Just got a nexus 7 and I've noticed that the screen isn't as clear as I would have imagined. I can definitely see some sort of "fuzz" around everything. My galaxy nexus seems much more clear and crisp and also more vibrant in color. This is confusing to me because the nexus 7 should have a bit more resolution than the Galaxy nexus. Is this a defective screen or is it how its supposed to look?
