Just wait until your replacement is just as bad.
And then the one after that.
Then you give up and just want a refund but you have to constantly chase up the shipping documents/envelope.
Then the waiting for them to acknowledge receipt of the return.
Then waiting weeks for them to actually refund the money into your account.
After the debacle I had with my Nexus 7 I promised I wouldn't bother buying a device direct from Google again. The above doesn't factor in the fact that they lost one of my replacements, tried to disable the device I was currently using instead of the lost replacement and then tried to say I wasn't entitled to a refund because I had then gone out of their "refund window".
Unfortunately, I broke that promise with both the Nexus 4 and 10. 4 is fine thankfully but the 10 was sent back over a week ago and I'm still waiting for them to acknowledge the return.
