    Seriously, my phone's brightness refuses to change even though I've been sliding the bar up and down like crazy with absolutely no change. I've already tried restarting my phone to no avail. I believe it's probably a pretty internal problem which could mean I would need to do a factory reset. But I would rather only do that if it's absolutely necessary. Plus I know basically nothing about the problem and I don't know enough about the android system to gather information.

    Try first a Power Off and Restart.

    Welcome to Android Central! Which phone? See if this happens in Safe Mode. To learn how to boot into Safe Mode, you can either tell us the phone model, or you can do a search for "[phone model] Safe Mode."
