Verizon Wireless is issuing a software update for the Galaxy S7 and Galaxy S7 Edge, and it appears to be a security patch update along with the usual bug fixes, at least according to Verizon's changelog. They don't mention which security patch this is, but it is a recent one (likely April or May 2017). The Galaxy S7 and/or Galaxy S7 Edge will need to be connected to the internet for the software update to initiate. Once the update has started, the device must be turned on at all times during the downloading process. With this, it is recommended that the battery be fully charged in order to achieve the optimum performance of the software update.
Under the Software Version NRD90M.G930VVRS4BQC9 for Galaxy S7 and NRD90M.G935VVRS4BQC9 for Galaxy S7 Edge, the package includes the latest Android security patches on these devices that are most useful given the vulnerabilities in software and operating systems. As always, scheduled updates are useful to bring the best out of the device and remain an essential part of device maintenance, as Verizon Wireless commits to providing a reliable network connection to bring these updates. Upon completion of the software update, applications on your device may still take a bit to open, as the device will need to rebuild the cache that the apps create (which result in faster load times later on). In cases when the software update has prematurely stopped, the user can get help from Verizon Wireless’ Software Upgrade Assistant tool as it guides you with troubleshooting. Verizon Wireless also provides an Operating System FAQs link for those who want to discover the ins and outs of their devices through its OS. Customers can also look into what Verizon has in store for Samsung devices as well as promos and upgrades to entice its customers to acquire a new Samsung smartphone.
The update is rolling out now to both the Galaxy S7 and Galaxy S7 Edge on Verizon. You can head to Settings, then tap on About Phone and Check for Updates to bring down the update and begin the download. It does keep you on Android 7.0 Nougat, for those that were wondering.
