Today I tried an USB-C Ethernet adapter on my Xperia XA2 Ultra.
It works and Ethernet interface is up.
But … in native browser, few tabs work normally and others ask for Wifi or 4G. Android apps ask for wifi (no internet detected).
It seems that the flag « network available » is managed only on wifi and 4G. What if this flag can be managed on ethernet interface too ?
(I tried HDMI output too as the pinephone, but it doesn’t work)
