    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 disabling it 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.

    Android surprises us every day, although observing the development of new features, you may notice that, as it turns out, not available to everyone.

    The creators of the android are trying their best to make their "green little robot" completely safe.

    Unfortunately, many clients are subjected to various tests, and hackers are looking for weaknesses in the phone or system.

    Therefore, the developers gave everyone the opportunity to contribute to the development of interesting and safe features that can improve system performance, and may even extend battery life.

    On phones samsung, xiaomi redmi, meizu, asus zenfone, htc and others running on android 4.2, 4.4 2, 4.4, 4.4 4, 5.1, 5.1 1, 6.0, 6.0 1, 7.0, the default developer mode option is hidden to prevent accidental interference inexperienced user - most are unaware of the potential of the functions available there.

    Most only use USB debugging on their smartphones, although android combined with a properly configured SDK can accomplish a lot, like taking screenshots in situations where the traditional method (using a keyboard shortcut) doesn't work.

    In addition, the user can adjust the animation scale, rotation rendering, set limit background processes, etc., etc.

    The Developer Options option is very useful for programming or just for developers as the name suggests.

    However, it can also make life easier for less advanced but ambitious users looking to tweak their phone a bit.

    How to activate developer mode on an android phone

    In order for you to be able to enter developer mode, you must first enable it. To do this, go to "Settings" and then select information about the device / phone.

    Then go to Software -> Build number and click on it seven times in a row. The device will inform you that developer mode is on (if you press it for the eighth time).

    After that, a new function will appear in the device settings - "Developer options".

    There you will find a fairly extensive list of software options. Here are some of the options for programming on my phone.

    What does developer mode give to android if you switch to it

    If you are a programmer, then, of course, you know what options are needed. However, I think the average user can use at least some of these features.

    USB Debugging mode is most useful for advanced users and developers, but it is not necessary to enable it, although some applications require this mode to be enabled to work properly.

    Even before the advent of Android 6.0, there were a number of improvements in battery life and power management. Making adjustments accordingly helped in some way to extend the battery life.

    If you have problems with offline work, you can check the following method: go to each of the three positions animation scale, animation transition scale, animation length scale and turn off all animation completely.

    Sometimes a very large number of applications are running in the background, which can not only slow down the phone, but also reduce the battery life.

    If you do not want applications to run in the background, then enable the option to disable background applications.

    However, I would like to suggest caution when using this feature, as it may affect the performance of applications that need it (eg Alarm Clock).

    There is also a function to limit background processes. Its main purpose is to reduce the load on the CPU (that is, to increase the battery life).

    Developer options are dangerous

    Above are just some of the functions that you will find in the programmer's section.

    Much of the function is for more complex operations that can damage your smartphone if you don't know how to use them.

    Google hid the programmer panel because hackers do not sleep all the time and try to "break" the android, which can withstand even the most powerful hacker attacks.

    Any actions performed on this tab are only your responsibility, so I advise you to think and be careful.

    How to disable developer options in android

    Disabling software may seem more difficult than enabling it, but in practice it is very simple.

    You need to go to the "Applications" section, select the options (ellipsis) at the top and click reset settings. Don't worry - all your settings will not be deleted, everything will remain as is.

    Then go to the "Memory" tab and click on "Clear data" and "Clear cache".

    After clearing the data, the settings will automatically turn off and you will be taken to the Android home screen.

    Now go back to the settings. You will notice that the Developer Options option is no longer listed. Good luck.

    Android, like other popular operating systems, has its own secrets. Some of them are useful but rarely used. We will tell you about the little-known and interesting secrets of Android.

    Basically, when it comes to android secrets, many talk about some functions that everyone around them knows about. We will try not to go into the usual functionality of smartphones and tablets.

    Engineering codes

    The first and most important secret is engineering codes. They are unlikely to be useful to ordinary users. They are mainly used by workers in service centers when you need to learn something about a device or execute a system command.

