My wife has the Optimus Chat and the lock screen timeout is 3 or 4 seconds evn though the screen setting is set to one minute. My Galaxy SIIX has a setting for lock screen time out, but I don't see that setting in the Chat. Can someone help me please? EDIT: I just looked at my Galaxy SIIX and realized that I solved my lock screen timout issue with WidgetLocker. It has an overide setting for this purpose. I have not found a default Android setting, so if someone knows of a default setting, please let me know. Thank you!
