Samsung rolled the Android Pie update for the Galaxy J7 Pro last week, and given the similarities between the J7 Pro and J7 (2017), we were expecting the latter to get Pie soon as well. That turned out correct as the Galaxy J7 (2017) has started receiving the latest version of Android.
The Android Pie build carries version number J730FXXU4CSF1 and comes with One UI 1.1. The firmware includes features like Night Mode, navigation gestures, and Digital Wellbeing. It also comes with the May 2019 security patch.
The update is currently rolling out over-the-air in Spain but should expand to other countries soon if all goes smoothly.
