[Honor 7x] Ear Speaker Not Working

(No 7x option?)

Ear speaking isn’t working at all.

I’ve opened this phone several times now. I’ve replaced the battery, screen x2, and vibrate motor.

I cannot say when this first occurred, I don’t make/receive calls often and when I do it’s usually through earphones.

I have recently replaced the screen and noticed the issue a few days later. Since it is my own phone I was a little more careless and heavy-handed than I’d normally be and I tore the vibrate motor connector. I replaced it with a used and apparently genuine part from a Huawei Honor 9 Lite, which looks identical and works.

I have also just fitted a “BAQ” ear speaker replacement, and that doesn’t work either.

I don’t understand why it’s not working unless I’ve thrown something out? I’ve looked at teardowns and I don’t think so.

I’m waiting for a phone to charge to take pictures. But here’s some random sites with teardowns for reference:

It makes connections to the rear shell. Maybe it’s something to do with that?

I was thinking I’ve thrown something out with the old screen, but it doesn’t look like it.

The only thing I’ve tried is reseating the top section.
