Weak Wifi, Bluetooth and Cellular after housing replacement?

Hi,

I recently bought a metal housing from Aliexpress to replace as my housing is badly damaged. Followed an instruction guide on youtube and everything was assembled properly.

However, just when I thought I was finished, I tried inserting my sim card in and the cellular was really bad, it was at 1 bar. Then, I tried connecting to the wifi at my house it didn't detect any wifi around my neighbourhood or my own router , I literally had to stand next to my router to use the wifi and same goes for my bluetooth it didnt work unless I stand next to the bluetooth device too.

I'm really devasted and my warranty with apple has ended, did some research and bought the cellular and wifi antenna online to replace it but it still didn't work, any suggestion or opinions are appreciated thank you in advance!

Show us a pic of the inside of the case, especially the screw holes.

The top antennas are the bezel itself, if the screw holes have paint on them and are not conductive, you will not get any signal.

As I suspect this case has not been properly machined. The internal surface and screw holes were not sanded down to conduct electricity. So the reception will be poor.

Remove everything from the board, sand every screw hole and contact surfaces, make sure the internal looks just like the original case.

Hi, thanks for you helpful reply, I'm going to purchase some sand paper later but do you have a picture or video for reference on where to sand it ?

You can check the ifixit teardown. They disassembled a gold one, the internal screw holes and conductive surfaces are silver, while the painted surfaces are gold, it's easy to tell.

Also check the disassembly guide for EVERY screw, clip and contact washer. Many of them are related to signal reception.

Done sanding and put everything back together but the connection is still very weak for wifi, cellular and Bluetooth, I don't know what's wrong with my phone :(
