In the tips and tricks thread, NeoGrandizer posted the follwing tip: ...which sounds to me if I turn auto brightness on, then the slider bar changes from a free-floating percentage bar to one with fixed points. However, when I try this, the brightness bar acts in one of two ways, depending on where I'm trying to adjust it from. If I'm trying to adjust it from the settings menu, then after I check the box for auto brightness, the bar just greys out and won't allow me to change it at all. From the notification pull down, the bar also greys out when the auto brightness box is checked, but I can still move the slider around; the check in the box instantly disappears if I do, though. Since Neo mentions that the setting is on a Note 2, I would argue that the different phone is the reason for the discrepancy. However, other users who are using Note 3s say they see the same functionality. So here's where I need your help, fellow forum users: as the thread title states, how does your auto brightness function? Does it perform as Neo suggests, and there are specified levels you can adjust it to after it's turned on? Or is it more like mine, and you're only given an either/or option? Or does it do something entirely different? Whatever the case may be, please provide screenshots and phone info, if possible. Ultimately, I would like to learn what's different about my phone over others that could explain the difference in features. So here's my screenshots: ...and my info: Carrier: Sprint Software version: N900PVPUBMJ4 Android version: 4.3 Kernel version: 3.4.0-1646606 Let the discussion begin!
