@cliff01: If you're referring to scanning QR codes from your phone's display, then I suppose that this would depend on the extent of the damage. The best course of action would be to arrange for an engineer to inspect and repair the device to bring it back to warranty specifications, however please be aware that this would be a chargeable service. If you're based in the UK or Ireland then please reach out to our Help Desk via the link below, and an advisor will be able to make the necessary arrangements for you.
Alternatively, please visit your nearest Experience Store or Support Centre to arrange the inspection yourself. To find your nearest one, please follow the link below, click on Mobile Device and enter your post code. Please be aware that our stores and Support Centres are currently operating on an appointment only basis, therefore please click on the results of your search to the left of the map, scroll down and select 'Reserve' in order to proceed with the booking process.
