How Does The Back Of A Samsung Tocco Lite Come Off?

There's a tiny arrow on the back of the handset, push in that direction. You'll need to push quite hard. It may help to use a tissue or something to get some friction.

Slide it down

As above: Follow the direction of the lil arrow: Hold it with both hands one thumb on the arrow (press it a lil) and the other thumb on the opposite, let it slide, viola!

As they have said before just slip down the way that the lil arrow is pointing

I'm finding it really hard to get off too. Nd I so want to turn it on!
