Every pixel has three subpixels
The device has three full subpixels per pixel which results in a sharp and crisp picture. Pixels in some displays (like AMOLED) share one subpixel to preserve space. It may result in less crisp or little blurred image.
Has built-in optical image stabilization
Optical image stabilization uses gyroscopic sensors to detect vibrations of the camera. The lens and / or sensor move in response, adjusting the optical path. This ensures that any motion is corrected before the sensor captures the image.
Noticeably wider aperture
2 vs 2.2 —10% wider aperture. Aperture sizes are expressed in f-stops. The smaller the number, the wider the aperture. This means the sensor captures more light, helping to avoid blur by enabling you to use a faster shutter speed. In addition, a wide aperture provides a narrow depth of field enabling you to focus on the subject and blur the background.
Considerably lower SAR for body (USA)
0.69 W/kg vs 1.55 W/kg—0.86 W/kg lower SAR for body (USA). SAR (Specific Absorption Rate) describes how much radio frequency energy emitted by the device will be absorbed by your body. The rate is measured at hip level. The legal limit is 1.6 W/kg in the USA.
