The product, explained
About the Samsung Galaxy S21 Ultra 5G SM-G998B
Samsung SM-G998BZSDEUA is listed in the smartphones category. The recorded specifications include display diagonal: 17.3 cm (6.8"); internal storage capacity: 128 GB; mobile network generation: 5G; operating system installed: Android 11. This entry covers manufacturer code SM-G998BZSDEUA. Specifications relate to this exact source record; other editions or packages may differ.
The 17.3 cm (6.8") display is specified at 3200 x 1440 pixels. Consider these together: a larger screen provides more physical space, while resolution determines the number of pixels available. Neither specification establishes brightness, colour accuracy or motion quality.
The listed maximum refresh rate is 120 Hz. A higher refresh rate can make scrolling and supported games look smoother. The rate used depends on the app and display settings, and can affect battery life.
