My s9+ screen broke in under a week from being in my front pocket whilst getting into my car, a task I have done thousands of times with my trusty s8+.
S9+ has Full hard case genuine Samsung with flip cover.
They told me I had been abusing my device that's less than a week old, insisted I was lying to them and generally poor customer service for something that is a genuine manfacturing defect on a device that is not fit for purpose under the nz CGA.
