Samsung just announced that they will probably be installing a new chip into their devices that will disable the use of 3rd party hardware. These include batteries and chargers as well as other less expensive 3rd party devices. You will have to buy your devices from Samsung. I have never bought a Samsung phone and this pretty much seals the deal for me that I never will. I recently purchased my HTC One and I am extremely happy with it. My old phone was an HTC Hero. No Samsungs for me.
