Samsung has started pushing out a new update to its Galaxy A5 (2016) smartphone. Currently rolling out in Europe and weighing in at over 20MB, the update brings along Android security patch for the month of October.
In addition, the change-log for the update reveals that fix for a critical security flaw is also included, although details aren't mentioned.
As is usually the case with OTA roll outs, it may take time for the update to hit your device. Meanwhile, if you feel impatient, you can manually check for the update by heading to your handset's Settings menu.
