I have a Nikon 5300 DSLR and an Android 7.1.2 device (LineageOS).
I want to use Nikon's official WirelessMobileUtility app to browse/transfer pictures and take pictures without touching the camera.
Problem: The connection never works, even after trying dozens of times. In the manual (and YouTube tutorials) the steps are so easy (enable WiFi on the camera, connect to that WiFi from the phone, start app) yet the app never manages to connect. Many recent Play Store reviews mention this problem.
How to make the connection succeed?
Important: This question is only for Android 7.1.2 and above
