This item is in the settings.
Initially, it was intended as a tool available only to developers of applications, games and services for this gadget, and necessary only in the course of their work.
It was assumed that in this way the developers get access "inside" to make changes to it that will not affect the work process.
But soon ordinary users appreciated the convenience and functionality of such a utility.
A number of performance issues have been identified that this feature can address. Therefore, at this moment, the service is suitable for performing a number of tasks:
- Getting root;
- Recovery;
- Changes in the features of the operating system, its modification.
The service is quite functional and easy to use.
In what cases may be required? It allows you to get a number of options:
Such a diverse application is very convenient, and allows you to solve a number of problems, the most important of which is the preservation of this information from a non-working device.
Advice. For normal operation via PC, you need to download adb utility, which makes it possible to control the operating system on Android from a computer. Moreover, the program works, both with the help of a graphical interface, and with the help of the console and command input panel, command line
In order to actively use this function, you must first enable or activate it. This needs to be done differently different devices Oh.
Android 4.1 and earlier
To do this, follow the algorithm:
- In versions up to Android 4.1 inclusive, developer settings are visible in free access. They are located in System settings. And exact location there is no location for this menu item - it can be located both in the general list of settings, and in the main menu or in the Applications section;
- After the item is found, check the checkbox next to it;
- A pop-up warning window will appear small size. It will require confirmation that you understand what harm you can do if you do not know how to work with her. Confirm permission, click OK.
Android 4,2,2 and above
In newer versions of the operating system (4,2,2 and higher), this section has been removed from free access. Although it can still be found, turned on and activated. It will just be a little more difficult to do so.
To access the service, use the following algorithm of actions:
- Open the Settings section on your mobile;
- Go to the section "General";
- Go to the section called "About the device";
- Find an item Software and information, and click on it;
- Scroll through the information to the line containing the build number;
- Select this line and quickly touch this line seven times in a row;
- A dialog box will pop up, in which it will be written that you have received developer status and can make changes to the operating system;
- Return to the General section;
- Note that it now has a section Developer Options.
Check the box after that. Now you have
Android is the most open system compared to competitors. However, in order to make changes to system settings and potentially dangerous actions require the so-called ROOT rights.
There are many options for accessing these rights, but most require enabling USB debugging mode. The debug service is abbreviated as ABD. What is it, how to enable it and what advantages will it give root usage rights described in this review.
Why use USB debugging mode?
The mode was conceived by the developers of the operating system for the convenience of end customers, the user can check the operation of various applications and the entire system. Monitor emerging problems and failures, manage the device without restriction, and perform many more functions.
How to enable USB debugging?
Smartphones and tablets with installed system Android is put into debug mode in the simplest way: you need to go to the menu and select the "Settings" item. But further options for its location are possible. Consider the five main locations for this option:
- activate the menu, select the item "Settings", then "Development", then find the line "Debugging via USB" and activate this item;
- for devices with old Android OCs up to 3.0, the activation option through the menu, the “Settings” item, then we find “Applications”, again look for the “Development” submenu, which already contains the familiar line “USB Debugging”;
- if the previous tips did not fit, then we try to go to the menu, the “Settings” item, we find the line “More ...”, then “Developer Options”, in it the cherished “USB Debugging”;
- on Android OS 4.2 and older - menu, "Settings", then "System". In this section, we need the line "About the smartphone (tablet)", here we are looking for "Build Number", you need to click on it ten times, then go to "Settings", then to the "For Developer" section and select "USB Debugging"
Information for users of OC Android 4.2 and older.
For more early versions OC You can skip this step and go directly down the list. After successfully activating USB debugging, the first time you connect to a PC, enter any command or start the procedure for obtaining " super right”, the device displays a dialog box for a trust request. So that when reconnection did not display such requests, immediately check the box "Always allow debugging from this computer".
The device was not detected in Windows.
You need to start by checking the drivers, if they are installed correctly and work correctly, you need to reinstall them, or select the update option. It is important that the gadget be unlocked at the moment the cable is connected. If it is blocked, please unblock it first. Same for correct operation devices to be used usb ports version 2.0, the more advanced version 3.0 present on modern laptops not recommended by the manufacturer.
What if you don't have a USB cable?
Wireless connection is also supported. WiFi networks, which is now very widespread among users. To connect, you need to know the device port and its IP address. The easiest option to complete these steps is to download the ADB Wireless program, which is available for free on Google Play.
Download and install the application, and then run it. A red button will appear in the main window, click on it, and wait for the connection process to complete. At the bottom of the screen, information will be displayed in the following form: abd connect (IP address of your device).
On the computer, start the command line mode. On different operating systems, it is located a little differently, but usually you need to click on "Start", then "All Programs", then "Accessories" in it will be "Command Prompt". We hammer the abd connect command into it (the IP address of the phone or tablet). When entering a command, be careful about the dots and numbers of the address. After a successful connection, you can use all the ADB mode commands.
Help on the capabilities and commands of this program can be found freely available on the Internet, thematic forums describe in detail how to type commands and what actions they perform with the device.
When working with commands in these modes, remember that you can inadvertently delete all user data from the phone. We recommend that if the device contains important information for you, make a copy or move it to a spare memory card. It is very disappointing to lose all the photos or favorite compositions that have been collected for a very long time.
