My head has been wrecked today trying to find out why my phone kept making a noise every time I put it down on the table.
It turns out its the NFC (Near Field Communication) reading my contact-less debit card
I always put the phone down on my wallet or next to it and some sussed out the issue, well I think I have as when I switch off NFC the noise doesn't happen.
I only got the new card a day or two ago.
Wonder how much the phone has nicked from the card
