Mine scratches so easily. It is no way GG2 on the back, a very 5cm drop caused a huge cut, and I also have 5 scratches over the devices. And before you start I have been taking better care of this phone then anything else in my life. My 4s did was much stronger and I dropped that at least once a week.
I know its unavoidable to occasionally drop things, but once a week?

Maybe get a Nokia 5110.
