If you own the T-Mobile model of the Samsung Galaxy S7 or Galaxy S7 edge, expect to see a new update notification soon, because T-Mobile is updating both devices.
The biggest part is the inclusion of the September security patches, which is very important. T-Mobile’s changelog has a a “time/date update” and various system improvements. The update screen on the device mentions new Samsung Cloud features as well.
Before the update, make sure you’re on WiFi (unless you’re rocking unlimited data) and have a good amount of charge. Head to Settings > About device and check for new updates!
