Android has always offered more in the area of customization when compared to iOS. Rooted devices have the potential for a massive variety of tweaks and hacks, everything from overclocking, right through to theme and layout appearance. Not having root access, however, has its limitations, when it comes to personalization, especially in the theme department. That is of course, until recently. With the anticipated release of the Andromeda add-on for Substratum, rootless devices can have fully customized theme support.

Substratum, which is a theme engine that uses the Overlay Management Service or OMS, was only useful to rooted devices. Since the Andromeda add-on, however, not having access to root is no longer an issue for most devices running Android 8. The great thing about using Substratum along with the Andromeda add-on is that you don't have to worry about running command line prompts or any code.

The focus of this tutorial is getting both Substratum and the Andromeda add-on up and running on a device (Google Pixel) running Android Oreo. Although the Andromeda desktop client is available on Mac and Linux, we'll be using a Windows machine for this tutorial. We'll provide links to the Mac and Linux desktop clients, so if you're not a Windows user, don't fret.

**Please Note**

Substratum is a free application, but the Andromeda add-on cost $1.99 (USD). We'd also like to mention that Andromeda is an unreleased app and it may be unstable, but it has been reported to work with; Nexus 5X, Nexus 6P, Google Pixel and Pixel XL. If you're running Android Oreo, your device should work fine.'
