Its an additional EVF/LCD mode, you can change back to the way you are used to.
Interestingly as you get to know this new mode its actually quite cool.
Basically teh way it works is turn camera on, LCD will be on and show you the live view. Bring camera to eye, remove camera from eye LCD still in live-view. All is good and as before.
Put camera back to eye EVF switches on, take a shot, remove from eye, low and behold automatic picture review with option to click OK. However and this is where it get interesting, put camera back to ey and EVF turn on automatically and you can carry on taking pictures until you again remove the camera from you eye and it will automatically show you the last picture on the LCD again in preview mode. Its basically an auto-chimping mode. Basically with this mode you shoot with EVF until you think you have a keeper and when you remove camera from your eye it automatically presses the play button for you, if your keeper turns out not to be sharp, put camera back to eye and carry on shooting, rinse repeat. I like using this mode with preview turned off (0 Secs) as then I get uninterrupted shooting through EVF, but if I want to check I just pull camera away from my face.
Its great though because the whole time the camera is at your eye you can shoot seamlessly it will not stop you taking a shot, which is what annoyed me at first because I kept hitting okay before putting it back to my eye because that is what the screen told me to do, but its unnecessary, you only need to hit okay if you want to go back to live view on the LCD.
The app I used with me XT1 and Android ver 6.0 seems to work fine on the XT2. All functions were recognized by the XT2, focus, SS, Aperture, ISO, movie m0de. Haven't tried bracketing with the remote. I did notice its a little fussy on the initial handshake but seems to connect without issues. Can view images on both cards, copy to phone or cloud, so far so good.
