GoKawiilGuide outlines fixes for blurry iPhone photos
A photography guide explains several ways iPhone users can reduce blurry photos, including raising video/photo resolution in Settings > Camera, using tap-and-hold AE/AF Lock to fix focus, and enabling Night Mode on iPhone 11 and later for low-light shots. It also recommends third-party apps like Camera+ for manual shutter speed and ISO control, plus using a tripod to minimize camera shake.
