IPhone 11 Speaker Issues

[swm59nj]

       I have an IPhone 11 purchased at an Apple Store in Bangkok.  I have had it for about 2 years and a couple of months.  About a year ago the speaker near the camera stopped working.  The Apple store replaced it but it was off warranty.  Now the left speaker on the bottom of the phone has stopped working. I called Apple Support and went through trouble shooting.  I also used a small fine brush and made sure no dirt is blocking it. I now need to bring the phone in.  The support person thinks that speaker needs to be replaced.

       Has anyone have had issues with the IPhone 11 speakers failing?  In the the past I owned an IPhone 5 and 7.  Each for about three or four years. I never had any type of hardware issues with those phones.
