You're wrong, you will encounter many issues later on such as:
1)Samsung will remotely force your phone to be bricked so you had no choice but to return it
2)No more future updates from samsung
3)Banned note7 everywhere, unable to board the plane, etc

It's quite similar when you're insuring a 50k car and but you spend 20k to modify the car. Insurance does not compensate your 20k loss.

Let's get through with it, nobody want it to happen. It's one of a kind throughout the history of mobile phones. I myself also spend few hundreds buying casings to test. Now with the refund, the casing is actually kinda useless now as well.

You think you lost few hundreds, see those phone accessories seller who stock up few thousands of useless note7 cases/screen protectors.

Just dropped an email to Amazon customer service in the morning about my concern. Within an hour customer support agreed to refund back my money spent on note7 casings and SP. Damn good after sales

I think i will be taking the full refund, and use back my wife's xiaomi Mi3 first until something good comes up again. Still reasonably good phone to tahan haha. (I gave her my pre-order S7E so i can get the note7).
