Nope! I use one of those things called... hang on, this is a hard word to remember... 'case'...? Not sure if it's spelled like that. It's a magical thing that protects your phone and makes it not break. Jokes aside, I don't understand how a screen would break from hitting a table corner even without a case. The impact will be softened by your body and it shouldn't be enough pressure on the screen to crack it, right?
