From time to time, modern users wonder how to enable Android developer mode. Doing this is much easier than it looks. Using this menu item, you can find some hidden functions of the mobile device. Next, we will tell you all about how to enable and disable the study mode in your phone.

Mode Description

What is developer mode?

This state of the mobile phone is not so important for ordinary users. It allows you to debug the device via USB, find out information about the memory and processor, and also see application statistics.

However, sometimes this state is extremely useful. But how to enable android developer mode? Every modern person can do this. Usually, the procedure does not have any features. But there are some secrets you need to know.

Up to version 4

How to enable android developer mode? In older builds of the Android operating system, the user can bring the idea to life using a special button.

You will have to do approximately the following:

  1. Turn on phone.
  2. Open the main menu of the device.
  3. Enter the "Settings" section.
  4. Click on "Developer Mode" or "Hidden Settings".

Fast, simple, convenient. But such a scenario in modern phones is almost never found. And so we have to act differently.

Source of problems

How to enable android developer mode? For some time now, the corresponding menu item has not been available in the operating system of the phone. But this does not mean that it was completely removed.

It is because of this phenomenon that users do not know how to act. Following the instructions below, a person will be able to quickly cope with the task.

"Android" 4.2.2

The developer menu, as we have already said, has ceased to be displayed for some time now. Particularly attentive users could notice such changes already in Android 4.2 Jelly Bian.

To return this component, you can act like this:

  1. Go to "Settings" on your mobile device.
  2. Open subsection "About phone".
  3. Scroll through the menu that opens to the very end. We need the "Build number" item.
  4. Tap on the area under the inscription "Build number" several times. To be more precise, you will have to click on it about 7-8 times.

Already after 4 taps, the user will see a message that will say how many clicks the studied menu will turn on. Ready! Now the "For Developers" section will appear in the settings. He is what we need. From now on, it is clear how to enable developer mode in Android 4.2.2.

After 5.0

In new versions of "Android" there is also no studied menu item. And it's not hard to get it back. The main thing is to know how to act in this or that case.

How to enable developer mode in Android 5.1? The following guide will help you cope with the task:

  1. Get started with your mobile device.
  2. Open the main phone settings.
  3. Enter the "About device" section.
  4. Find "Build Number".
  5. Tap on the corresponding line about 5-7 times.

In general, the algorithm will be exactly the same as in the previous case. After the done actions, the user will be able to see the "Developer Options" section. In just a few minutes, it will be possible to bring the idea to life.

After the 6th

And how to enable developer mode in Android 6.0? To do this is not difficult. Especially for those who have already worked with the studied mode on older versions of mobile OS.

The fact is that, in general, the instruction will not differ much from the previously proposed instructions. In general, the algorithm of actions is as follows:

  1. Open "Settings" in the main menu of the mobile device.
  2. Visit the "About phone" item. On some devices, this section is called "About device".
  3. Find "Build Number".
  4. Tap on the corresponding menu item about 7 times.
  5. Return to the "Settings" section.
  6. Open the sub-item "Advanced".
  7. Go to the "Developer Mode" menu.

That's all. From now on, it is clear how to enable developer mode in Android. This is one of the simpler procedures that every modern user should be familiar with.

Xiaomi and mode

It is worth paying attention to the fact that the listed instructions may differ slightly from each other. It all depends on the specific mobile device. A number of items are signed differently.

For example, as we have already said, somewhere the "About phone" section is called "About the device. On Xiaomi smartphones, there is no "Build number" item. Instead, you can see "MIUI Version".

Accordingly, you will have to repeat all of the above actions using this menu item. Otherwise, the proposed instructions are no different from the instructions we have previously studied.

Version 7.0

How to enable developer mode on Android 7.0? A similar question arises in many modern users. After all, operating systems are being improved, finalized and changing their "appearance".

To bring the idea to life, you will have to use the instructions for Android version 6.0 and higher. It is these instructions that work on new versions of the operating system. There is no difference in them.

Tablets

How to enable developer mode in Android 6 (and beyond) on tablet devices? Is it possible to complete the task at all?

Yes. Tablets also allow you to enter the developer menu. To do this, you will have to follow the previously suggested instructions. But with some changes.

Namely - in the device settings you will need to select the "About the tablet" section. It serves as a replacement for the "About phone" option. Otherwise, the instructions for enabling developer mode remain the same. It varies slightly depending on the version of the mobile device.

Disable mode

We figured out how to enable Android developer mode in one case or another. How can I disable this section? Everyone should also be aware of this. After all, an inexperienced user is able to damage the operating system of the device with their work in developer mode.

