When I talk on my phone maybe after 20 minutes or so, my call gets interrupted. Its not like I get disconnected its like the phone call just stops.

Im on my Wi Fi and my connection is UMA

Is there a reason for this? How can I fix it, its annoying. Never had this problem with my 8320.

Could be due to losing the UMA signal and the phone not transitioning smoothly enough to EDGE network. In your Wi-Fi options, edit the Wi-Fi profiles that you use and make sure that 'Allow inter-access point handover' is CHECKED. Saw this in another forum, sounds like it would work for you as well.

thanks so much, will check it out!
