Hi HYC. If you are a bit curious, attached is a new logcat run via the awesome getlogs app. (Renamed data.zip) The call comes in at 11:51. I don't understand much, but real quick, here are a few ring related snippets.
(Again, I'm just posting without any expectations of anything at all in in the form of support. This is just for hyc's knowledge.)
