When I lower my phone’s brightness, I notice that the gray color on my phone doesn’t turn off, making it look like the display contrast changes. I wonder if it’s just a software issue. I updated from iOS 18.2 to 18.2.1 hoping that it would fix my screen issues, but it still doesn’t. Is there any solution to this?
It's not always the iOS update's fault! Many things can cause phone problems. If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.
Remember, the right question often leads to the solution!
iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.
Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.
Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

That’s normal for any screen. Screens are composed in almost all cases of Red, Green and Blue pixels (RGB). Depending on if the graphics card is 8 bit, 10 bit, 16 bit etc. will determine the maximum value of each pixel. The screen has to be capable of displaying higher bit depth too.
The easiest example is 8 bit color. Each color, R, G and B has 256 values, 0 to 255. The value of 0 is black and the value of 255 white. Values 1 through 254 are different luminous values. 1 being a very dark shade and 254 very light shade.
The 256 values for R, G and be combine to create 16.7 million colors (256 X 256 X 256 = 16,777,216). When equal values of R, G, and B are set, it’s a shade of gray. Middle Gray is a value of R128, G128, B128.
Lowering the brightness of a screen lowers luminous. Areas of the screen that should be white will be gray If the screen follows color accuracy settings and internal profiles.
iPhones have some adjustments that may help. You can adjust the internal white point in the Accessibility settings. Also, TrueTone slider can adjust color temperature.
Iphone 12 low brightness low contrast, screen becoming gray at low brightness
