My microphone doesn't work anymore and my capasitive buttons don't wor

I am having a similar issue with my microphone. Every call placed sounds like I am digitizing or loosing/gaining service(going in and out). Everything works great using speaker phone or headphones w/microphone. So I don't know what part to change or if it is even a hardware issue, after the latest update my recovery is gone along w/ features I liked. Any help would be greatly appreciated
