I turned up my brightness all the way and it still is much more dim that my friends same phone. I tried restarting it and it wouldn't open up for a long time and the screen would just freak out and twitch whenever I touch the screen. Once it finally opens up its still very low brightness. And it has nothing to do with auto brightness. I turned it off. Please help me. This is more frustrating than it seems. Thank you.
