I think there's a bug in Android where some Alicia Han appears to be calling. This happens some times if you hang up on someone calling you, or you have a missed call. The name appears in the instant before the correct name of the caller appears on the phone. To be specific: In the interim between the phone screen turns on and the content is loaded on the screen.
All relevant hits I get on the subject is this tweet. So I'm not crazy!
Have any of you seen this, and do you know what happens / who Alicia Han is? This has happened haphazardly since I got my HTC Sensation XE a year ago.
Edit: I think the problem might be that there is a standard Label text for a Person entry (such as the ones in the Persons list) that is set to 'Alicia Han' and the label text is replaced when the Person information is fully loaded.
bug is reproducible (at least for me) by hanging up an incoming call. The name Alicia Han appears for a few milliseconds before the real name is loaded.
