 :::tip[What apk should I use?]
 
 **Universal** should work on all devices. If you want a smaller apk, use the one that matches your device's architecture.
+**Legacy** apks are using the `useLegacyPackaging` flag on the build which compresses the native libraries to reduce the apk size. However, this can affect loading performance. Read more [in the android documentation](https://developer.android.com/reference/tools/gradle-api/7.1/com/android/build/api/dsl/JniLibsPackagingOptions#uselegacypackaging).
