My Galaxy Note 2 has a problem recieving calls. Quite often the phone doesn't ring and it goes right to voicemail. For instance, my wife tried about 30 times over an hour tonight to reach me, and the calls went to voicemail, after silence for a while. It never rang once at my end. This has been happening a lot when people call me. I have heard that this might be an issue with voice over LTE, and am not sure if this is the problem (might only be with US Carriers and not here in Canada). If that is the case, I am not sure how to disable it. Any suggestions/solutions?
