For transparency – I am not the first owner. I recently bought the phone from a nice chap on Facebook marketplace. I have the proof of original purchase, which I’ll be happy to forward to the buyer. The UK warranty is until 10/06/22 for the device, headphones, charger or cable. The original owner has previously said he’d be happy to help in case of warranty issues and of course I’ll be happy to help too. (OP amended)

Kind regards
