Either the QC at Apple a.k.a Foxcon sucks that much that nearly every device (none out of 7 without an issue) is defective, or the devices he has got as exchange are out of a stock of already exchanged restocked and in some kind defective iPts (statistically that would make more sense).
Another guy who posted here some days ago had to exchange 5 iPts and his 6th exchange was finally without an issue. That is a chance of 16,7% ! That QC sucks a big time and Apple needs to know this and I'm sure they know, even if the geniuses are advised to claim that they never heard of that problem before. So people need to keep exchanging to give Apple a negative feedback. So that they change something about it!
