If you've been looking for a way to hack your Android device, you've probably come across the term "Apk mod" - modified application package. However, unlike a regular application, a modified version of an app is not created by the creator of the original. Rather, it is a modified version of an app made by a group of coders or a random individual. However, you can still use a modified version of an application if you're really into hacking. A hacker can create a duplicate of a popular application and add additional features, making it available for free.
