About the OPPO Reno4 5G
OPPO CPH2091BLK is listed in the smartphones category. The recorded specifications include display diagonal: 16.3 cm (6.4"); internal storage capacity: 128 GB; mobile network generation: 5G; operating system installed: Android 10. This entry covers manufacturer code CPH2091BLK. Specifications relate to this exact source record; other editions or packages may differ.
The 16.3 cm (6.4") display is specified at 2400 x 1080 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.
