What to do
- Free up storage space if it's under 10% available.
- Restart the phone to clear background memory use.
- Update the camera app or the OS if an update is available.
- Close unused background apps before using the camera regularly.
- Force-close and reopen the camera app to rule out a temporary glitch.

When to call a pro
If the built-in camera app is consistently slow on an otherwise fast phone, a repair shop can check for a hardware or firmware issue with the camera module.
