Troubleshooting Procedures
If you notice screen discoloration or unevenness on your iPhone 14 display, try the following troubleshooting methods:
Step 1: Hard Reset the iPhone (Force Restart)
A hard reset involves completely shutting down the device and then restarting it. This can often help resolve any color-related issues caused by software glitches and recalibrate the display.
To hard reset/force restart your iPhone 14, follow these steps:
- Press and quickly release the volume up button.
- Press and quickly release the volume down button.
- Press and hold the side button until the Apple logo appears.
This will force your iPhone 14 to restart and hopefully fix any problems it is having.
Step 2: Adjust Color Profiles
When your device’s True Tone display is not calibrated correctly, switching between the standard and non-True Tone color profiles in the Settings can often help fix the issue.
The iPhone 14 uses a default color profile called DCI-P3. This color profile is used by most professional cameras and displays. It is designed to accurately represent the colors that you see in the real world.
If you are not happy with the way the colors look on your iPhone 14, you can try adjusting the True Tone setting.
True Tone is a feature that automatically adjusts the color temperature of your display to match the ambient light in your environment.
- To adjust True Tone, go to Settings > Display & Brightness > True Tone.
You can also try adjusting the Night Shift setting. Night Shift is a feature that reduces the amount of blue light emitted by your display. Blue light can interfere with sleep, so Night Shift can help you get a better night’s sleep.
- To adjust Night Shift, go to Settings > Display & Brightness > Night Shift.
By doing this, you can reset your device’s display settings and hopefully resolve any calibration problems you may be experiencing.
Step 3: Check for Overheating Issues
If your phone feels hot, it could be an indication of a problem with the battery or other internal components.
Allowing it to cool down completely to room temperature is a good first step in troubleshooting the issue. Once it has cooled down, check if any discoloration remains on the phone.
If there is discoloration, it could be a sign of overheating or damage to the device. In this case, it’s best to take your phone to a professional for further inspection and repair if necessary.
Step 4: Inspect for Physical Damage
When inspecting the display screen, it’s important to check for any physical damage that could impact the quality of the image displayed.
Cracks, warping, bubbles, or pressure points could all potentially affect the color output and clarity of the screen.
It’s best to thoroughly examine the screen before use to ensure that it’s in good condition and will perform as expected.
Step 5: Restore and Update iPhone
For persistent issues, try fully restoring your iPhone using iTunes and updating to the latest iOS version as a fresh software start.
