There's 13-megapixel effective resolution from the standard sized 1/2.33-inch CMOS sensor. On the back is a very impressive 5-inch, 1920 x 1080 pixel Full HD touchscreen AMOLED display, and the S4 zoom runs the Android 4.2.

1920x1080 resolution The display on the Galaxy S4 is a major enhancement and improvement over the Galaxy S III – it has a full HD 1920x1080 resolution display with 441 Pixels Per Inch.

3840 x 2160 pixel As things stand, the majority of 4K displays come with 3840 x 2160 pixel (4K UHDTV) resolution, which is exactly four times the pixel count of full HD displays (1920 x 1080 pixels). There are also 4096 x 2160 pixel (DCI 4K) displays for the film industry that are referred to as 4K displays.

That means the TV has 3,840 horizontal pixels and 2,160 vertical pixels, for a total of about 8.3 million pixels. On TV product specifications, resolutions are usually shown as "3840 x 2160" for 4K TVs.

The S4 was made available in late April 2013 on 327 carriers in 155 countries. It became Samsung's fastest selling smartphone and eventually Samsung's best-selling smartphone with 20 million sold worldwide in the first two months, and 40 million in the first six months.

While typically referring to motion pictures, some digital camera vendors have used the term "4K photo" for still photographs, making it appear like an especially high resolution even though 3840×2160 pixels equal approximately 8.3 megapixels, which is not considered to be especially high for still photographs.

1.90∶1 4K, also known as “DCI 4K,” is a format commonly used in high-end movie production. Its resolution is 4096 x 2160 and its aspect ratio is 1.90∶1, which is slightly wider than UHD or 16x9.

4K encompasses a broader range of resolutions, varying from approximately 3840 pixels to 4096 pixels in width. On the other hand, 2160p specifically denotes a fixed resolution of 3840x2160 pixels. 4K resolution provides greater detail and sharper images due to its larger number of horizontal pixels.

It's a fair assessment of the Galaxy S4 to say that the hardware, in particular, has stood the test of time extremely well. Not only do some components still easily outstrip any mid-range smartphone, they also give many high end phones a run for their money.
