Hi ifull0723 Thanks for your asking. ZC554KL provides Android P AOSP Software Image Beta Version, only allow manual update. Please note that this version is "pure" Android system, and will not have ZenUI. If you are used to and prefer using ZenUI, we recommend that you continue with the Android 8 (Oreo) version.
