The screen or the back panel is broken
- If the screen or back panel is broken, contact a Sony Mobile contact center for further advice and guidance. A broken screen or back panel is usually not covered by the warranty, but we can still help you to handle the issue. Before determining whether the warranty covers a broken screen or back panel, a service technician must examine your device.  Go to Product Repair. 
- Remember the third condition of the Limited Warranty for your device: 3. This warranty does not cover any failure of the Product due to: Normal wear and tear.

- Before handing the device over for service, back up all your data, if possible, to avoid losing personal content. Data on the device is deleted during the service procedure.
