For example, the Samsung Galaxy S21 Ultra has a screen with a diagonal measurement of 6.8 inches and a resolution of 1440 x 3200 pixels. Using the traditional method, the PPI value would be approximately 522. However, using the rectangle method, Samsung claims a PPI value of 534.

Moreover, invalid PPI claims can also lead to confusion and mistrust among consumers. If a manufacturer is seen to be exaggerating or misrepresenting their display’s capabilities, it can damage their reputation and erode trust in the brand. For example, the Samsung Galaxy S21 Ultra has
Pixels Per Inch (PPI) is a measure of a display’s pixel density, calculated by dividing the number of pixels in a diagonal line across the screen by the diagonal measurement of the screen in inches. In theory, a higher PPI value indicates a sharper and more detailed display. The human eye can only resolve a certain number of pixels per degree, so a higher PPI value can make text and images appear smoother and more refined. The Truth About Invalid PPI Claims on Samsung
However, not all PPI claims are valid. Some manufacturers have been accused of using dubious methods to inflate their PPI values. In the case of Samsung, some critics argue that the company’s PPI calculations are misleading or inaccurate.
The traditional method of calculating PPI is based on the diagonal measurement of the screen. However, Samsung has been using a different approach, known as the “rectangle method,” which measures the PPI of the screen’s active area, excluding the bezels and non-display areas. This method yields a higher PPI value, which some argue is misleading.
In conclusion, the controversy surrounding invalid PPI claims on Samsung devices highlights the importance of transparency and accuracy in marketing. While PPI is an essential factor in display quality, it’s not the only consideration. By understanding the facts and separating fiction from reality, consumers can make informed decisions when choosing their next smartphone.
