So today I noticed that when I go to make a call on my Note 3 the call goes through even though I cannot hear the dial tone or ringer and when I speak into the phone the person on the other end cannot here me. I cannot here them either. I when I receive a call from someone it is the same issue. My ringer will go off, but I cannot hear them and they cannot hear me after answering call. I am still able to access my 4g data, send texts and I am getting a strong signal (4-5 bars). When I went out my settings under mobile networks, then network mode it was set to global. I changed it to CDMA/LTE/EVDO but the problem still persists. Has anyone been experiencing this problem or know of any possible solutions. The timing for this is really horrible since I have a family member in another state who is currently hospitalized and this is preventing me from keeping up to date with them.
