Have a rezound with the ICS update and I am not sure if the problem was there before update but it s there currently. Problem...If I am taking a call and another call comes in, I usually ignore it and keep talking. When this happens, the missed call is not logged. I do not see notification or a number. If I am reading a text message or sending one, I also do not get any calls. They just do not come through. The only way I know I had a missed one is if the caller left a voice mail message. I can get calls when I am not using the phone or text messaging. Anyone else having this problem or know of the fix? I do have the phone notification preview box checked under phone settings? Help would be great. actually if I am doing anything on my phone, I cannot get incoming calls It is annoying. FIXED!! I just cycled battery.
