Help to find a WI-FI antenna in a smartphone (Jiayu G2)

Question

Iron

In general, there is something with the antenna in Jiayu G2 - the connection suddenly disappeared, there is only 1-2 m from the router. Software-firmware dances with a tambourine do not give anything, so the conclusion is in the hardware. I want to try to replace it, pull it, etc., but I don’t want to unstick everything by typing.
Please help me find her? I am enclosing several photos of its insides from the Internet, on the first, the available antennas are marked with numbers.

Answer 3

Thank you, this is it!
It turned out that it was not the antenna that mattered - without it there was no reception at all, but with it or substitutes - as it was, i.e. quite weak.
I distorted the entire board, and did not find where the trouble with wifi came from ((
