Welcome to Android Central! Is this for both static and live wallpapers?
Also, the question you ask in your post seems to be different from the question in your thread title. Keep in mind that the Galaxy A03 Core is a budget Android Go phone, so it is quite underpowered, and Android Go is a pared-down version of Android for these kinds of cheaper phones. As such, it won't support as many apps, and performance will generally be subpar.
