[T-Mobile Samsung Galaxy S II SGH-T989] Splaktar:
OK, I've managed to capture some logcats for this unable to open apps issue that some people have been seeing for weeks.

In this case, surfline.android is the app that I am trying to open. The icon highlights but the app never opens. I can open up currently running apps screen via long press on Home. I can open up the notification bar. I can scroll through home screens and open up the app drawer. But most apps won't open when tapped on.

Seeing a ton of these GBA errors. Not sure what those are related to.

Also saw a lot of errors related to being unable to connect to WiFi Calling (ports blocked here at work), but this one seems to be something different.
