Matrix: this issueus your talking about is usualy caused by an app that tries to manage a data connection. Most of the weather apps will do this if you allow them to manage your connection. Turn this off (their mangement of the data connection) and it should stop. It has something to do with it going to suspend and not checking, then when it awakes from a call it imediatly tries to connect and causes the un-resoncive phone app. I had this with sbsh weather and it was a known issue back in the aku 2 days. I would not have to reset though as after the call ended, I would be able to get back into the phone app. It was frustrationg until I found out what caused it. Also there are no other users reporting an issue like this, other than those with the data issue (weather apps). If no weather apps, you may want to check your 3rd party apps as one odf then may be comflicting or having a similar issue. Just an FYI
