Thank you for your interest in OAI! Please try to add more information about the device, by filling out the 4 fields in your issue. Please also provide images for an OS and recovery (currently only TWRP) and so on - if possible. Also please confirm, that you are in possession of the device and are willing to test the config.

Seems to be the galaxy s20 ultra (exynos), which does have official twrp and unofficial lineage builds. x1s and y2s seem to be similar in support.

These are the asserts. https://github.com/TeamWin/android_device_samsung_z3s/blob/android-11/BoardConfig.mk#L76 https://github.com/TeamWin/android_device_samsung_x1s/blob/android-11/BoardConfig.mk#L76 https://github.com/TeamWin/android_device_samsung_y2s/blob/android-11/BoardConfig.mk#L76
