I had the same issue. Probably an issue with the USB connector of the mobile phone.

I replaced the loading PCB with a new 7USD one.

Works perfectly except that the microphone doesn’t work in handsfree mode anymore.

For rework you need to solder the speaker from old PCB to new one. And you will need suitable sealing material, since the sealing of the original PCB can’t be removed.
