Thanks for the advice Pow and Stevie.
Well, it back to works again until now. But, I didn't do anything on it! I don't understand why it froze for 5 days and now back to works. Can somebody explain this? So far the trackpad condition is good. When it freeze, it just need a couple of battery pull. And I thought it was a normal for my device. Now, it is a huge relief for me.
But, there was a couple of error on my device since on its unboxing. Which is the camera are way to blur...for distance 10cm further i can't see anything caused by the blurry camera. Second, phone call audio is too small to hear. I almost didn't hear anything including the waiting tone. I adjusted all the settings for the camera and phone call audio but nothing has changed.
