Verizon has released an OTA update for the users of the DROID DNA on Verizon. It’s the first one since the updated last April for Android 4.4, and this one corresponds to the software version 4.09.605.5.
In the Verizon web site you can find the full list of enhances that this new version will bring to the DROID DNA:
• Integration of OpenSSL security patch updates
• Device root vulnerability issue has been resolved
• Improvement to Softcard activation and functionalities
• Improved compatibility for Miracast functionality
• Updated WiFi Connection Status Indicator on Notification Screen
• Updated Battery indicator when connected to PC via USB cable
It mainly includes some improvements and security fixes, and it also corrected some issues for the new 4.4 Android version. There is one point, however, that deserves special attention. The fact that the updated resolves device root vulnerability may imply that the device will be much harder to root.
So, before installing this update, think carefully about the chances that you might attempt to root your device. If you are not going to try, then the update is a welcome new. If you prefer to stick with a rooted DROID DNA, then you should better skip this update.
If you want to manually update the phone, you just have to follow these steps:
1. Go to Settings, under the option “All apps”.
2. Go to “Software update” and tab on “Check new”.
3. Choose download to get the file, and be sure to be using the Wi-Fi network, as the file is rather big.
4. When the download has been completed, the system will ask you to start the installation process. During the installation, the system will reboot several times and you won’t be able to use the phone for about 10 minutes.
5. Once ready, you should see the software version updated to 4.09.605.1.
