Freezes every text or call

This is my first review for any app and I just REALLY love Terraria but there is this bug that is starting to get annoying,well first I have lots of friends to text me and anytime they do well Im playing Terraria it freezes making me restart the app. I love the game but I only have a problem with this bug, please fix it. Oh and a little suggestion, can you add a creative mode, Id love to see which weapons and armor I need to beat certain bosses, but please fix this bug, thank you
