iPhone 16 dim despite full brightness setting

I tried turning my phone off and on again. I made sure auto dim is off. I slid the toggle to full brightness. None of that helped.

As Lawrence Finch states, if your iPhone is operating beyond its normal operating temperatures, it can dim its brightness to avoid overheating until it cools down. No matter what Settings or what you set the brightness to will not change this safety feature. Try moving it to a cooler environment, it that doesn’t do it, Lawrence Finch may be write in that you may have a hardware problem that needs to be looked at your nearest Apple Store’s Genius Bar or Apple Authorized Service Provider.
