How to enter developer options for android. How to enable secret settings for Android developers. How to speed up your Android phone

There is one interesting item "For developers" in the settings of your device. With its help, users can customize the behavior of the system, activate any functions, and developers can debug the operation of the desired application / game. For example, in this tutorial we will tell you how to enable "USB debugging mode"(see point 4 in the description of the developer menu functions), an error report is viewed in it, the factory unlock of the bootloader is turned on, and much more.

Despite the fact that all Android devices have the same settings for developers, device manufacturers may place this option in different sub-items of the Settings menu. Now we will analyze exactly how and where to enable / disable developer mode on an Android smartphone or tablet, and then we will tell you what functions and under what circumstances you can use.

How to enable developer mode on android:

For clarity, we have attached a video instruction in which the process of activating the "For Developers" menu is displayed.

If you have developer mode does not turn on on an android device- try pressing "everything in a row" in the section about the phone, in rare cases notifications may not appear, so just scroll through the menu, with a high probability you will find that the developer mode has been activated. Otherwise, indicate the model of your device and the firmware / build version in the comments and we will help you.

How to remove or disable the "For Developers" mode from the settings menu:

It should be noted that some of the devices do not allow this operation, but in most cases the item is hidden in one click.

Go to the menu "Settings", scroll to the point "For developers", go into it and uncheck the box opposite the word "Included"... The device will automatically return to the previous section and the "For Developers" item will disappear.

If for some reason you do not have a checkmark opposite "Enabled", then you should use the following instruction:

Open "Settings" -> "Applications" -> "Settings" -> Then go to "Storage" and select "Erase data, Clear cache". This method is suitable for most smartphones and tablets, so if it helped you, be sure to let us know in the comments to the article.

Next, there will be useful functions and features of the "For Developers" menu, which may be useful in certain situations.

Do not turn off the screen
If this parameter is activated, then the screen of your device will never go out, provided the charger is connected. This feature will be useful for developers of Android applications who are forced to follow their brainchild for a long time.
Also, the function may be needed for social networks, where "live" updates take place and you do not have the time, desire, to constantly press the screen so that the screen does not turn off. Owners of devices with AMOLED displays should be careful, as the so-called "burn" effect may occur on the screen. The image is printed on the display and cannot be removed in the future.
Factory unlocked
Unlocking the bootloader on your smartphone / tablet allows you to use custom recovery and other goodies in the future. For example, on a device with a locked bootloader, there is no way to get into the Android recovery menu and return the system to its original form / install a new OS.

In fact, this option does not allow you to unlock the bootloader, but it does give "permission" to do this with your device. If you do not plan to perform the previously listed manipulations, you should not activate this function.
Running applications
Everyone knows that Windows has a task manager, which displays which processes are currently running. This allows you to understand what is working at a particular moment and why the computer is unstable, which consumes most of the resources. You will not find such an analogue in the standard settings of Android devices, so the "Running Applications" function can be very useful.

You will be able to view which applications are running in the background, for how long, as well as the amount of RAM they consume. Do not forcefully try to terminate running processes, this can lead to unexpected consequences. You do not need to worry, Android has long learned to manage RAM and users rarely feel a shortage of it.
USB debugging mode
One of the few features that developers need in the first place. The main purpose of USB debugging mode is to perform specific actions on your device through the transmitted commands from a personal computer. For example, by connecting to the Adnroid SDK, users will be able to install an application through a computer, get the necessary information and even get ROOT access.
How to enable usb debugging on android
To enable usb debugging mode on an android device - go to the "For Developers" menu, find the "USB Debugging" or "USB Debugging" item and activate it!

Naturally, nobody cancels the usefulness of this parameter, but for safety it is worth turning off the USB debugging mode when you are not using it.
Fictitious location
It's no secret that Android phones and tablets can track by knowing your current location. But surely few people know that Android has a function that allows services, applications to report the fake location of the device. In other words, you should activate the function and then select the program for which the wrong location of your device will be displayed.
Disable absolute level
If you search, you can stumble upon many questions on the network regarding changing the volume of Bluetooth speakers, headsets and other devices using an Android smartphone. For unknown reasons, this does not always work, the sound becomes louder and quieter. If you are faced with a similar problem and would like to get rid of it, then do not forget to activate the "Disable absolute level" function. Otherwise, do not touch this parameter to continue the normal operation of the device.
Visual response
By activating this function, you will see small dots on the screen, allowing you to find out exactly where the press was made. It is useful in several cases: for developers, for people who are experiencing problems with pinpoint movements, as well as at the time of recording video from the device's screen for greater clarity.

In this article, we tried to explain what "Developer Mode" is, how to enable and disable it, and what useful functions you can use without fear of damaging your smartphone / tablet. Of course, there are a lot of other parameters in the developer's settings, but most of them have no practical meaning for ordinary users, but are intended primarily for people involved in software development.