    * # * # 4636 # * # * - information and settings;

    * # * # 8351 # * # * - enable recording of telephone conversations;

    * # * # 4636 # * # * - will provide useful data about the device:

    • about the phone;
    • about the battery;
    • statistics and phone and battery usage.

    * # * # 7780 # * # * - will format the smartphone or tablet, but will leave all applications, whether system or downloaded. All files on the external SD card will also remain.

    * 2767 * 3855 # - will completely format the device.

    * # * # 34971539 # * # * - allows you to manage the camera firmware, as well as get information about it. After entering the code, you can choose:

    • updating the camera firmware to an image (do not do it under any circumstances!);
    • camera firmware update;
    • camera firmware data;
    • the number of previously performed camera firmwares.

    * # * # 7594 # * # * - allows you to change the function when you hold down the power button for a long time. In other words, you can assign it to turn off or restart the gadget, turn on / off mobile data, and so on;

    * # * # 273283 * 255 * 663 282 * # * # * - allows you to back up any files on the device;

    * # * # 2663 # * # * - sensor;

    * # * # 2664 # * # * - another sensor test;

    * # * # 0588 # * # * - motion sensor;

    * # * # 3264 # * # * - RAM.

    Developer Mode

    Now let's talk about Developer Mode. You've probably already seen such an item in the settings, but now it's time to look at it in more detail. This mode activates additional functions that are unlikely to be needed in Everyday life... They are mainly used by developers and programmers.

    First you need to enable developer mode. We go into the settings and scroll to the very bottom. We find the item "About device", and click on it several times in a row. The gadget will ask for confirmation to unlock developer mode - press OK.


    Now we have a number of features available, which must be used carefully! They can lead to system errors, which the smartphone itself will warn about. All functions of this mode are presented and described below.

    • Backup password. If you do not want someone else's hands to back up all the files on your phone (for example, after downloading all the data to your device), set a password for use.
    • Active mode. If your smartphone is charging, then it will not go out (of course, if you do not turn it off yourself).
    • Protect SD memory card. All programs will ask permission to use data from the memory card. So, for example, you can prevent a virus from working.
    • USB debugging is needed to perform the interaction of the gadget with a PC.
    • Layout emulation emulates layout.
    • Select the application to be debugged.
    • Wait for the debugger. When the debugger connects, the above application will open.
    • Show touches. Quite an interesting function that shows where you touched the screen. A very useful thing, because with it you can designate touches on the screen and take screenshots of instructions, as we did in the article about.
    • Show pointer location. Displays detailed information about touch and slide on the screen (Location by X and Y, etc.).


    • Show layout constraints. An interesting function with which you can see the size of each item on the screen.

    • Show updates to GPU views. Windows presented by the GPU will blink.
    • Show screen updates. The area of ​​the screen to be refreshed will flicker in bright yellow.
    • Setting up animation. Includes window animation scale, transition animation scale, and apparatus duration scale. Disabling them helps a lot.
    • Disable hardware overlay - Permanent GPU usage for screen composition.
    • Forced GPU processing. Use 2D hardware acceleration in applications.
    • Strict regime. If the process is performing long-term operations on the main thread, the screen will blink.
    • Show CPU Usage - Usage Info central processing unit in the upper right corner.

    • GPU Processing Profile - Measurement of processing time in ASDG.
    • Enable tracing. Includes various traces such as graphics, Input, View and others.
    • Do not save transactions. Delete operations after they have been completed by the user.
    • Background processes. Allows you to limit the number of background processes from one to four.
    • Show all ANR. Show Application Not Responding window for background processes.

    The Android mobile operating system has many hidden features that ordinary users don't need to know about. For example, a smartphone can show the processor and memory load, record statistics on the operation of processes and applications, simulate the operation of the screen in various modes and resolutions, and much more. All of these and a number of other features are available in developer mode on an Android smartphone or tablet. Anyone can enable developer mode on a device, and it's pretty simple to do. In this article, we'll look at how to enable and completely disable developer mode in Android.

