I had the same issue after bringing my P20 pro to a repair shop (replacement of the USB-C connector).[br]
-
My phone was while re-assembled properly.
To make it simply, the antenna is suppose to be maintained by (thus below) the USB-C connector. Mine was just above... Of course on the top of the antenna there is the common mass, that is supposed to make contact thanks to the screw and the USB-C connector ground aswell... [br]
[br]
Reassembling it is the right order fix my network issues. a mass not connected with an antenna... definitely make sense why i had no network anymore.[br]
[br]
Hope it can help some of you, a little mistake in the assembly can occurs quite quickly and whitout proper neutral
