Have you ever come across "secret codes" for phones that usually begin with "#"? These codes have been around for a long time and can still be used today to access hidden settings and information. In this article, we’ll explain what these codes are and reveal some of the most important ones.
These codes fall into two main categories: USSD codes and MMI codes. While they might not be particularly useful to the average smartphone owner, these hidden codes can be fun to try out once in a while to satisfy your curiosity. The purpose of this article is to provide a comprehensive list of these secret codes for Android devices.
Before diving in, it’s helpful to understand what these codes are and the key differences between MMI and USSD codes. However, if you're in a hurry, feel free to skip ahead to the section where we explore specific smartphone codes.

I still remember how amazed I was when I first got hold of the Nokia 3210 back when I was a kid, and it was during that time I developed my love for technology, particularly for mobile phones. I started sharing my knowledge through writing in different blogs and forums back in Nokia Nseries era. I even make videos before where I put different phones side-by-side. Today, I'm still an avid enthusiast of smartphones, but my interests have evolved into smart devices and electric vehicles.
How does one go about finding out if there has been any outside influence on my phone?

These were far more useful in the days of dumb phones. With smart phones, this is pretty esoteric or info otherwise available in the app or irrelevant. Most prepaid deals offer unlimited talk and text for the most part anymore.

How much free space does your device have? If it still has, probably resetting it would fix the bug. If you do not have enough free space, try deleting some items or bigger apps.

Windows as your talking about, cannot run on a phone. The architecture is completely different your phone is most likely an arm x86 or in that field and windows cannot run on that by default however there is a version of Windows built for the atom processors which are incredibly terrible in my opinion. However if you would like Linux on your phone there are plenty of ways to get Linux running on your phone

These codes are generic for Android - so for instance a Google device or other devices running the Stock version of Android. Whilst some will work on other devices running a manufacturer version of Android, it's a hit or a miss as to what works.
You can try searching for Samsung specific codes, though again it is not 100% certain that all of them will work. (some may be specific for the Galaxy range, or may change for different years).
You can download apps from the Google play store that aggregate these settings to a helpful UI.
