Samsung SCH-U740 Alias

HAS ANY NOTICED THAT WITH THE ALIAS SOFTWARE (NOT THE U740)THERE'S A PROBLEM WITH THE AUTO VIEW (SEEING THE TEXT MESSAGE ON THE FRONT SCREEN). WHEN SET TO AUTO VIEW & THE PHONE CLOSED, IF YOU RECEIVE A TEXT MESSAGE THE PHONE WILL NOT RING OR VIBRATE. I'VE TRIED MORE THAN ONE ALIAS & THEY ALL HAVE THIS PROBLEM. I NEVER HAD THIS PROBLEM ON MY SCH-U740. PLEASE LET ME KNOW IF ANYONE HAS NOTICED THIS & ANY POSSIBLE SOLUTIONS.
