History Details
You can click on that graph I mentioned in order to expand it out to the history details

Wallpaper
- There are a lot of really cool animated wallpapers that you
can use with android called Live Wallpapers. However, these consume more

Sleep
- Right under this option, you will see the timer that your phone has

phone every time. You set a phone lock with a pin, password, or another se-
