Cortana listening and speaker phone not working.

[wp8-1]

My phone no longer seems to pick up my voice on speaker phone or when I try to tell Cortana to do something. It works dine when in a call without speaker phone. This has been going on for about a week or less. I have soft reset it and everything. Any help? Idk if this is related, but my phone overheated recently. Everything else works great. it's a 925 btw.

Are you on the Preview for Developers?

​Seems odd behavior and I would not assume the overheat would cause such an issue...
