Simple application that scans Wi-Fi networks.
This one for a reference: Get available wi-fi scan result in customized listview
Just put a ListView in a layout and add ACCESS/CHANGE_WIFI_STATE permissions into manifest.
The problem is that it works on my Samsung J3 (2016), but I don't know why it doesn't on my new Samsung M11. Has it something to do with Android versions? I have already returned a Realme C3 that was having same issues because I thought it was due to Mediatek SOC.
