Do you want to discover some secret Android codes and what are their uses? If so, this article is for you!
Why do Android phones have secret codes?
When manufacturers process their electronic products, each product must go through quality control, where the devices are tested and analyzed. This is done to ensure that the products pass the quality standard set by customers, companies, or manufacturers.
But that is not all.
When it comes to Android devices, especially smartphones and tablets, they undergo various performance tests to make sure that the product works and has no problems.
The downside is ...
It will take a long time and the sources will be limited if they do not have any special means of proof. Therefore, "Android Secret Codes" exist for this sole purpose.
With these or hidden menus, you can make your Android phone perform certain tasks. Furthermore, you can also use these codes to verify various information about the device.
Sounds great, right?
So if you're here for those reasons, then you're in luck. We list a ton of dialer codes and all Android secret codes, common codes, hidden menus, as well as Samsung secret codes and HTC secret codes regarding Android diagnostics.
However, you should keep in mind that:
Some of these codes are universal, while others are not. Making some of the codes useless for some phones, while others are exclusive to specific manufacturers.
Also, it is better to remember that some of these codes can erase your entire smartphone and factory reset it. Oh!
• Be careful and read the description.
• What are the USSD and MMI codes?
• The USSD and MMI codes are Android codes that begin with a hashtag or pound symbol. These symbols are updated as Android releases a new version. Also, some smartphone manufacturers have their own USSD and MMI codes.
Typically, USSD (Unstructured Supplemental Service Data) codes are used to communicate with a smartphone and a mobile network operator. This means that for USSD codes to work, you must always be connected to your provider.
MMI (Man Machine Interface) codes, on the other hand, allow you to access interesting information about your smartphones, such as IMEI number, hidden menu, repair services, and more.
