I did remove it before. u can wiggle it a little bit then pull it up, it won't break, and there's no glue at all.

I'm sure if you kept looking at the cell phone repair shops, or cell phone repair parts you'll find the earpiece part. The iPhone 8 is very popular. I found mine for like $4-$5 in Saudi Arabia. otherwise you can look at amazon or eBay. good luck.

I’ve broken the connector of the speaker (on the logic board) by installing it in the wrong way.

Now, I ordered the connector from aliexpress, and have to do some micro soldering and hopefully it’ll work.

Be careful guys
