Hello Brandonladonn,
Thanks for reaching out to the Apple Support Communities! We understand you are seeing some issues with the display on your iPhone flashing to a blue color. We are happy to provide some guidance.
To start, could you let us know if you are using Night Shift or True Tone on your iPhone? You can find Night Shift and True Tone by going in to Settings > Display & Brightness:
Adjust the brightness on your iPhone, iPad, or iPod touch
Use Night Shift on your iPhone, iPad, and iPod touch
If you have those options turned on, try turning them off and monitor for that behavior again. If the issue continues, we'd like to ask a few more questions to get a better understanding of the situation.
- When did you first notice this behavior? Was it after any sort of change or update to the device?
- What iOS version is on your iPhone? You can check in Settings > General > About
- Is there any water damage or physical damage to the device?
Keep us updated on the situation, we are happy to help!
Best Regards.
