The Xbox button on my controller takes me back to the Android home screen.

I've had this happen myself. Do you have any luck if you press the white Home button on the controller? Does it bring up the menu on the left of the screen? For me, when I pressed Home in this menu, then it refreshed the Xbox and the screen would load
back to my Home screen on the TV.

Doesn't work for me either, pressing the 'start' button on controller 2 takes me back to the main screen?

try this, go back to home screen quit the app via options button on controller, then relaunch it will then work (did for me anyway)

Hello Happy,

thanks for coming to the forums with your question. You can hit the Xbox button also called guide button on the controller. Will bring up a menu on left side, home will be highlighted. You can hit the A button on home to take you to the home screen, or you
can go down to the game you playing hit the start button one with 3 lines, go down to quit. This will take you to the home screen also.

Thanks,

Brad

I'm having the same issue. I clicked on Spartan Assault and can't go back. I go to the Home screen, press my menu button and choose Quit. There are NO background instances of the Store running. I can even shut the console down and turn it back on but every
time I relaunch the store, it loads up by default to this same stupid game's page.

Seriously, Microsoft? How hard can it be to add a freakin' BACK BUTTON?????

EDIT: So I went back and cycled the power on my machine and even that won't work. The store still loads this game's page. Saying GO BACK or hitting B on the controller takes me to the XBox's Home screen, not to the store's main page. This is BEYOND ridiculous.
The store is completely broken at this point for me... even for the necessary apps I would like to download.
