Samsung Galaxy S4 WiFi broken

Hi,

I've been repairing an S4 recently, it was smashed and is now riddled with problems.

I've just bought a replacement sim card reader as the previous did not work.

the wifi/bluetooth do not work but I bought a replacement antenna, I am wondering if this is the cause?

also the external speaker does not work

does anybody know why the external speaker wouldn't work?

Answer this question I have this problem too

Is this a good question?

Have you checked the spring contacts on the usb pcb that connect to the speaker, they may be squashed
