Tracking error with white Nexus 4 is nothing to worry about says Google
A few people who had ordered the newly released white Nexus 4 had some tracking trouble recently, but according to Google, there's nothing to worry about. Still, it was an annoying issue for those affected. Apparently, Google sent the wrong tracking information to a number of customers, and in an effort to fix the problem, the tracking info listed the shipment as being returned to sender.
The thing is that none of the shipments are actually being returned, says Google. Google has been sending out emails to those effected, which states:
So, if you noticed something about your Nexus 4 being returned to sender, keep an eye out, because it may still be on your doorstep soon.
