Ever since iOS 11 or 12 (whichever the mid-2017 iOS upgrade was), my 64GB iPhone SE camera’s functionality has been diminished:
The camera no longer focuses very well (e.g., taking a photograph of a 8.5"×11" page of 12pt text results in mostly unreadable blur, even in bright lighting conditions.)
The camera's resolution has been nerfed, with resolution maxing out at about 1150 pixels by 1530pixels, or around 15% of the nominal 12MP resolution. Back in 2017, the camera took pictures that were 3000 pixels by 4000 pixels
- I am using the rear-camera, not the front-facing camera
- Restarted the phone
- Cleaned the camera lens; and had my iPhone repair friend clean the camera inside the case
- Hard reset the phone
- Factory reset the phone
- Insured that HDR and Live Photo are disabled
- Tested with camera Flash set to Off, On, and Auto
- Tested by replacing the camera with a brand new camera at my local iPhone repair shop which produced identical results (opted to keep original camera in light of this).
- Under Settings > Photos I have Keep Originals checked
- Under Settings > Camera I have tried Keep Normal Photo checked, and unchecked, and neither setting affects the problem
- Under Settings > Camera I have tried Record Slo-Mo at both 1080p and 720p, and neither setting affects the problem
- Under Settings > Messages Low Quality Image Mode is off
- I only use the native Camera app, and have no other camera applications installed.
- The current battery health is fine, and is not triggering reduced performance.
I do not use, and have never used iCloud, so I suspect this is not an issue of having used too much iCloud storage.
How do get normal functionality back on my iPhone SE camera?
