I get this error message many times a day. "The process com.sec.android.app.twlauncher has stopped unexpectedly. Please try again." I hit force close and I am on my merry way. Until the next time. Which can be right away or an hour later. Any ideas about how to address this. It looks like an OS issue.
Honestly this is the only issue ZI have with the phone. I feel lucky.
Apparently it's the task launcher that is corrupted you either have to do a complete factory reset or try this optional route which I am not sure about http://menardconnect.com/2011/10/19/free-android-fix-process-com-sec-android-app-twlauncher-error-without-factory-reset/
