My phone keeps popping up the messages "Couldn't read NFC tag. Try again." and "No supported app for this NFC". What is an NFC tag? Why did this suddenly come up on everything I try to do? Why do I need a NFC tag (or app) to use my calendar? Thanks!!!
I get this same message when reading text messages or when I'm in my contacts list. This has become more than annoying. I shut off some notifications because they were annoying and I was getting too many of them. I can't be disturbed by notifications all day. I too would appreciate this getting fixed!
I would like to look into this for you. Let's look at a couple of things first.
Have you made sure your phone is up to date on its software?
Does it perform the same way under safe mode?
Have you tried clearing the cache partition on your phone?
