I'm having several call quality problems with my android phones from Koodo. First, with my Nexus S, and then they remained the same with my Galaxy S2X (the phone they offered me to switch to, trying to eradicate the problems). People very often complain about how I sound on the phone (saying the call quality is awful), and I often lose contact for several seconds and then it comes back when I move around. It happens at different places (home, work, gym, etc.) since several months. The network has been reseted by a representative, and I changed the sim card twice. That being said, nothing has changed. Did that happen to any of you? What should I do? Thanks! Thomas, Quebec city.
