The majority of smartphones include the important feature of auto brightness. You no longer have to change the brightness on your phone by hand when the light changes. iPhones have also had this feature for a while, but it needs to be made clear when this simple feature will stop working.
There are several possible causes for this brightness issue, ranging from incorrectly configured settings to sloppy screen protector installation. But it would help if you didn’t manually adjust the brightness because of those factors. Using our compiled troubleshooting advice, you can solve your iPhone’s auto display brightness problem.
What Leads To The iPhone’s Auto-Brightness Problem?
The iPhone’s auto brightness may cease functioning for several reasons. For instance, the problem might be caused by a screen protector that is defective or damaged, by dust obstructing the ambient light sensor, or by an inexpensive iPhone accessibility display text size replacement from a third party. In addition to all these factors, an unrelated software fault might always be the culprit behind your iPhone’s malfunctioning ambient sensor and auto-brightness feature issues.
Steps to Fix If iPhone Auto Brightness Not Working
Following are the top techniques for fixing if iPhone auto brightness is not working:
Remove the Screen Shielder
Your iPhone detects your current lighting conditions using the integrated ambient light sensor and modifies the screen brightness as necessary. The sensor in your screen protector can be blocked, making it impossible for your iPhone to change the auto brightness. So, you should remove any screen protector to see if it helps.
In the same way, consider removing any protective cases covering the top sensors if you’re using them.
If iPhone Auto Brightness is Not Working, Clean Up Your iPhone
- The next thing you should do is wipe your iPhone with a gentle, dry towel after removing the cover and screen protector.
- The top of the notch houses the integrated ambient light sensor.
- Any sweat or grease that may have been covering the sensor can be removed by cleaning it.
It’s now time to update the iPhone auto-brightness not working settings. You may have previously tried this, but it’s still worthwhile.
- Step 1: Launch the iPhone’s Settings app and select Accessibility.
- Step 2: Click iPhone displays & Text Size under Vision. Turn off the switch next to the iPhone auto brightness at the bottom of the page by scrolling down.
Avoid Using Low Light Mode
If you’ve been using the iPhone Screen Zoom tool to make things easier to read, it’s possible that the auto-brightness setting is being messed with. In particular, if you unintentionally turn on low-light mode, your iPhone’s brightness will remain low. This is how to alter that.
- Step 1: Access your iPhone’s Settings menu. Zoom can be found under Accessibility.
- Step 2: Tap Zoom Filter, ensure Low Light is not selected and restart your iPhone.
Turn Night Shift Off
- The Night Shift feature occasionally conflicts with the auto-brightness option, much like Screen Zoom.
- Consider turning off this function by following the instructions below if you’ve been using it to lessen the blue light emanating from your iPhone.
- Launch the Settings app and select Display & Brightness in the first step.
- Open the Night Shift settings in step two.
- Next, deactivate the switch next to Scheduled and Manually Enable Until Tomorrow.
Now would be an excellent time for iOS updates, if needed. Search for and apply any pending iOS updates. A bug is likely acting up with the auto-brightness if you still need to update the iOS version of your iPhone.
Open the Settings app also on your iPhone to check for software updates. Go to General and click the menu option for Software Update.
Any pending updates should be downloaded and installed. You should also examine if your iPhone can adjust the brightness independently.
Quit IOS Beta
Problems arise from utilizing any version, not simply an outdated one. Such problems can also occur when using iOS beta releases for early adopters. Many iPhone owners using the iOS 15.2 betas reported issues with the auto-brightness feature. Thankfully, once they moved to a stable build, the problem was fixed.
You should update to a stable build to resolve the iPhone’s auto brightness feature issue.
Automize and Unwind
When it comes to screen brightness, there is no one ideal setting. Your screen brightness should automatically adjust as you switch between different lighting situations for a comfortable viewing experience.
The options above should make it simple for you to resolve any problems with the auto-brightness feature that may be causing you to adjust brightness manually constantly.
That’s it! Has the auto brightness function on your iOS device reverted to normal? I sincerely hope one of these excellent fixes resolves your iPhone’s annoying problem.
