How to fix the iPad home screen being dark purple? My iPad Mini's home screen is really dark and I think it's because of something I have done.

I have removed emoji keyboard as I thought that was causing it but the darkness still remains.

It sounds like you have your brightness turned down.

To change your screen brightness, tap Settings > Display &amp; Brightness and drag the slider to the right or left.
