A lot of interesting evidence is being brought to the public’s eye in the ongoing Apple vs. Samsung court case. Nothing is more interesting, however, than a study conducted in 2010 by Apple. It wanted to find out why people were buying Android phones over iPhones. The results are actually pretty surprising.

CNET got their hands on an Apple study that was passed around internally in 2011. It was used by Samsung as evidence in their ongoing case against Apple. Apple claims that Samsung copies their devices while needlessly confusing the consumer. Apple’s own study says otherwise.

The study found that 48 percent of those surveyed bought an Android phone to stick with their current carrier. Remember in 2010, the iPhone was still only available at AT&T. Switching to AT&T from any other carrier for just an iPhone seems like a silly proposition except for the most hardcore of Apple fan.

The other reasons are just as damning for Apple’s claim that customers don’t know the difference between the iPhone and Samsung’s phones. The study found that 36 percent of Android buyers went with the brand because they trusted Google. Another 30 percent just preferred the larger screen. Other reasons vary from preference for the Android Market to a desire for turn-by-turn navigation.

Apple has addressed many of these causes for defection over the last few years. The iPhone is now available on pretty much every carrier. They are also introducing turn-by-turn navigation with iOS 6. It would be interesting to see if the reasons for people choosing Android over iPhone are the same today as they were in 2010.

It should also be noted that this study lumps Android phones into a single unit. Those questioned may not necessarily represent those who bought Samsung phones. It would be safe to assume that at least a few were Samsung phone owners since the company made it a point to release devices with bigger screens than the competition.

Expect more fascinating documents like this one as the trial continues. Samsung and Apple undoubtedly have a lot left up their sleeves in this legal battle. Neither of them are going to get out of this unscathed.