    How to enable developer mode in Android

    Most often, an ordinary user in developer mode may need to debug a device via USB if necessary. Below we will provide a standard diagram for enabling developer mode, but note that it may differ slightly depending on the device. For example, on smartphones by the Chinese company Meizu and Xiaomi, the menu items may have a different name or be located in the "Advanced" section, and not directly in the settings.

    To enable developer mode in Android 6.0, 7.1 and other versions of the mobile system, you need to do the following:

    Important: When activating a number of settings in developer mode, the smartphone may malfunction. In particular, there is a possibility of data loss on the device, so we recommend that you be extremely careful to enable or disable various settings in developer mode.

    How to disable developer mode in Android and remove it from the menu

    Disabling developer mode is extremely simple, just go to the "For Developers" menu item in the settings and switch the switch in the upper right corner to the "Off" position.

    But this will only disable this mode, while the section itself will remain in the settings. To completely remove it from the menu, you will need to do the following:


    After performing the above manipulations, the "For Developers" section will disappear from the settings menu.

    Important: Not all models of smartphones and tablets can find the "Erase data" item in the settings. If there is no such item, you can remove the developer mode from the settings only with a complete reset of the smartphone.

    The Android operating system is attractive for its customization. A wide range of customization options for the interface and functions of a smartphone became an additional tool in the Google marketing company in the early stages of Android OS. We have already talked about fine-tuning the Android system sounds in the publication.
    Today we will consider how to open additional ones in your Android smartphone. developer functions by activating the corresponding mode in the machine's system.

    How to enable developer mode on Android

    To enable developer mode on our smartphone, we will perform the following steps:

    1. Open the Phone Settings and find the About phone item. Usually this block is located at the very end of the list of available options. The name of the setting may also differ: Phone details, Information or something similar

    2. Now we need to find the line in which the Build number of our firmware will be registered.
      This item can be directly in the menu About the phone, or can be set in one of the sub-menus, such as About firmware, Additionally and others

    3. The case is small. We need several times (usually 7 touches) in a row quickly tap(click) on the item Build number.
      Just getting started " to tap"with your finger on the screen over the desired item. After 4-5 clicks, a warning pops up with content like: You are almost there. 3 steps left- or something like that. This means that we are doing everything right.


      We do not stop and continue to knock on the screen a few more times. Do not be afraid to miss the notification that the activation of the developer mode was successful, even if you do not have time to stop, unnecessary clicks will not affect the operation of the system in any way and will not turn off the Features for developers.
      Finally, an alert will appear in front of us: You have become a developer!

    4. Actually, that was all that needed to be done. To make sure that functions for Android developers are now available to us, open Settings and look for the corresponding menu item there. It will probably also be located somewhere at the bottom, next to the section About the phone

    How to disable developer mode on Android

    By and large, the presence or absence of an active menu item of functions for developers does not affect in any way standard work smartphone. If desired developer mode can simply be turned off the corresponding slider in the settings of the mode itself

    However, to this paragraph " did not bother my eyes"or in any other case, when it needs to be removed, you can get rid of it completely.
    Logically, it would be permissible to assume that disable developer features Alternatively, you can also multi-tap the Build Number in the phone information. However, it is easy to make sure that this action only works on enable, so when the mode is already activated, we will receive the following notification:

    To disable developer mode on Android you need to do the following:


    What is Android developer mode. Useful functions

    Usually the description of the function is placed at the beginning of the article, in this case we decided to deviate from the rule and make an exception.
    If you've opened developer features with certain intentions, then you can already start implementing them. If you did this in order to expand the general understanding of the system's operation or just out of curiosity, then below we will give several menu items from the functions for developers that can be useful for an ordinary user.


    The rest of the items of functions for developers, in our opinion, are of less interest to ordinary users. But, of course, you can always use those features of the system that most other owners of devices on Android OS do not use.
    Make backups and be careful.
