I got the newest update yesterday and noticed this morning that on the lock screen there is a warning saying "The SIM card is missing or not readable. Please insert a SIM." which then chnages to "Vodafone UK. No SIM card." and then back to the first message.
Despite this message the phone works fine and makes calls so the SIM card is clearly not missing or not readable. Why is the phone showing this message?