To deal with disabling the mentioned option, you need to:

  1. Go to the main settings of the gadget.
  2. Open the "Additional" section.
  3. Select "Developer Mode".
  4. In the upper right corner of the screen, move the slider to the "Off" state.

After the above steps, the studied mode will not disappear - it will still remain in the phone or tablet settings. However, the parameter will not work temporarily.

In order to re-enable the developer mode, you just need to move the toggle switch to the "On" state. Fast, simple, convenient!

Finally

We have figured out how to enable developer mode in Android. Getting the job done is easier than you think. Even a schoolboy can do it. Just a few minutes and it's done.

But it must be remembered: the developer mode in the inept hands of the average user is doom for the modern gadget. Therefore, if a person has turned on the corresponding menu item, it is recommended to switch it to the "Off" mode. So it will be possible to secure the OS from unnecessary operations and changes in system settings.

Many computer games have cheats that can be entered to make the gameplay much easier. However, a much more interesting feature is the developer mode. It is not available in every game, but if it is, then you can be sure that you will not need any cheats. Naturally, you will first have to figure out exactly how it can be enabled, since each game has its own way of doing this. This article will show you how to enable developer mode in Undertale. This game is very popular, so many gamers ask online about this mode. Therefore, you should read this material in order to save yourself from having to look for answers on the net. You can be sure that after reading this article, you will find the answer to the question of how to enable developer mode in Undertale, and you will be able to use it freely.

What is this mode?

Before you learn how to enable developer mode in Undertale, you should understand what developer mode is in general in PC games. It is used by the creators of the game to test the gameplay and various features of the project, while not spending a lot of time on it. That is why most computer games do not have such a mode. Developers delete it before releasing their project for sale. However, in some cases, they simply block it, and if you find the appropriate way, you can unlock and use it. As a matter of fact, talking about this is the purpose of this article, in which you will learn how to enable developer mode in Undertale.

Turning on the mode

So, if you are wondering how to enable developer mode in Undertale 1.0, then you should understand that for this you will have to change the game code in the root files. So if you don't understand programming at all and don't want to mess up anything, then you better look for the person who will do it for you. However, the process is so simple that you really have no reason to be afraid of anything. All you have to do is find the data.win file, which contains some rather obscure code. You do not need to understand it, just find one line: in the old version of the game it is 00752B20, and in the new one it is 00725D8C. This line of code has a default value of 00, and your task is to change this value to 01. After that, save the file and run the game. Now that you know how to enable developer mode in Undertale, you won't need cheats.

What does it give?

In the game itself, the mode does not need to be activated. You just need to remember the buttons that interest you and use them. For example, if you press the G button with developer mode enabled while in the store, you will receive five thousand coins. Almost every key on the keyboard in this mode has its own function, so it's worth spending a little time to figure out the possibilities that are now open to you. Moreover, there are even combinations such as R+6 or F+6. Such combinations are responsible for teleporting the character to a specific location in the game world, so they can also be useful to you.

Developer Mode is a hidden feature found on Android smartphones and tablets for programmers and developers. In this mode, a ton of various settings and features are available. Learn more about the most interesting features.

Total smartphone optimization

More recently, experts have found several interesting features in the developer mode that allow you to double the speed of the gadget and extend its operation time.

Previously, such a “trick” was hidden from the eyes of most Android users, now experts have shed light on the possibility of optimizing the gadget.

In order to start the developer mode, you must:

  • Go to the "Settings" section of Android.
  • Find the item "About device", click on it.
  • Go to the "Build Number" option.

As a result of the above actions, a solemn notification “You are now a developer” is displayed on the screen. After that, you need to exit the "About device" section and go to the "For Developer" tab.

Now, in order to optimize the performance of the gadget, you need to set the value “0.25 px” or “0.5 px” in the “drawing” or “drawing” parameters, after which you need to restart the smartphone.

According to the promises of experts, the speed of the smartphone after such simple manipulations will double, and the battery savings will increase by 10%.

Backup Data Protection

In developer mode, a useful feature is available that allows you to set a password to protect backup data from unauthorized access. To enable this feature, you must:

  • Open the option "For Developers" item "Password for backup".
  • Enter a new password on the second line, and then confirm it by entering it again on the third line.
  • Click on the "Save Password" button.

To remove the password, just open the above item, enter the current password in the first line, but leave the second and third untouched.

Detailed report on the use of WI-FI connection

In developer mode, there is an extremely useful feature that can certainly be useful to thousands of users, because when distributing WI-FI in Russia, you can often encounter problems at various levels of the OSI network model.

To monitor and save data on various WI-FI connection parameters, there is a Wi-Fi Log function. You can launch it in the "Networks" section ("For Developers" options).

