Android 11, One UI 3.0 update is more widely disseminated in the states to Galaxy S20 series
According to Android Police word keeps coming in from U.S. owners of the unlocked Samsung Galaxy S20 series phones about the Android 11 update that they just received. The update includes One UI 3.0 making it the latest version of Samsung's user interface designed to make elements on a large-screened phone reachable to all. With One UI, users no longer have to perform calisthenics with their finger to reach a button on the top corner of a device. This is because Sammy moved the buttons toward the bottom of the display.
Reports about the update becoming available for unlocked units in the states first were seen on December 21st. At that time, some Samsung owners were staring at the calendar doing double takes with some noting that this was the earliest that they have ever received an Android update on their Samsung handset in the U.S. (beating out last year's Android 10 update by a couple of days). The update (with Android 11 and the One UI 3.0 interface) hit the unlocked U.S. Galaxy S20 series not too long after it started to surface on carrier-locked models from Verizon, T-Mobile, and AT&T.
