General A few questions from new Note 2 user

view story

http://androidforums.com – Hello, just bought the Galaxy Note 2 (Gray). I have a few questions: 1. When I went to the Music app, I noticed that there is only one song under Samsung album. The song is "Over the horizon". When I bought the Galaxy Note, there were 5-6 songs pre-installed. Why there is only 1 song? 2. What is screen time out? Which value is recommended? 3. Can I use all the staff from Galaxy Note on the Note 2? For example, usb cable, charger which came with Galaxy Note, S pen, etc. 4. What are the recommended settings for power saving mode? Thanks (General)
