Leah,
All I can say is YAHTZEE!
After returning two BRAND NEW Note 4's to my local Verizon store...
And after clearly pointing out the issue to my capable friends at my Verizon store...
They replaced BOTH Note 4's with BRAND NEW phones since i have a corp account and have 30 days on any equipment.
Well the SAME ISSUE happened again this morning (about a week later and just like before) and I was freaking out!
I HAD tried all of the other "fixes" suggested by all of our kind friends here that posted their fixes or thoughts regarding this problem, but with ZERO results.
Then, prior to going back to Verizon one more time and dumping Samsung altogether, I Googled my issue one more time and found myself here with all of you.
After scrolling down past all of the kind suggestions which I had already attempted, and which had all failed, I found myself at your post.
So after reading down a bit, I grabbed a "staple", unfolded it partially, inserted it in the very small hole next to the charging port on the bottom of my phone and hoped for the best.
I quickly rang up my wife and like I said earlier... YAHTZEE!
She could once again hear me 5 x 5.
However that obviously poses some inevitable questions:
1. Why or how did the mic "semi" fail in the first place (semi meaning only while in used without headset or Bluetooth devise)?
2. Why and how does that particular "fix" actually fix it?
3. And how long will it last?
Looking forward to hearing from you all in this regard.
Especially Leah who saven me a Factory reboot, set up, bla bla bla.
Thanks again Leah,
RANGER
