Additionally, a warning may be generated if the amount of physical bend exceeds the threshold. In one example, one or more values representing the amount of physical bend are stored to a nonvolatile memory on the device and retrieved in accordance with one or more of a diagnostic push event or a diagnostic pull event. ## Claims ### Claim 1 An electronic device comprising: a flexible display;
