Feb 2020 iPhone XR speaker failure
The speaker on my Wife's iPhone XR malfunctioned. The phone rings and sounds alerts correctly but she could barely hear anyone when they called her. She had to put them on speaker to hear. Note, the ear buds sounded normally when used.
The nearest Apple store is 20 miles away, so I took it to the nearest authorized dealer, a Best Buy, who ran a hardware test on it and agreed the speaker was malfunctioning.
I did not realize it, but the speaker is integrated into the screen, so when it goes the screen must be replaced. The good news is that I had Apple Care, the Best Buy had the replacement screen, it took an hour to replace and because of Apple Care I was charged $30 dollars. I asked if this was a common issue, and the tech said yes. He also told me that without the Apple Care, the screen replacement would have been over $200 so having Apple Care paid off.
Note, this is the first iPhone I've needed a repair on just because something stopped working.
Was it under warranty ? Did you cause the damage?. If it is under warranty and you didn’t cause it the fact you had to replace the screen to get to the part wouldn’t matter. It should be covered under warranty
