A new update has started rolling out to Samsung Galaxy S8 and S8+ units on T-Mobile's network. The update brings the option to hide the navigation bar - there's a new icon on the left of the bar that lets you do this.
The other change is related to the bar's background color - the range of available options has been enhanced.
Finally, the update also includes Android security fixes for the month of June - the security patch level now says June 1.
While those were all listed changes, early adopters found there's more to it. The update also blocks the option to remap the Bixby button, something which Samsung has done for the second time (the patch didn't prove effective the first time). However, currently only T-Mobile variants are said to be affected by this change.
It is also available in Poland on PLUS carrier. Just got an update. I have Galaxy S8+.
you can already used bixby voice on the galaxy s8+ on T-Mobile. Ive received the update for bibxy few week ago. they finally have it on English .
It's ridiculous for Samsung to block this is the US market until they actually get Bixby working here. Quite lame.
