I updated to 4.3 and have some issues and questions about it. Hopefully they're user options but I can't seem to find where and what to change. The issues are:
1. The screen comes on with the time, emails, etc. if my hand is near the screen. Can I turn this off?
2. The brightness is not adjustable by pulling down the settings. I have to go to Menu, Settings, Display and Brightness. Can I get this option back on the pull-down on my home screen?
3. The pattern lock is set for left or right handed but I used to have it cover the whole screen. Can I enlarge this?

I hope these are all just settings and I can change them. Thanks in advance.
