Samsung has started pushing out a new update to its Galaxy Note5 smartphone. Weighing in at around 295MB and currently hitting units in India, the update brings along Android security fixes for the month of December. It isn't yet known what other changes (if at all) are included in the update. Given that the update has just started rolling out, it may take some time to hit your device. Meanwhile, if you feel impatient, you can manually check for it by heading to your phone's Settings menu. Via
