AT&T has started to roll out May security update for the Samsung Galaxy S6 Active smartphone. The update is currently rolled out via OTA. Hence, it will take few days for the update to reach your handsets. If you have access to Samsung Galaxy S6 Active, you will receive a message notification. You have to proceed as per the instructions outlined on the update page.
With software version G890AUCU6DQE1, the update for the Samsung Galaxy S6 active (G890A) features a build number NRD90M.G890AUCS6DQE1 alongside kernel version 3.10.61-10950877. However, you should install G890AUCU6DQD1, which is the build number of the previous update.
When you receive another update after two months, you should have installed the latest update which is G890AUCU6DQE1. Hence, it is absolutely essential for you to keep your handset update with latest updates to avoid double work at a later stage. You can easily install the update via 4G mobile connectivity because the size of the update is only 15.6MB.
It is not essential for you to charge the smartphone beyond a certain level before the installation of the update. Even if you have 45 percent charge, you will be able to install the update easily since the capacity is less.
If you install the update, your handset will be protected against viruses, malware and other security vulnerabilities such as ransomware. In addition to regular bug fixes, the latest update also improves the performance of the system.
If you are unable to view a message notification about the update, you can manually check for the presence of the update by tapping Settings menu. You should select Software update option to check for the update. The update will not cause any major damage to your smartphone but it is advisable to capture a backup of your data.
