I got my phone in November '14 and a few weeks after I started getting complaints that people couldn't hear me. I tried everything on the internet, like clearing the cache, resetting, and blowing out the microphone with compressed air. Nothing worked so I called support and while they were nice, they didn't really help me. They claimed that they could hear me fine. I've been trying to deal with it using speakerphone or headphones, but it's really frustrating. I upgraded to Lollipop last week, but it isn't any better. Any other help out there? I have the total protection, can I get it replaced? I know this is a defect because the phone hasn't been damaged, I haven't dropped it or gotten it wet. Oh, the screen also gets really hot when I'm using it. I don't know if that's related or not. Thanks for your suggestions!
