Android Secret Codes – Access Devices’ Hidden Settings in Australia (2024)

There’s certainly no denying that Android is a pretty powerful operating system. Its dominance extends to not only its features and functionalities but also its large market share.

Perhaps, this is why it’s targeted the most by cybercriminals. Perhaps, this is why people install Android VPNs to protect their data and privacy.

Regardless, just like any other tool, Android also has a backdoor created by developers for various purposes. However, these secret passageways cannot be accessed via the usual means, i.e., the available user interface.

You can access the hidden settings through a list of different Android secret codes. If you are a techy and love to explore the unknown, check out the list and see what different codes do.

Caution: Some of the codes mentioned in the blog should be used with caution. Otherwise, it would result in either the loss of data or, worse, broken firmware. Moreover, some hidden settings may contain technical lingos. If you happen to come across any setting that you don’t understand what it does, don’t proceed. At all!
