Apple has launched its flagship phone the iPhone X with many latest and unique features. Which makes it a revolutionary product so far launched by Apple. The FaceID and OLED screen are among these new features. However such high powered product from Apple is not fully protected from issues and bug.
Once such issue is reported by many users is linked to Phone Screen brightness. The iPhone X screen is randomly going dim automatically. Even when the phone is expected to get brighter rather it gets dimer eg in bright sunlight the iphone X screen display light gets dim. The users have tried with turning off auto brightness( general - accessibility - display accommodations - turn off auto brightness) but still the issue is faced by users. The dim screen of iPhone X is not permanent but iPhone recover from it after 15 minutes of usage.
But even if the screen comes back to normal light still the issue is very annoying as screen brightness sometimes get really very low and it’s difficult to use in bright sunlight. Many users report it as a bug as iphone x screen brightness changes randomly. As the issue happens with all iOS/iO11/iOS11.1/iOS/11/2 versions released, so it difficult to report it as an issue.
The low brightness of screen in iPhone X is not a bug but a phone feature as published by Apple that when phones gets hot the screen may get dim as it helps in getting cool soon. So if you are facing this issue so better to leave your device standalone for some time in some cool place and also a reboot may help to fix it.
From Apple support:
If your device gets too warm
If the interior temperature of the device exceeds the normal operating range, the device will protect its internal components by attempting to regulate its temperature. If this happens, you might notice these changes:
· Charging, including wireless charging, slows or stops.
· The display dims or goes black.
· Cellular radios enter a low-power state. The signal might weaken during this time.
· The camera flash is temporarily disabled.
· Performance slows with graphics-intensive or augmented-reality apps or features.
In case you are sure that your phone is not heating up and the low dim screen of iPhone X is not caused by overheating. Then like many other iPhone 6/7/8 users your phone might be affected by problem reported in iOS11. In that case consider contacting Apple customer care centre, Like one users reported that
“I had the same issue. Auto brightness is OFF and the brightness slider is UP on maximum but screen still keeps going down in brightness level by 1-2 shades. Contacted Apple support, they did some diagnostics and couldn’t fix it so replaced with a new phone”
