Why do iPhone screen crack so easily?

I use to have the iPhone 4S now I have SG4. When I have the iPhone the screen is easily cracked especially when screen facing down. But when my SG4 dropped on the ground facing down it is not cracked, not a tiny bit. So what makes the iPhone screen so easily cracked?

Need an advice! My iphone got wet but still works fine?

I spilled my water bottle on my backpack about 2 hours. I just noticed it when I opened my backpack and I saw my iphone 4s got wet, it wasn't submerged it's just wet. It still works fine, quickly I turned it off and haven't yet checked anything because I was shocked. Now that I got home I put it on a bag of rice. What to do after this? How long should I put this? I'm afraid if I turn it on before the phone completely dries it will get a problem.

What was the point in removing flappy bird from the App Store?

I honestly don't see what the point was. It was a good game and I'm sure the owner was making a ton of money off it. I know that it is addictive but it isn't as if people are loosing their jobs over it because they can't stop playing flappy bird. There have been other addictive iPhone/android games in the past such as temple run or candy crush, so it isn't as if a new gaming craze hasn't happened before. What do you think the owners reasons were for removing the game?

IPhone 5 Dropped on Floor and Broke (NOT SCREEN)?

My iPhone 5 slipped from my hand and fell on the floor, I thought it was normal because I've dropped it, like, a million times before, but when I picked it up, its won't work anymore.
I've tried powering it on, but black screen, nothing.
I was thinking of going to a Apple store near me to fix it up, or can I fix it myself?
