Poor cellular connection
I am on O2. My iPhone 8 plus has shown only 2 bars when my neighbour has 4 bars and is less than 50 yards from me. I have just bought another iPhone 8 plus and this gives me unto 4 bars in the same location. It is also picking up a CarPlay connection within seconds whereas the old phone struggled. My question is can the cellular bit of the hardware fail? All is there a remedy for restoration.
