The funny thing about this is that it probably didn't do them any good at all. iOS users prioritize UX over benchmarks. WP8 users work for Microsoft. So this is just competitive against other Android devices, for the narrow segment of people who look at benchmarks... Who were probably all going to buy Samsung anyway. Why risk the PR black eye?
Did it sell even one more phone? We've got a lot of highly technical Android users here... did any of you change a purchasing decision based on these benchmarks?
