I HAVE TO KEEP IT TURNED OFF BECAUSE EVEN WHEN IT IS SUPPOSEDLY LOCKED. THE SCREEN WILL COME ON EVEN IN THE CASE AND IT KILLS THE BATTERY! Plus the slider is lose and it takes very blurry pictures, not that I expected much for use as a camera. But it is useless for me for people to call me at work. I only use it as a back up phone now at work. I bought a better one. Do not buy this junk!
