I have a question regarding my V712. Everytime my V712 for example is asleep then I want to use, of course the first thing I'll do is to press the power button for it to switch on and so I can unlock it but the problem is that it is not that responsive or quick. Every time I press the power button it takes like 3 seconds before it switches on. It is not like any other electronic device that when you press the power button it just switches on. Though every time I press the power button to switch it off (put it to asleep) it responses quickly. I have this problem since I bought it, is there any fix for this? I can live with it, but it is just kind a annoying.
