Had my note 5 since August 21. I put on a glass screen protector and no case. Used it very gently, didn't drop it once. To my dismay, while cleaning the phone this morning, I noticed a crack across the entire length of the back. I have no idea how or when this happened.Really disappointed as this is a really great phone. I don't think I'll be getting a replacement, probably just go back to my Note 4.
