Substratum itself is a theming framework that leverages Android’s overlay mechanism to apply resource-level changes without modifying system partitions. When properly implemented, Substratum themes are modular—users can pick which overlays to enable—and reversible, restoring stock appearance when overlays are disabled. This architectural approach keeps changes contained and reduces the risk of bricking devices compared with more invasive modifications. However, compatibility depends on the Android version, OEM restrictions, and whether the device allows overlay injection. For recent Android releases and many vendor ROMs, additional steps (custom kernels, root, or specialized plugin support) may be required to achieve full theming functionality.
