On the Google's Samsung Galaxy Nexus there is a 'widget' pre-installed that looks just like something from "Power Control". It has four icons from left to right that I think indicate: Wi-Fi Bluetooth ??? (white circle with square around it) turns auto-sync on/off Screen Brightness I've also installed "Power Control Plus", which is very similar, but is configurable, and which also has labels explaining what each function does. This lead me to a few questions..... I called the support number for Google, but the tech there wasn't sure of the answer. On the above list of the controls, what is the one listed up above with question marks? The "pro" version that I bought seems to do the same thing, but is configurable and has labels for what the controls are/do. The only thing I haven't yet gotten the pro version to do, is to select the "automatic" screen brightness. For screen brightness, I like the automatic control setting, but I wish I could simply select a way to move the whole thing up or down. In other words, if the screen is too dim indoors for me, I want to make it brighter - but when I go outdoors, I want the phone to automatically bump up the brightness even more. As things are now, if I increase the brightness setting indoors, when I go outside nothing happens at all, meaning I can't even see the data on the screen. Is there any way to get the "automatic brightness" control to work, but set the whole thing higher or lower, so the screen gets a little brighter in ALL possible conditions?
