1 phone struggles to find signal
So I recently repaired my screen on the iPhone 4 (yea people still used that thing) and when I turn it on it keeps searching for signal. A few seconds later it shows "No signal" and it start searching again. I tried resetting my network settings. I even tried to restore my device and surprisingly it goes through the setup process without problem (I heard people with the same problem can not get through the setup process because of the sim).
P.S. When I re-assemble the iPhone I mistakenly thought the gold ring next to the blue coil was the slot for the antenna connector. I didn't press it with huge force though. Is there a possibility that they are broken?
Take a picture of the antenna connector that is attached to the loudspeaker (bottom speaker) and the connection on the logic board as well which is located left of the battery connector.
