Back button does not light-up when I press home button I bought a Samsung Galaxy Y phone yesterday. I was wondering why the Back button does not light up when I press Home button on the device. 

On my Samsung Galaxy Ace the Back button and Menu button light up immediately whenever I press home button.

Is there a setting associated with this that I need to change?
The Galaxy Y GT-S5360 simply does not have backlighting for its capacitive buttons (source 1, source 2) whereas the Ace does - there is nothing you can do.
