Snapchat is testing a new much faster and smoother Alpha UI and here's how you can enable it with ROOT

Snapchat users on Android were all complaining about how slow the app is. Looks like finally, Snap Inc is working on a much faster version of the app and here is how you can enable it by yourself. Be sure to have root on your device and follow the steps carefully.

How to enable the new Mushroom UI

Get a root-enabled file manager. We recommend MiXplorer or Solid Explorer.
You must have Snapchat v10.39 or 10.39.1.0 beta or higher.
Open MiXplorer and tap on 'Root' in from the side panel.
Navigate to /data/data/com.snapchat.android/shared_prefs and look for a file named 'dynamicAppConfig.xml'.
Open the xml file and look for a line containing this string:

<string name="appFamily">snapchat</string>

Change the 'snapchat' value to 'mushroom'. The string should look like this:

<string name="appFamily">mushroom</string>

Now you need ADB or a terminal emulator app.

Enabling via ADB

Connect your phone to your PC and enable USB Debugging in Developer Options if you haven’t already.
Download and install the latest ADB binaries on your PC if you haven’t already.
Open up a command prompt on your computer in the same directory where you saved the ADB binaries and enter the following command to enter ADB shell:
Windows Command Prompt: adb shell
Windows PowerShell: .\adb shell
macOS/Linux Terminal: ./adb shell

Now, enter the following 4 commands one-by-one (After entering ‘su’ you will be asked to grant root access)
