I have the "Display & Brightness" feature of iOS disabled, and yet the device still dims to a brightness level that is unreadable after about 10secs of inactivity.. How do I turn this off?
I was having the same trouble with this. My auto-lock was already turned off, but my phone continued to keep dimming and I couldn't figure out why.
I eventually realized my power-saving mode was on which makes it dim automatically. Make sure yours is off: Settings > Battery > Low Power Mode > Off
