Direct updates by OS vendor
It can be updated directly by the OS vendor, so no need to wait until the manufacturer or network provider releases an update.
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.
Reasonably more megapixel (photo, front camera)
2 MP vs 1.9 MP—5.26% more megapixel (photo, front camera)
Distinctly wider aperture
2.2 vs 2.6 —18.18% 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.
Sizably lower SAR for body (USA)
1.07 W/kg vs 1.49 W/kg—0.42 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.
Appreciably smaller semiconductor size
28 nm vs 32 nm—4 nm smaller semiconductor size. A smaller size indicates that the process to create the chip is newer.
