T999UVALH2 U.S T-Mobile Samsung Galaxy S III SGH-T999 ICS 4.0.4 Firmware Update that Includes Brightness Slider

T-Mobile U.S recently released its first official Android 4.0.4 Ice Cream Sandwich (not Jelly bean 4.1.1) for Samsung Galaxy S III SGH-T999. The firmware build number is T999UVALH2, an update from previous build T999UVALEM.  This is an incremental software update that brings an additional feature such as the status bar brightness slider.

So far, this update is only available for T-Mobile users only in the U.S, Canadian users with the Samsung Galaxy S III SGH-T999V under Mobilicity, Wind and Videotron may still keep to wait for a while. In the U.S, the first Galaxy S3 got with an early update is AT&T's SGH-I747 .

In addition, Verizon and Sprint seems left behind and also likely all Galaxy S III variants in Canada  no signs of any update yet for now also.
