I am not sure if it is the watch but since I got the watch my phone calls keep cutting out for people on the other end, I can hear them fine but they cannot hear me for a second or two. Never had that problem till I got the watch. Oddly I can call them back on the watch and it does not cut out at all. Feel a bit like Dick Tracy talking into my phone but that is the only way the other end can hear me. I did just try to just take my watch off and that seemed to work and I spoke to my friend for about 40 minutes, then at the end of the conversation she could not hear me. So that might no have been the answer. I am at home and have never had a connection problem like this before.
