I’m still not aware of any specific term or acronym “SoSOMod APK” in my knowledge base as of September 2021. However, it’s possible that “SoSOMod” refers to a modified or customized version of an Android application (APK).
Many apps have modified versions (often referred to as “mods”) created by third-party developers. These mods can offer additional features, enhancements, or changes to the original app’s functionality. They are typically not available on official app stores like Google Play and are downloaded and installed manually.
