IoT Hidden Menu: What is it on My Phone?

IoT Hidden Menu is kind of a secret setting that pops up when you dial some code on your Android phone. Since the beginning of Android, these types of hidden options, also known as easter eggs have been the part of the OS that we can still explore by performing a set of actions on particular marks. By default, these underground options have been added for Android users to explore and take advantage of in need.

The fact is massive users of Android still aren’t familiar with the IoT Hidden Menu and how they can access it. Even it has been available for ages, it still contains some fascinating options and also helps find hardware faults. In this article, we will uncover everything about the IoT Hidden Menu including the secret codes that perform specific tasks when you dial them. Sounds exciting? Let’s begin.

What is IoT Hidden Menu?

It is one of the easter eggs on Android that when uncovered, we get to see a couple of unique options mainly related to checking device condition. For checking device hardware faults, there are color and touch testing options for display, vibration testing, receiver testing, speaker testing, and more. Each of the hardware tests lets you thoroughly check for defects i.e For testing display touch, it tells to tap on different area on the screen.

Also, there is a Sensor option which is incredibly useful because it shows the available sensors on your phone as well as their second to second stats. This way, you not only get to know how many sensors and what sensors your phone has but you also get to see whether they are working appropriately. Apart from these hardware diagnostic options, the IoT Hidden Menu also contains some system modification options such as Factory reset, Advance Network setting, etc.

The availability of these options under the IoT Hidden Menu can vary from device to device. Most of the options that we mentioned will be found on the majority of the latest Samsung Android phones. You can type *#0*# on the dialer on your phone to access the menu. In other Android phones, if nothing happens when you dial the code then it is likely that your phone doesn’t have IoT Hidden Menu enabled.

IoT Hidden Menu Features

Before you get your hands on this secret setting, you probably want to know the features that it provides. Well, we have listed all the features below that are found in the IoT hidden menu.

Red, Green, Blue. As soon as you unleash the menu, you will see these three options in the top row. These are helpful for checking whether color is properly appearing on the display. Upon clicking on any of them, your phone’s display will get completely covered with that color. Hence, you will be able to find pixel stuck type of issue if there are any on your phone.
Receiver. It is one of the component on your Android phone that allows you to send or receive Android system or application events. By clicking on Receiver, an unknown sound will come out from your phone’s earpiece. If that happens, it means the receiver is working fine otherwise it is faulty.
Vibration. Using this option, you can test the vibration on your Android phone. Upon clicking on it, your phone’s vibrator should be activated.
Mega Cam. It will turn on the back camera with real HDR auto flash On and help you test the back camera performance.
Gripsensor. It is one of the sensor on your phone that indentifies your physical touch i.e when you hold your phone. You can tap on it and hold your phone on hand to test whether Gripsensor is working okay.
Sensor. This option will give you raw data about all the sensors on your phone including their stats of every second. You can also see some visual graph of accelerometer sensor as well as image test. In image test, you’ll be shown a picture of a dog.
Touch. It will let you test display touch of your phone. Too many square boxes will be displaying that will turn green when you touch them. While you will be touching boxes, your finger’s movement on the screen will be highlighted with a black line.
Speaker. Before you click on it, be ready to hear a beautiful song that you must have never heard before. This option basically lets you test the speakers of your Android phone.
Sub Key. It allows to check whether your phone buttons i.e Volume up, Volume down, Power key are working fine. When you run this test, initially your phone will be displaying black color and will change upon taping buttons. If screen color changes upon clicking a button it means that the key is in working condition.
Front Cam. Similar to the mega cam test, Front Cam option will let you test the performance of your phone’s front camera. When you run the test, the front camera will open with HDR Auto and flash ON (If your phone has it). After that, you can take a selfie to complete the test.
Black. When you are in doubt about the black color appearance on your phone’s display is somewhere not usual, you can run this test to check.
Version. This option will reveal the phone model and some other hardware details that aren’t much interesting or useful.

All these options will be found under the hidden menu in the latest Samsung Android phones. In old models, you might see some additional options such as Factory Reset, Network Tweaking setting, etc. These options no longer come in new models as these were not helpful and benefiting users hence Samsung removed them.

Also, unlike the usual Factory Reset, if you click on Factory reset option under the hidden menu, it will immediately wipe out all the data on your phone without asking for confirmation. So, be aware of this before you click on Factory reset from the hidden menu.
