AT&T updates Samsung Galaxy S7 and Galaxy S7 Edge
Google unleashed this month's security update two weeks ago, and now AT&T apparently launched it for the devices in the Galaxy S7 family on its network. However, it seems they added a few extra optimizations to the original code, but there is no official change log available yet.
According to Caden Brewer, a user of the Android Central Forums, AT&T is deploying already the new firmware via OTA and many others confirmed the size of the package is 173 MB. Next to the April security patch, it seems like various touchscreen and performance improvements have been added as well. Adranalyne, another user of the same forum, claims the display of its Galaxy S7 Edge "does feel a little differently in how it's reacting."
In addition to the above, more users confirmed a lower Android system usage than before. Enhancements for the palm rejection functionality have been noticed as well. As usual, those who did not receive the OTA update notification yet can go to Settings>About Device>Software Update and hit the Update Now button.
