Had my new Samsung for nearly a week, and now I find that it can be remotely wiped (including disabling the SIM card), by SMS, viewing a QR code, visiting a website, or reading a NFC tag! Yikes!

There are quick and simple fixes, so if you know anyone with a Samsung Galaxy phone (most models), give them a heads-up.

Here's a test page to check if your phone is vulnerable:
