Hi, I'm looking for some help here with an issue my wife and I both have with our phones. My wife and I are the Proud owners of the Samsung Galaxy S2 phones. I have the Data plan and she does not. In the past 2 months or maybe since the begining of Sept. we both are haiving the same thing happen. When making or receiving calls (both in Wifi and T-mobile networks) we can't hear the person on the other end. We have to hang up and call them back (with success) on the cell or house phone. They let us know, they can hear us fine but we can't hear them. This happens on all Landlines and Cell lines that we call or get call to our cell. I have contacted T-Mobile and they can't find anything on their end. I have done a Factory Reset on Mine and it still happens. 2 weeks ago, some weird things were happening to both our phones on the same day. with this being one of them. I plugged my phone into Samsung Kies and there was a Device Firmware update. So I updated to the ANDROID VERSION: 4.0.4 BASEBAND: T989UVLH1, and after update, I Reset phone to Factory Reset Settings and that seemed to help with alot of the freezing we had. But the phone call issues still happen. I also have noticed, that now we periodically loose the Network connection. I can be sitting on the couch with a 100% Wifi coverage and not move an inch. I would dop my connection and the call and still have wifi coverage.I will also contact Samsung to see if it has something to do with any patches or updates. But for now, I am lost for ideas. I was wondering if anyone else is having a similar issue or the same issue..or id anyone has a fix for this?
