well i finally exchanged my phone for a bad battery. It was 5 series fyi and i got a 7 series. I did notice the little polka dots on the new 7, but honestly its barely noticable at 50% or lower brightness, no biggie for me. The battery life is much better. However i do notice a build quality issue on the black part on the back of the phone and where the speakers are its not really flush and there are gaps. My question is does the warranty cover build quality?