Developer mode, as the name implies, may be needed primarily by developers, but in fact, it is often used by ordinary users as well. For what? Yes, at least in order to. But sometimes there is a desire to turn off this mode and remove it from the menu. How to do it? Let's show an example on a Samsung Galaxy smartphone.

Please note that the developer menu itself has an On / Off switch, but turning it off does not make the section disappear from the settings. Not at all, he remains there, so you need to go the other way.

This path is simple and works great on devices based on Android 6, 7, 8, etc. Go to settings.

Find the section with applications. In our example, it is called that.

Look for the "Settings" line, click on it.

On the application page, open the "Memory" section.

Here you click "Clear data" (do not confuse it with the cache). This button can be located directly on the application page.

Confirm deletion.

The desktop will most likely open. Even if this did not happen, it does not matter, just open the settings and look where the "Developer Mode" menu was - it is no longer there.

Remember that you can turn on developer mode again at any time.

The popular operating system for mobile gadgets Android has extensive specialized functionality that is used by programmers and application debuggers, hardware testers, as well as advanced users who want to get the most out of their device. In particular, the OS provides the ability to display the load on the processor and memory module, to record statistics on the use of individual processes and programs. You can also simulate the screen in a variety of resolutions and color schemes, which becomes a real lifesaver for site testers and other professionals responsible for the usability of applications and network resources. To access these options, you need to enable Android developer mode.

How to do this, as well as how to turn off this environment, we will consider in detail below. The described actions will be identical for almost all devices running Android, be it a top-end smartphone from a well-known brand or a simple and cheap handset from a little-known one.

This is how the Android engineering mod is arranged. The names of the functions may change depending on the version of the system and the Russification package, but their purpose is always preserved.

How to disable Android developer mode

When all the necessary operations are completed, you can exit the environment for developers. To do this, we perform the following sequence of actions:

Open the menu “ Settings"And scroll down to the section" For developers».
We go into it and see a switch at the very top.
Click on it - this turns off the Android developer settings block.

In Android 4.4 KitKat, many noticed that the item "For Developers" was gone. Actually, a similar situation will be with all versions of Android that came out after (and this is currently Android 5.0.1, 5.02, 5.1, etc.).
Thus, if the item "For Developers" has disappeared, then this article will come in handy for you.

How do I return or enable the developer clause?

1) Settings -> About the phone(if the tablet is " About Tablet PC»).

2) Scroll down, you will see an item such as " Build number»

3) Tap on it several times (that is, press, 7 times)

4) A joyful message will appear: “ You became a developer».

Ready!

Now you can go to Settings-> For Developers and enable USB debugging and other useful things.

P.S: item " For developers"Is in the section" System»

Why activate the "For Developers" item?

The most common option is when you get root-rights, you need to enable USB debugging, which is located in the "For Developers" section.

How do I turn off the "For Developers" item?

Settings-> section " System»-> For developers-> Off (top switch).

Thus, you understand why and where the item "For Developers" disappeared and now you know how to return it.

Android Developer Mode is a special set of features that is grayed out and hidden by default. Upon activation, it opens access to a set of auxiliary settings and capabilities. Among them: additional items for working with hardware and smartphone software, tools for debugging, logging, reporting, device diagnostics, etc.

In most cases, the functions of the developer mode are of little interest to the common user, since they are intended primarily for professionals: programmers, firmware developers, application creators and service center masters. But sometimes an ordinary user also needs to use the developer mode. You cannot do without access to the functions hidden in this section, when necessary, to allow unlocking the bootloader or (for example, for). And how to activate this mode and get into its menu, read below.

How to enable developer mode on Android

On Android 4.1 and below, the "For Developers" item is located in the settings menu. In newer versions of the OS, it is hidden by default.

To activate it, starting with Android 4.2 and ending with Android 7.1, go to the settings and find the "About phone" section (at the end of the settings menu). Find the item "Build number" there and quickly click on it 7 times in a row.

A message will appear on the screen telling you how many times you have left to click. Continue until you see the "You are now a developer!" Notification.

After that, the "For Developers" section will appear in the main settings menu.

How to activate the item "For Developers" on Android 8 and 9

On Android 8.0 and newer, to enable the developer menu, go to the System section (the last item in the settings menu). In this section, find the sub-item "About phone" (also at the very bottom).

By clicking on the "Build number" line 7 times, you will receive a notification that you have become a developer.

The "For Developers" item will appear in the "System" section of the main settings menu.

Developer mode in MIUI on Xiaomi

In the MIUI firmware on Xiaomi, the developer menu is activated in a similar way. The item "About phone" is the first in the settings menu. Go into it and find the "MIUI Version" parameter. Having quickly tapped it 7 times in a row, the notification "You have become a developer!" Will appear on the screen.

After activating the mode, go to the main settings menu and find the "Advanced settings" item (in the "System and device" group) there. The menu "For Developers" is at the end of the list, this is the third item from the bottom.

Overview of Developer Menu Features
