Does an iPhone 4 scratch easily?

In August 2012 I bought an iPhone 4 (yes, I know, I'm very late) but anyway, ever since I got it, it's always been in a case and had screen protectors, both on the screen and on the back side of the phone when I use bumpers. But after a certain period of time the screen protectors get really dirty and you can't really use the touch screen properly because of it and it's really annoying to always have to change the screen protectors. So I was wondering… Does the phone scratch easily? I would like to just take the screen protectors off and not worry about scratches that much… I've never dropped my phone to the ground while holding it, I take really good care of it so there wouldn't be any scratches like that but I've heard people say it scratches Really easily and I can't stand scratches on my phone so what do you guys think I should do?

Yes, it does really easily. There are some screen protectors that you can use it with, they have high prices though, go to mobile phones store and tell them to put the screen protector for you they will clean it the iphone's screen so it won't have any dirt on it.
Hope this helps.

Yes super easy. Its made out of glass and it breaks easy too. Its why you need a full protection cover on it.

I've had an iPhone 5 since they were first issued & have yet to get a scratch on it. That's without a screen protector. I don't see why they would make the iphone4 screens any differently.

No is not because is made from gorilla glass and this is what the apple are proudly say that their phones only a diamond can scratch them

here is a demo prove
