iPhone 14 Pro Max screen turned green with siren sound

My iphone 14 pro max screen suddenly turned green (see below). I tried to power cycle it but it gave off a siren like sound. I then also tried the full restart (volume up, volume down, long power button hold), which didn't help. Grateful for any advise?

Thank you for your post.


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


Therefore, I recommend service.

Facing Green / Yellow Screen issues? Here's what worked for me:

  1. Backup on iCloud/iTunes - If enabled daily, wait for the time of day when iPhone backs up automatically.
  2. Try this --> Force restart iPhone - Apple Support


After the iPhone starts...

1️⃣ Backup on iCloud/iTunes

2️⃣ Log out of Apple ID

3️⃣ Erase (Keep eSIM Data)


❌ DO NOT restore from backups! Set up as a new iPhone. Wait 2-3 days - no issue! That Indicates...

✅ No hardware/ iOS issue


Now...

📦 Restore data gradually

🔍 Find app/settings causing the screen flickering
