iPhone 14 Pro OLED display shows temporary greenish and reddish color shifts

Temporary greenish and reddish color shifts on iPhone 14 Pro OLED display.


Hello everyone, I'm seeing temporary greenish and reddish tints on my iPhone 14 Pro display and wanted to know if anyone else has experienced the same.


What I notice:


1. Around 50% brightness, grey and dark grey areas briefly shift to greenish or reddish when brightness increases or decreases, either manually through the brightness slider or automatically through Auto-Brightness. The color shift only happens while the brightness is changing. Once the brightness stops changing, the colors return to normal.


2. Between 0% and 10% brightness, the same color shift occurs when manually moving the brightness slider or when Auto-Brightness automatically increases or decreases the brightness through this range.


3. Auto-brightness also triggers the shift when it moves through these levels.


4. It only happens in dark mode, not in light mode.


5. It mainly affects grey and dark grey, while white text stays normal.


6. The shift is temporary. Once the brightness is stable, the display looks normal again.


7. After watching HDR videos on Instagram or Facebook, when I return to a normal dark screen with a grey background, sometimes after 5 to 10 seconds, there's a quick green or red flash for about 1 to 1.5 seconds. The effect shows across the entire display. Is this expected with OLED screens, or could it be related to HDR transitions or something else?


Has anyone seen this on an iPhone 14 Pro or another OLED iPhone? Thanks for any insights.

Hi there


Please try this


  • Turn Off Auto-Brightness: If the shifting while walking through different lighting environments bothers you, you can lock the brightness manually. Go to Settings > Accessibility > Display & Text Sizeand turn off Auto-Brightness. 
  • Toggle True Tone and Night Shift: These features automatically alter your screen's warm/cool balance dynamically. Sometimes they fight with the gamma response during transitions. Test if turning them off reduces the effect by navigating to Settings > Display & Brightness. 
  • Keep iOS Updated: Apple frequently tweaks display calibration tables and display engine pipelines via firmware updates to smooth out transition artifacts. Ensure you are on the latest software version by navigating to Settings > General > Software Update.

My question is: Could this be considered normal OLED panel behaviour, particularly during brightness transitions, or could it indicate an issue with the display panel itself?


It is more likely that you have an issue with the screen / panel. Here I am assuming that you have been using the iPhone 14 Pro for a few years and you have not seen this issue appear until recently.


Follow the recommendations to have the iPhone tested at an authorized Apple Service Provider.


Your next question might be whether a screen replacement would be covered as a warranty repair.


Yes, if you have AppleCare+ coverage currently in effect. Typically, there is a small deductible ($29 U.S.) for covered repairs.


No, if you do not have AppleCare+ coverage in effect on your iPhone. In that case, you will pay for the screen replacement.

Welcome and thank you for reaching out. 🤗


There appears to be a problem with the internal display panel. Only a certified Apple technician can determine the cause and offer a complete solution.


Therefore, I recommend service.

Hi there,


Thanks for the suggestions. I've already tried all three steps: Auto-Brightness is turned off, True Tone and Night Shift are disabled, and I've checked the available iOS updates.


However, the issue is still present.

I've also attached a video link below where the behaviour is clearly visible, showing the temporary colour shifts on the display.

Hi Brian,

Thank you for your response and recommendations.


I understand your suggestion to have the display inspected by an Apple-certified technician. Before proceeding with a service appointment, I just wanted to clarify whether the colour shifts I'm experiencing could be a characteristic of OLED technology or whether they are more likely to indicate a hardware issue with the display panel.


I'd appreciate any further insight you can share.
