A new update has started hitting the Samsung Galaxy A5 (2016) and A7 (2016). Weighing in at just under 40MB and currently hitting units in India, it’s a security update that brings Android fixes for the month of June.
Given the size, it’s reasonable to assume that no major feature is included the in the update, although the change-log does say that a “critical security vulnerability” has been patched.
Given that it’s an OTA roll out, it might take some time for the update to hit your device. Meanwhile, if you feel impatient, you can manually check for it by heading to your handset’s Settings menu.
