Each of these updates brings only the newest security patch. The December security patch, as detailed by Samsung at the beginning of the month, fixes six critical vulnerabilities in the Android OS. Fixes for 13 vulnerabilities that affect only Samsung's software are included as well. One of these vulnerabilities could allow a connection to a new Bluetooth device on a locked device, while another granted access to the home screen wallpaper when brightness levels were adjusted without unlocking a device.
If you own any of the phones mentioned above, you can download the December update over the air from the Settings » Software update menu. We also have the latest firmware for these devices in our firmware archive, which you can use to manually update your phone using a Windows PC.
