Common Causes
Quick Fixes
1. Restart the Device
A restart resets the camera engine and clears temporary processes that cause freezing.
2. Close Background Apps
Swipe up → Close apps like Instagram, Snapchat, TikTok, and WhatsApp. These apps often keep camera hooks active in the background.
3. Lower Camera Settings
Settings → Camera → Formats → Most Compatible Settings → Camera → Record Video → 1080p 30fps
4. Turn Off Live Photos
Live Photos can freeze the camera when the sensor is under thermal load.
5. Remove the Case
The iPhone 15 warms quickly during camera use. Thick cases trap heat and trigger throttling.

Settings → General → Transfer or Reset iPhone → Reset All Settings Fixes corrupted camera preferences and animation bugs.
2. Free Up Storage
Settings → General → iPhone Storage Keep 10–15 GB free. The iPhone 15 stores temporary image data.

4. Disable Smart HDR
Settings → Camera → Smart HDR → Off Reduces processing load on the A16's ISP.
FAQ
Why does the camera freeze only when warm?
The iPhone 15 throttles the image processor to prevent overheating.
Is this a hardware issue?
Usually not — freezing is almost always software or thermal.
Does lowering resolution permanently affect photos?
No, it only reduces processing load. You can switch back at any time.
How long should I wait after removing the case?
Usually 5-10 minutes. Let the phone cool down naturally.
