Hello 4157Family,
We would like to see how we can help you with your photos not being as sharp as expected. If you turn Lens Correction off, does the issue persist? Follow the steps in this link to turn it off: Change advanced camera settings on iPhone - Apple Support
"Turn Lens Correction off and on
On supported models, the Lens Correction setting adjusts photos taken with the front camera or Ultra Wide camera for more natural-looking results. Lens Correction is on by default.
To turn off Lens Correction, go to Settings > Camera, then turn off Lens Correction."
Cheers
