Samsung has sent out a new collection of bug and security fixes for some of its latest mobile phones.

This time, around 30 vulnerabilities have been identified and patched. As usual, users are encouraged to install the update as soon as possible to keep their devices secure. If you don’t, you’re leaving your device potentially exposed to viruses and malware.

Currently, this November update is available for the following devices:

If you own any of these devices, head to Settings > Software update > Download and install. Check to see if an update appears that’s dated November. If older versions appear, download and install them first.

However, if you have one of these devices or another Samsung Galaxy phone, you might be waiting a little while longer. Don’t worry, all compatible devices are expected to get the November update soon.

Even if you have a different Android phone, you’ll want to update it now to protect against security attacks.
