The Samsung Galaxy S8 and S8 Plus may have only been released last week but they are already receiving updates from carriers here in the United States that carry them. AT&T, T-Mobile and Verizon all have released updates to the new flagship devices which should be hitting those who own the phone via an OTA update over the course of the next few days. The update is about 300MB in size across all of the carriers.
All of the updates contain the April 2017 Android Security update as well as baseband updates for each of the carriers. These two reasons alone make this a must have download as it assures the security of the device as well assuring it will work optimally with your carrier of choice. This update also addresses general performance improvements around the display and fixes some known bugs with the software.
