I had a device with terrible miura, ps vita, I think. It was always annoying me. I think I had a warranty replacement with annoying muira because I like to watch things in the dark and seeing blotches in the black distracted me. It is much less of a problem on this S7. It bothers me in the sense I like to use tech longer, than corps want me to. Even if I hold onto this phone for 4 years, it probably won't be a big deal though my screen is probably on Mir than the average person. You can turn the over saturation off. I like sustainable, BIFL, stuff, so in that sense, I'm annoyed. I agree, I worry more about that battery. I charge this thing to 100 % 3 times daily.
