RK3566 Displays
The RK3566 series first went on sale in December 2021. A major hardware change took place in October 2022. Unfortunately, all tablets sold before this period cannot be updated to Android 13 because the motherboard was replaced. Consequently, the firmware available after October 2022 is also incompatible. The newer firmware has “v6” in its designation. All tablets sold after this period can be upgraded to Android 13. A further Android version upgrade will likely not be possible, as Rockchip, the CPU manufacturer, would need to provide it.
