Just wanted to share one of my favorite apps. I’m a control freak when it comes to brightness of my screen and how much precious battery my S4’s screen uses. The red bar at the top right is my adjuster that I slide left and right to adjust the brightness from 1 to 100%. The bar is not visible except when you use it and can be put anywhere you want. ( For screenshot I left it visible). The greatest thing about this app is that it works even if the phone is locked. Say you leave a dimly lit room and have your screen set very low and head outside to a very bright sunny day, your not going to see a thing on your phone and can’t even see the screen to enter your passlock. Screen Brightness is ready and just slide it over. If any of you customize junkies haven’t tried this app I highly recommend giving it a try. Like LL, I don’t think I’d love my phone so much without it.
