How to Install Substratum on Galaxy S9/S9+[No Root]

Substratum is the most popular theming solution available for Android at the moment. Now, you can install Substratum on Galaxy S9 and Galaxy S9 Plus without root. Even though Galaxy S9 has native theme support, Substratum themes for Galaxy 9 look really well. Read ahead to download and install substratum for Galaxy S9 and S9+.

A couple of years ago, Substratum did not even exist. Those were the days of CyanogenMod. In those days, you cannot customize all the Android devices with themes. If you wanted to install themes on your device, the only solution was to install a custom ROM on your device. CyanogenMod came with a built-in Theme Engine, which was really good. With that, you would be able to theme every nook and corner of your Android.

With the unfortunate demise of CyanogenMod, we all badly needed a replacement. Substartum is the answer to all the Android Theming needs. In this tutorial, we will tell you how you can install Substratum Themes on  Galaxy S9 and Galaxy S9+.

Initially, when Substratum was introduced, they only had support for rooted Stock Android devices. With the introduction of Android Oreo, they introduced a way to rootlessly install Substartum on Android Oreo devices. That was a major turning point in the Android Theming history. You no longer needed root to freely theme your device!

Then a few months after that, Substratum announced the support for Samsung Galaxy devices via a helper app called Sungstratum. Sungstratum enabled support for Substratum Themes for Samsung Galaxy devices. Now that Samsung Galaxy S9 and S9 Plus are shipping with Android Oreo, you no longer need the Sunsgstratum add-on. We are going to make use of the Andromeda add-on for Substratum to get the job done!
