nfc not working what should I do

I’m sorry your NFC feature is not working on your Mi 9T Pro. There are some possible reasons and solutions for this issue. Here are some steps you can try:

• Enable NFC on your phone. You can check this by going to Settings > Connection & Sharing > NFC and turning it on.
• Unlock your phone when using NFC. Some apps may require you to authenticate with your fingerprint, PIN, or pattern before using NFC.
• Bring your phone close to the other NFC device. NFC works best when the devices are within 10 cm of each other and aligned properly.
• Remove any phone case or cover that may interfere with NFC. Some materials, such as metal, may block the NFC antenna on your phone.
• Choose a default payment service for NFC payments. If you have multiple NFC payment apps on your phone, such as Mi Pay or Google Pay, you need to select one of them as your default payment service in the NFC settings. You can do this by going to Settings > Connection & Sharing > NFC > Contactless payments and choosing the app you want to use.
• Clear the cache of the NFC app. Sometimes, the temporary data stored in the cache memory may cause problems with the NFC feature. You can clear the cache of the NFC app by going to Settings > Apps > Manage apps > NFC > Clear cache.
• Update the software of your phone. Some software updates may include bug fixes or improvements for the NFC feature. You can check for updates by going to Settings > About phone > System update and tapping Check for updates.
• Try some other troubleshooting methods. If none of the above steps works, you can try more advanced troubleshooting methods, such as resetting app preferences, booting into safe mode, wiping the cache partition, performing a network reset, or performing a factory reset. However, these methods may have some side effects, such as deleting your data or changing your settings. Therefore, you should only try them as a last resort and after backing up your data.
