I bought me a couple of these. Initially I thought they replace the battery cover, but it snaps onto the rear to provide some additional protection. The camera lens is now recessed which is great to prevent scratches.
They have a brushed aluminum look and look fantastic on the phone.
I want the phone to have a heavy more premium feel, and is there a way to do this? Such as replacing the battery cover or something with a heavier one?
I don't understand. Samsung, and every other phone manufacturer, invest piles of money to trim every single gram and make the phones as light as possible. To me, light = premium! Why do you think that heavy = premium?
Having a certain weight and materials can make the phone feel premium. Lightweight nor heavyweight really determines this. Just the build quality and materials. And it's no secret that the "flimsy" plastic used on this phone makes it feel less premium than other devices. Not that it's a bad thing or it's not but it's the impression you get. You can read any review of the phone and they would mention how it doesn't have a premium feel when compared to some devices like the iPhone or htc one x. Not that I agree but if it doesn't feel premium to someone then that's how it is to them. Just like a device can look nice to you but ugly to someone else.
