3 Hidden settings that you should know on your samsung mobile yes or yes

One UI, Samsung's customization layer, is not characterized by being a simple layer precisely. In addition to Android's own functions, the South Korean company's mobiles have endless functions that allow us to expand the possibilities it offers us. But these functions are not always visible to the user. Some are hidden and others directly require the activation of a series of settings. This time we have compiled some of these hidden settings to activate on a Samsung mobile, regardless of the system version or device model.

Hardware Test Mode, the menu that allows us to detect mobile errors

There is a way to check the operation of the various components of the phone. The speaker, the screen, the proximity sensor, the fingerprint sensor… This is especially useful to detect, for example, dead pixels on the screen or to check the status of the touch panel.

To activate this menu we will have to go to the Telephone or Calls application and then enter the following code:

• * # 0 * #

A menu similar to the one we can see in the image below will automatically be displayed:

Within this menu we can test any component of the phone through a series of tests. In the event that any of the components of the component device show any type of failure, it is best to go directly to the official Samsung technical service.

There is another way to activate this menu and it is by using the Samsung Members application that we can download from the Google store. In the Diagnostics section we will find an option called Hardware Test.

Developer settings to extend system functionalities

A menu that is not exclusive to Samsung mobiles, but has been on Android since the first versions of the system. Thanks to this we can alter aspects such as the speed of the animations or the positioning of the GPS sensor. We can also detect hidden Bluetooth devices and even change the resolution and DPI of the screen.

The way to activate this menu is as simple as going to the settings application, specifically the About phone section. Then we will go to Software information and finally to Build number. To activate the Developer Settings we will have to press a total of seven times on this option.

Now we just have to go back to Settings and slide to the last option, which will correspond to the settings we have just activated.

BatteryStatus, the menu that allows us to calibrate the battery of a Samsung mobile

The last hidden setting that we are going to talk about is called Battery Status. As its name indicates, it is a menu that gives us all the information regarding the status of the battery and the voltages currently handled by the motherboard.

If we have knowledge of electronics we can detect possible battery and charge failures, although the most interesting thing about this menu is the possibility of calibrating the battery. To do this, we will go back to the Telephone application and immediately enter the following code:

• * # 0228 #

Next, the phone will show us a menu similar to this:

Finally, we will click on the Quick Start button to start the battery calibration. What this option will do is compare the battery voltage and amperage with the Android logs. If the entries do not match, the system will change the remaining battery percentage to the actual percentage. During this process the screen is likely to turn off several times, yes.
