a 3.5mm audio jack port as well, along with Bluetooth, Wi-Fi and LTE support.
It's also worth mentioning that the Taiwanese regulatory agency lists another Samsung mid-range smartphone, the Galaxy J6 (2018), which should be made official along with the Galaxy J4 (2018) model.
