Otherwise, the adaptive frequency is called variable refresh rate (VRR). The difference with the screen refresh technology already installed even in affordable smartphones is that most of these devices refresh the image only at a few fixed frequencies (60, 90 or 120 Hz) and only by changing the display modes.
This is explained by the fact that the vast majority of smartphones do not support VRR, and support for devices with this technology is not implemented at the operating system level.
In this regard, Android 15 developers will add VRR support to the operating system, which will allow the system not only to adapt to the actual frame rate of the content without the need to switch, but also to change the refresh rate within the same display mode. . But this will only be available on some smartphone models, most likely flagship models.
It is also noted that although the previously implemented screen refresh technology determined what type of image was displayed on the screen, it was never truly adaptive. This is what introducing variable updates to the system is supposed to fix.
