iPhone Xr Screen Keeps Dimming
I have an iPhone Xr running iOS 15.1, and the screen keeps dimming on me. I constantly have to open the control panel and return the device to my desired screen brightness. Under the Display & Brightness controls the Appearance is set to Light, Automatic, True Tone and Night Shift are all off. Why does my phone keep doing this?
Thanks in advance!
iPhone XR, iOS 12
