But the funny thing is that most nokia care guys actually advise against putting screen guards.
I bought my phone online and didn't come with a screen guard. I went to the nearest nokia care to get one.
The guys over there told me u don't need a screen guard as ur phone got gorilla glass. The fact is 620 doesn't have gorilla glass and it took me a while to convince them to actually put a screen guard on it. If that's the case with my non GG 620 then I bet it will be even harder to convince them to put screen guard on a GG3 630
