Here is the answer if you are having issues with the Galaxy Nexus (as I did, straight out of the box). Once you have it, unless you are able to directly return/exchange the defective product...then you have to send it to Samsung for a Warranty Repair. They send you a UPS label, and it takes (apparently) 5-7 days. I will attach a photo of what my screen looked like when I received the phone -- a large permanent purple dot is present on all screens.....
Q: What do I do if my Galaxy Nexus is broken?
Google is not providing replacements for broken or defective Galaxy Nexus devices. If your phone has a manufacturing defect, it is covered by a one year warranty. Please contact the Galaxy Nexus US Dedicated Line at 1-855-392-6398. Additional warranty information is provided in the retail box for your phone. Please note that because Samsung US (STA) does not carry this SKU in the US and does not have parts to perform repair, if an HSPA device is submitted for an non-warranty return (for example if the phone is dropped and the screen cracks), the cost will be for a full replacement device ($499).
You should factory reset the device if you can before sending to Samsung.
