What is True Tone?
Before knowing how to check it, let's first understand its function.
True Tone Functions in Brief:
True Tone is Apple's proprietary display technology that:
- Adjusts the screen white balance according to ambient lighting.
- Makes the screen display look more natural and comfortable on the eyes.
- Reduces eye strain in long-term use.
- Usually available on iPhone 8 and above, iPad Pro, and some MacBooks.
True Tone Features Not Working
Before performing a technical check, pay attention to the following signs that may indicate True Tone is not active or not working:
- Screen colors appear too bluish or yellowish in all lighting conditions.
- There is no change in screen color when moving from a bright to a dark room, or vice versa.
- The “True Tone” option does not appear in the display settings.
- The device has had a screen replacement (non-original).
How to Know if True Tone is Working or Not
Here are the exact steps to find out if the True Tone feature on your iPhone is active and actually working:
1. Check in Screen Settings
Log in to:
Settings > Display & Brightness
See if the True Tone option is available and active.
- If the option appears and can be enabled/disabled → the device supports it and can be tested.
- If it doesn't appear at all → most likely the screen has been replaced or the device doesn't support this feature.
2. Perform Manual Testing
Once True Tone is enabled, try testing it under different lighting conditions.
Steps:
- Enable True Tone.
- Go to a bright room, pay attention to the screen display (it should look balanced and not too blue).
- Enter a dark or dim room, and check again to see if the screen colors turn slightly warmer.
- Compare with True Tone mode turned off: the display should look different.
3. Use Another Apple Device (Optional)
If you have another iPhone of the same type and have never had the screen replaced:
- Place both iPhones side by side.
- Enable True Tone on both.
- Change the ambient lighting and see the difference.
- If one changes and the other doesn't, it's possible that True Tone on one of them isn't working.
4. Use Diagnostic Application
You can also use a third-party app or take your device to an Apple Authorized Service Provider for diagnosis.
Some applications such as:
- 3uTools (for Windows users)
- CoconutBattery (for Mac users)
It can display the status of the screen sensors and True Tone features, although this is more technical and not everyone will be comfortable using it.
Causes of True Tone Not Appearing or Not Active
Some factors that can cause the True Tone feature to be unavailable or not working:
Screen Replacement
- Non-OEM (Original Equipment Manufacturer) displays typically do not have sensors that support True Tone.
- If you have ever replaced your screen at an unauthorized location, there is a good chance that True Tone will be permanently lost.
Bug or Glitch
- iOS updates sometimes cause features to not appear. Make sure you are using the latest version of iOS.
Sensor Damaged
- A damaged or covered ambient light sensor can also prevent this feature from working.
Additional Tips
To keep True Tone optimal:
- Use a screen protector that is clear and not too thick .
- Clean the screen regularly , as dirt can interfere with the sensor.
- Do not cover the top of the screen when using in various lighting conditions.
So the conclusion is
True Tone is an important feature for visual comfort that iPhone users often don't realize. To find out if True Tone is working or not, you can simply look at the options in the settings and do a simple test in various lighting conditions. If it doesn't appear, it's likely that your device has had a screen replacement or is experiencing sensor problems. Make sure you use an original screen if you want this feature to remain.
If you feel this feature is missing even though it was previously there, it is highly recommended to check the device's repair history or take it to an Apple authorized service. This feature may seem small, but its impact on eye comfort when staring at the screen for a long time is very significant.
