siri and speaker phone wont work on iphone 5

I am having the same issue. I thought it was the speaker and had it replaced under warranty and it still does not work. However, I tried with my head with my headphones and it does work. If anyone has any solutions/advise please assist.

thank you,

The iPhone 5 is still under warranty. If restoring as a NEW device doesn't solve your problem, bring your phone to Apple for replacement.

Hi gdgmacguy,

I was wondering if things in Korea work differently, i took the phone to an authorized provider and they decided to fix the phone versus exchanging for a new one. The problem with the speaker persisted and the technician agreed.

thank you,