USB configuration

A useful feature that allows you to set the connection mode of your smartphone to a PC without connecting it directly via a USB cable. This setting can be useful when you need to set the "Charging" mode, but the notification does not come when you connect the phone to the PC.

Entering text

For those who shoot overviews, tutorials and other videos using screencasting, the Visual Response feature will be useful, which allows you to position the cursor in those parts of the screen where the click was just made.

The "Show wishes" option allows you to visualize taps and gestures on the screen.

Drawing

In the range of possibilities of the "Drawing" option, there are not only functions that allow you to speed up the smartphone, but also options that provide various conveniences.

For example, the settings for highlighting the window when they are updated, framed in the “Show surface update” item, can be useful when notifications arrive, when they are not only displayed in the status bar, but also make the screen flash completely.

Hardware accelerated rendering

Multiple sampling of screen smoothing allows you to get a better picture. It is activated in the "4x MSAA" option, but do not forget that this function will be useful for high-performance devices, in other devices, an increase in anti-aliasing will only slow down the smartphone.

Useful video:

Android Developer Mode is a special set of features that is grayed out and hidden by default. After activation, it opens access to a set of auxiliary settings and features. 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 a simple user, as they are intended primarily for professionals: programmers, firmware developers, application creators and service center masters. But sometimes the need to use the developer mode arises for an ordinary user. It is impossible to do without accessing 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.

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

A message will appear on the screen, in which it will be written how many times there are left to click. Continue until you see the notification "You are now a developer!".

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 later, 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 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. By quickly tapping on 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 there (in the “System and device” group). The "For Developers" menu is at the end of the list, it's the third item from the bottom.

How to force all applications to use multi-windows

Android 7.0 introduced native multi-window mode, but not all apps support it. In fact, many applications don't support it, so it's not very useful. But you can force the app to be compatible with the new feature and all you have to do is go back into the secret developer settings.

  1. Follow the steps above to enable developer mode
  2. Open Settings > Developer Options
  3. Scroll down and select Force activities to be resizable(Force apps to resize)
  4. Reboot your phone


Now you can open any application in multi-window mode. It should be noted that some applications may force close when you put them in multi-window mode. Apps that don't support it will say "This app can't run in multi-window mode," but most of them still work fine.

Secret Developer Options is one of our favorite things about Android. The average user is not aware of this, but enthusiasts can use them to push their phones to the limit.

Developer Mode is a Pandora's box that opens up the control possibilities of the Android operating system. Of course, the developer mode is an indispensable tool for the Android application developer, but ordinary people can also use some tricks.

We will tell you about five useful features of the developer mode on Android.

How to Enable Developer Mode on Android

Developer mode is a special section in the mobile device settings menu, which is not active by default. To activate the menu, you need to go to "Settings" - "Information about the phone" and click on the inscription "Build number" several times until a notification appears that the developer mode has been activated. After that, you can return to the main settings menu, where "For developers" will appear in the "System" section.

1. Disable animation

You can turn off animations completely, thereby making app loading as fast as your smartphone hardware allows. In addition, you can make the animation twice as fast or turn it off completely.

To change the animation speed, or turn it off, you need to go to the developers menu and find options such as "Window Animation", "Transition Animation", "Animation Duration". If you want to speed up the animation, you must select the "0.5x" parameter. If you want to disable animation completely, select No Animation.

2.4x MSAA

This option allows you to improve the quality of graphics in OpenGL ES 2.0 games and applications. I noticed that a smartphone with the option enabled gets better performance and also consumes more battery power. However, if you need high quality in games and applications, then the 4x MSAA option will improve the image with Multi Sample Anti-Aliasing 4x pixel anti-aliasing.

3. Enable USB Debugging

This is one of the most used options for developers. This feature allows programs on your computer to access your mobile device via USB. In addition, USB debugging is used for recovery, rooting, unlocking, creating a backup on the computer, and more.

4. Backup password

If you want to back up your smartphone, it is highly recommended to protect it with a password. This option encrypts the copies so that an unauthorized person cannot access it unless they know the password. To create a password, click on the line "Password for backup" and enter your password.

5. Use a dummy location

Under the Debug section, there is one option called "Select Application for Mock Locations". To use this feature, you need to install the Fake GPS Location application, which will simulate the location of the smartphone in a fictitious location.

Once you select the app, you can go to Google Maps and check the location of your smartphone. So you can take beautiful photos on Instagram or Vkontakte with location in Hawaii or Paris.

No modern operating system for portable devices can compete with Android in terms of settings and customization options. No wonder, because in the OS from Google you can configure absolutely everything, any little thing.

However, many users are not aware that a huge number of features of their Android device remain hidden. We are talking about the ability to debug the device and some other features that are only possible in "developer mode", which in most cases is disabled and hidden from the user's eyes. We will tell you how to enable it and what features it provides in this guide.

