iPhone 5S speaker/mic issue

[mike4realz]

once in a while, the mic on my phone just cuts off during a conversation. i can hear the caller perfectly fine but the caller is unable to hear me.

also, when i play voicemail messages using the speaker, i can barely hear it even tho i have the speaker volume at max. i have to reopen the phone app just to clear out that bug.

anyone having this type of issue with the iPhone 5S speaker/mic? this only happens once in a while

Have u tired resetting the phone? Hold the power + home button at the same time until it's off and release it after the apple logo appear? If yes, try to restore your phone and see if the problem still persist?

But from my opinion, i guess that u have a faulty speaker and might probably need to replace. Try bringing it to the Apple store and let them have a look at it.
