Hey so I dropped my phone and now it receives no signal WiFi is fine so from what I can tell it’s the attena that’s gone screen is fine also I cannot see any guides only that show were this is or how to replace it any help would be good thanks

The wifi attennas are part of the metal frame this may be a board level issue you can replace the frame of the phone and that may fix your issue if not it would be related to the board.

@richens check with the Samsung troubleshooting guide:

the importance on this is that you properly identify your model. Let us know what SM-920 it is since there are differences on the board or post some images of your board with your question. that will allow us to see what you see. Use this guide for that.

Can you check if the IMEI number is still displayed under settings > general > about phone > status?
