Sensor size matters far more than megapixels for smartphone photo quality; a 4x smaller sensor means 4x more noise and lost detail.
Key Takeaways
Lens grime is the most common cause of blurry shots; wipe the glass before every photo.
Sensor size drives low-light performance: the Nothing 3a Pro (1/1.95”) outresolves the Samsung S24 telephoto (1/3.94”) in daylight, and the gap widens at night.
Noise reduction smooths grain but destroys fine detail like leaf veins and fur texture; more light is the real fix.
Megapixel counts are marketing: phones default to 12MP regardless of sensor rating, and extra pixels only help if the image isn’t already noise-blurred.
Exposure clipping on bright areas (especially skin tones) is worse than underexposure; tap-to-expose and use the brightness slider.
