The contact list may not shows immediately sometimes. You may need to try 5~10 times to reproduce it. 1. Launch SMS app 2. Click on "+" button on the top right 3. Wait for a black panel appears from the right 4. Black panel remains, contact list not shown Expected: Black panel is replaced by contact list. Actual: Black panel remains, contact list not shown immediately. Contact list may appear if you wait long enough (20 sec). And if you touch the screen the contact list will shows immediately. I can only reproduce this bug on contact app, not other apps.
this is an old bug, I think it can be closed
