Don’t tell anyone, these are the secret codes for your Samsung phone. There is no doubt that, nowadays, our mobile devices have a wide variety of functions and options with which we can get the most out of them. In addition, depending on the customization layer itself, we have different features that allow us to make better use of our smartphones.
We have already seen some functions in MIUI, the Xiaomi layer, but also Samsung phones with One UI have certain secret codes that open all kinds of doors to completely overhaul the phone. That is why we have compiled each of these keys that we can enter in any mobile of the Korean firm that has this software layer. And it is that thanks to this, we will be able to use additional features on your smartphone.
What are the Samsung One UI secret codes for?
These keys are known as Samsung secret codes or verification keys. Although in reality, we are dealing with a simple alphanumeric character that can be used on the Korean company’s smartphones.
In addition, to make use of these only we must put the correct order and use the phone app of our mobile device. There is no more secret, well, you just need to know what each one is for and what exactly we can enter in the phone. It is also important to know that these codes are unique and specific to the manufacturer.
So, if you want to enter these Samsung verification numbers in any other mobile that is from a completely different smartphone manufacturer, such as Sony, Nokia, Xiaomi, etc, it will not work. It might even be harmful. Therefore, we recommend you not to use unnecessarily with these codes on other phones because they may alter the configuration of your device.
And the best of all is that thanks to these enumerations we can access settings that are hidden to the naked eye. That is, these are settings that are only available for Samsung mobile devices with One UI. In addition, some of these tools will be diagnostic, so they will be really useful when the mobile starts to act strangely and we do not know exactly why it happens. So it will be a very good alternative to be able to avoid going to a professional at first.
How to get out of these hidden menus?
Generally, it will not matter if we have an older Samsung. If this is your case, we will only have to use the back button to take us back to the dialer app of our smartphone. However, in more modern devices, in which we no longer have the forgotten physical buttons, the truth is that they can be hidden.
If this is your case and, therefore, you can not get to use the virtual buttons to exit. Although, the navigation bar should not be hidden at any time, only when we are performing some other test in these menus. But, if you are in full-screen mode for some reason, do not worry, because there is a very simple way to return to use our phone without any problem. Just try swiping up from the bottom of your phone’s panel. If you still can’t see the virtual buttons, try restarting your smartphone.
All Samsung phone OneUI secret codes
These keys from the South Korean manufacturer are compatible with each of the models of the Samsung Galaxy series. As we were telling you, One UI is a layer that has many secret functions, but these hidden codes are reserved for users somewhat more professionally, especially for those who work in technical services.
This means that we must proceed with caution and not modify any parameter if we are not sure of its operation. And the fact is that these codes, exclusive to Samsung, are complemented by those that are common to all Android smartphones. Therefore, let’s take a look at each of them and see specifically where these codes that we will enter in the default dialer application of our phone will take us. And we will not need to press the call button, because as soon as we write a certain number series, the device will take us to that particular menu.
