Why are my phone’s photos and videos blurry?

Check the Camera Settings:
Make sure that the resolution and video quality settings of the camera are properly set.
Check Camera for Dirt and Debris:
Clean the lens and sensors of the phone camera with a non-alcohol wet cleaning cloth if there is dust or dirt.
Check Whether the Camera App is Up-to-Date:
Make sure the camera application is updated to the latest version.
Check Storage Space:
The phone should have sufficient storage capacity to store the images and videos properly. Good quality photos and videos require more space.
