How to access engineering mode on an Android

Almost all mobile devices have Android´s operating system. However, there are very few users that know the existence of a hidden menu that contains a wide array of advanced settings that, believe us, will blow your mind.

Don´t you believe us? Let us tell you what it really is. This menu is called “engineer mode” (do not confuse with developer mode), and, with it, we will be able to have access to a series of settings of our device´s components, such as the hardware, sensor, and even microphone configuration, which has a default configuration that can be modified through this menu.

A classic example is the ability to increase our device´s volume to levels way beyond the default maximum volume limit that comes with the basic settings of the device, being able to unlock our phone, among other things.

But the best is yet to come, and that´s what will keep you reading until the very end. You don´t need to be a genius to have access to this mode (even if it seems like it) since most smartphones have MTK model chips. In other words, not only it will be easy to have access to engineer mode, but also you will have to follow the exact same procedure, regardless of the phone´s model.

How to have access to engineer mode if you have a Mediatek-based phone?

A lot of phone brands that aren´t as popular on the market have Mediatek or MTK based hardware, and they have access to engineer mode. But the method to reach engineer mode depends on the developer of the phone.
To enter engineer mode, we will begin by enabling the developer´s menu. This is done by entering on your Android device´s settings, and looking for the option “About this device.”

There, you will see an option that says “information about the compilation number.” To activate developer´s mode (and especially, how to keep it activated,) you will have to click on that option 7 times.

Once you click the option 7 times, a message will appear notifying us that said developer settings have been correctly activated. Then, we will be able to enter engineer mode on the developer´s settings, and you will be done.

But, if that doesn´t work, you will only have to take your mobile device and try one of the following access codes to enter on engineer mode, which are the most common codes:

An important thing that you need to know is that there are many articles on the internet that assert that, to enter into engineer mode, you have to be on root mode on your smartphone. This is false. In fact, to root your phone, you need to have entered into engineer mode beforehand.
