Why does my phone have issues connecting to anything?

My phone has slowly been degrading in its ability to connect to things. It started with my calls dropping and my phone randomly losing service. Then Bluetooth devices had to be closer than usual to stay connected to it. Then the GPS stopped working entirely— neither apple maps, Google maps, not Waze knows where I am at any time. Now I have returned home from college. I used to be able to connect to the wifi in my home from my room, especially from my bed. Now I cannot connect to it at all in my room. I have to be much closer to the router than usual for it to connect and stay connected. Often it doesn't even come up as an option. If it has a week signal, and I try to connect, it will tell me I have the wrong password. If I re enter the password, it tells me that it can't connect to the wifi.

Chances are the Wi-Fi / GPS antenna has gotten damaged from the phone being dropped numerous times. I recommend replacing it and seeing how it goes.

Before ordering and replacing that part I would open up the phone and inspect the top of the board for any signs of liquid damage or corrosion. These are evident by white marks (appears when moisture is in contact with metal contacts) appearing on the board along with sometimes black marks which indicate burns.

Check if the bottom right antenna cable is plugged in to the board, this comes from the charging port assembly area. Also if the housing is bent / cracked around the corners this will degrade 3G / 4G antenna signal.

When the phone loses service, go into the dialer and dial *#06#. If nothing is displayed this indicates the phone has a baseband chip fault (one of the connection pads usually get loose under that chip which causes an intermittent connection to that chip).

I have bought a couple of defect iPhone 6 with the issue you’re describing. iPhone 6 Logic Board Antenna Flex Cable is the part that needs to be replaced to fix the wi-fi part probably. From my experience the connectors gets loose from the flex itself which makes the connection really weak, after i have removed that flex sometimes those pins completely goes off from the antenna flex and get stuck in the moterboard, which shouldn’t happen by just disconnecting. Not sure if they wear out over time or if it’s caused by dropping the phone though.

The losing service part might be caused by a bad antenna from the charging dock flex, cant find product on that part here on ifixit though.


Since there’s so much going on there could also be problems with some IC on the PCB and i’m not really experienced when it comes to microsoldering or motherboard issues, so cant really help you out if that’s the case.
