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?

这是一个好问题吗？

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