I did the Google security update in March and it changed my Play Store status from device certified to uncertified. I was previously using contactless payment but it says my device is insecure. I have spoken to Google and Samsung, as well as submitting an error report on this app, but I've got nowhere. Has anyone had this issue?
I have a feeling I might have been miss-sold my phone. It was sold as a UK edition on Amazon but reading the reviews, a few people have logged the same issues with contactless payment. Do you know where I can check my IMEI to see country of origin?
