How to fix this iPhone drama?

Within the past month, I've dropped my iPhone 3 times.
When I go on certain websites, sometimes my phone will close the window of the website I'm on and will revert back to my home screen.

What can I do about these things?

If you downloaded IOS 7 and have the 4 or 4s, your apps will start to close, your phone freezes, and it takes up alot of data. The only way is to get a new phone unless there's some way to uninstall IOS 7

You are too clumsy to own your own cell phone. Love, mom

Be more careful.

Try a hard reset press both your button and your lock button at the same time until your iphone powers off and powers back on. Which should resolve your problem if you still having problems then I would take your iphone to an Apple store.
