iPhone XS earspeaker not working after screen replacement

You could have damaged the solder joints on the cable. You can replace the the earpiece speaker. But my guess is a bad connection to the motherboard. Remove that connector and make sure all of the pins are straight and clean the connector with alcohol and a qtip and a soft brush. I actually had the same problem with xs max and it was the connection.

Yes that fixed the issue. I would first check the solder joints on the cable and earpiece speaker and then check the connection to the motherboard and make sure the pins aren't damaged and clean it and hopefully that will solve your problems.

I don’t know why they don’t offer this information on the countless amounts of inquiries that they have on this problem, but I’ve gone through all the motions myself and finally someone at the Apple Store was honest enough with me to tell me that they’ve started building the speakers into the screens, so basically bending your phone in the slightest fashion can screw up the speaker that you should be able to hear the other caller from. Apple is seriously slipping. They used to be top-notch. They used to build what was almost a bulletproof product and now they’re garbage. I’m actually dealing with this problem for the second time on a second phone and I’m thinking there won’t be a chance for a third time
