In the last couple weeks I have started experiencing echo on my phone. Everything I say comes back to me and the other end can't hear anything. Sometimes it will take 3 or 4 calls before it starts working again. Tried figuring out if it's a specific area (which it appeared to be) but now it's worse and happening all over the place. Haven't seen/installed any updates lately, anyone else experiencing this? Next step is to stop by or call Sprint this week. Phone I believe is a version 1 f(got it on launch day).
