They will recharge you a restocking fee if you exchange for a different device, not if you exchange for another m8. And again they will NOT process a warranty claim within your 14 days. Try for yourself.. If someone is within their 14 days call the warranty department.. Make up some BS abut the phone being defective and you need a warranty replacement.. They will tell you they can't process one because you are within your 14 days return period. Also I learned if you had ordered it from the website the 14 days begins at the invoice date.. not the delivery date which is pure BS.. It should be from the delivery date.