After activating this mode, a new section appears in the Android settings menu called "For Developers". It opens up new possibilities for the user. Some of them, which can be useful even for a simple user, we will consider below:

  • Log buffer size - provides the ability to select the amount of memory;
  • GPU acceleration - activates the processing of two-dimensional graphics;
  • Show CPU usage - displays a screen with information about the current CPU usage;
  • USB connection – selection of the device operation mode when connecting it to a PC via USB;
  • USB Debugging - Enables debug mode when you connect your Android to a PC with a cable.
  • Fake device location - allows you to make applications "think" that you are in another part of the world.

Activation

Enabling developer mode is easy. For this you need:

List of available settings

Now let's analyze the functions of the section for developers in more detail.

Be careful: when working with the settings in developer mode, due to the inexperience of users, the device may fail and even data may be lost. Therefore, it is recommended to enable and disable certain features with caution.

  • Create a bug report. The option is intended for sending error reports. Files for sending are created within a couple of minutes.
  • Backup password. This item allows you to use ADB to create a backup of data on a PC. To create a copy, a mandatory password is required.
  • Active mode. If this option is enabled, the screen of the device will not turn off when it is connected to a PC. It should be used with caution, as prolonged use of the screen can ruin it.
  • Selecting a working module. Tool to select ART or Davlik. You shouldn't change anything if you don't know what they are for.
  • Enable HCI Bluetooth Operation Broadcast Log. This feature is only useful for developers as it allows you to intercept and parse Bluetooth packets. After enabling this option, packages will be saved in the "btsnoop_hci.log" file. The file can be opened and analyzed with Wireshark or similar.
  • Process statistics. Shows information about the processes that are currently running on the device. It is of no use to the average user.
  • USB debugging. Allows you to connect your device to PC via ADB.
  • Revoke USB debugging authorization. When debugging a device via USB for the first time, it needs to be authorized using keys for this. With this setting, you can undo this action and repeat it again.
  • Bug reports. This option is very useful for testing applications. By holding down the power button, you can collect and send crash and error reports.
  • fictitious locations. Allows you to manually set the location. Used by some developers to test geo-referenced applications.
  • Debugging applications. You can manually set applications for debugging. Helps developers to ensure that the application code works correctly.
  • USB check. Using this option, you can scan applications installed via ADB and detect malicious activity.
  • Touch display. If the option is activated, visual effects will appear on the screen, showing touches on the screen.

  • ANR display. Enables the display of system messages when applications freeze. Useful if applications conflict with each other.

Deactivation

This process is also quite simple to complete. On some devices, you just need to find and open the section in the settings menu. "For developers", and in it move the switch to the "Off" position. But in this way, we will only turn off this mode, that is, it will still remain in the settings. And again, make a reservation, this feature is not available on all devices.

To completely remove the function from the menu, you must do the following:

Conclusion

Of course, most of the users do not need the settings described above at all. If you don't understand options well and don't understand what they are for, it's best to leave them alone and don't change anything. Remember, developer configurations are not just hidden from mere mortals. Use them wisely.

The developer options on an Android device can bring a lot of useful settings and display a whole bunch of useful information about your device. For example, in order to adjust the volume of your favorite gadget, you will also need the "For Developers" menu.

Basically, all new smartphones and tablets out of the box do not provide open access to this menu. In this case, we need to figure out how to enable it.

How to Enable Developer Options on Android

1. Go to the general "Settings" of the device and look for the "About phone" section below:

3. After a quick click on this item, the system will give you the following message: "You have become a developer!". Visually it looks like this:

4. Now you can return to the main "Settings" of our Android smartphone or tablet and see the long-awaited "For Developers" menu. We have successfully activated or enabled it:

This completes the procedure for enabling this menu.

Now let's assume that we want to lend our apparatus to someone and are afraid that no one there will change anything serious without our consent. Then this fad "For developers" is better, of course, to hide or disable

How to Disable the Developer Options Menu on Android

Disabling or hiding (hide) the developers menu on Android can be as easy as activating it.

1. Again we go to the general “Settings” of the device and find the “Applications” section there:

2. After opening this section, go to the "All" tab:

3. Then you have to find the "Settings" application there and tap on it once. The following context menu should appear:

4. Click on the button "Erase data" and that's it. The "For Developers" menu has been successfully disabled, hidden or deleted if you like. You shouldn't be afraid of it.

Of course, the system will warn you that "All data of this application will be permanently deleted, including all files, databases, settings, accounts, etc." I have not noticed anything like this on my smartphone. Everything remained "as it was."

Operation completed successfully!