Most people use their tablet or phone "as is", not noticing various inconveniences in their work or simply putting up with them. However, quite big category users tries to modify to suit their needs or to be able to freely manipulate data and settings. Another category - workers service centers. USB debugging is a method for those who want to get to know their tablet or phone better. Make adjustments, changes, diagnose problems, and so on.
Everyone is a little familiar with the principle of building an operating system. It should be clear to you that you need to look for the answer to the question of how to enable USB debugging in the "Settings" item of the main menu. However, the location and method of inclusion are very different. This, as well as the choice of device manufacturer. Let's look at how exactly you can enable USB debugging mode.
Standard option
In firmware where the manufacturer did not try to complicate access to rooting and flashing options, as well as on devices without the possibility of fine diagnostics, Android USB debugging is enabled. In the “Settings” item of the main menu there is a “Development” section in which you need to check the box next to the “USB Debugging” item.
Other firmware version
The location looks similar for firmware with a "close" version. For example, it can be the same “Settings” item, but then the submenu will be called “For Developers”, where you also need to check the debugging option.
Operating system versions 2.2 - 3.0
Here is a more detailed menu, the development item is located at "Settings" - "Applications". Next debug mode USB Android switched on in the same way as described above.
Other firmware
There may be an option when the "Applications" submenu in the "Settings" menu is called "More". The rest is the same as point 3.
Operating system versions 4.2 and later
Here option Android Debugging via USB is deliberately hidden. In order for the activation checkbox to become available, you need to go in, select the “About tablet” item and click on “Build number” about 10 times. After that, the “For Developers” sub-item will appear in the “Settings” menu, where the “USB Debugging” option will become available.
Other location
The item "About the tablet" can be located directly in the "Settings" menu. However, there are versions of operating system assemblies when you need to additionally go to the "System" or "General" submenu. Otherwise, debugging, as in paragraph 5.
PC connection
Before you can use the USB debugging application or the root access utility, you need to properly connect the device to the computer. The first thing that can create an obstacle along the way is the lack of drivers. However, this problem is solvable. For branded devices with non-standard exchange protocols, everything you need can be found on the official websites. In addition, programs phone books, pictures, music from device manufacturers are usually equipped with driver sets. It is enough to install the appropriate utility.
How a good option, you can recommend the MOBILedit Enterprise program, which offers huge selection drivers for all types of equipment. or smartphones from Chinese manufacturers based on MTK processors. If you still can’t install drivers, you should look for them on specialized sites according to the device model and operating system firmware version.
When the drivers are installed, the first connection to the PC will require a confirmation of trust. After setting the appropriate checkbox in the request on the tablet, data exchange will be allowed.
Why do you need debugging?
We briefly list some of the tasks that can be solved using USB debugging:
- , and sections responsible for operating system settings;
- easy file transfer, bypassing the built-in transcoding systems;
- restoration of work after incorrect installation of applications;
- changing the version of the operating system to a newer one;
- changing the firmware to gain access to individual device functions or a language pack;
- getting root (root) rights.
Video on how to enable USB debugging on Android:
It is worth dwelling on the last point in more detail, since rooting is the reason for enabling USB debugging in about 99% of cases.
Why Root Your Tablet or Smartphone?
Root access is, roughly speaking, maximum rights in operating system. They allow you to do backup all contacts, message content, phone history, and information.
By default, Android does not offer . Root access also allows you to change the design: change application icons, system sounds etc. But the most important thing that can be done with such access is to regulate the processes that are loaded into memory.
The operating system is built in such a way that it has an AfterStart event. It can have a whole list of actions, up to the launch of other processes. Often this is showing ads, collecting statistics and other frankly "unnecessary" things. With the help of root rights and small applications, you can flexibly manage the work of both Android as a whole and individual programs.
I doubt that most people know what usb debugging is on android 7.0 in xiaomi phone, HTC, Motorola, Samsung, Sony Xperia,Lenovo LG, Google Nexus etc.
Usually they only find out about it when they find a solution to their problem on the network, where one of the conditions is to enable usb debugging mode, or the system will display something like “device detected, enable usb debugging”.
What does this mean, no one is usually interested - it is necessary, so it is necessary. Turned on and forgot.
However, this feature is already for developers, although without it you will not be able to see or transfer the contents of your phone to a computer or vice versa using a cable, flash it or get superuser rights.
Ordinary smartphone owners do not go further than these functions. Although the term sounds very technical, it is actually very easy to do. This feature is especially relevant for Samsung users.
Of course, you will not program anything, but you will need to quickly reflash the photo - you can find out how to allow the phone to debug via usb by reading the instructions below.
How to enable usb debugging on android 7.0
In the title of the section, I wrote android 7.0, but this applies to all android 7, since there is still 7.1.
In this version special distinctions no, and almost everything is similar to the others, except for the names of some parameters.
In the settings, select "Phone Information" and go to "Software Information", then click until you drop on the "Build Number" line.
Until I drop, of course, I was joking, but the system will tell you when to stop. Next, go back and select the new "Developer Options" section that appears.
After opening, scroll down the page until you see " USB Debugging". Have you screwed it up? Now move the slider and confirm.
Congratulations. You have done everything necessary. Now you can solve your problems or fix problems.
Disable usb debugging mode on android 7 (7.0, 7.1) is simple - move the slider to its previous position (to the left).
It is more difficult to remove the function (section) of the developer. To do this, you will need to reset the settings to factory settings. Good luck.
IN android settings you probably found the mysterious item “USB debugging”, but does everyone know what this mode is for and how to enable it correctly on different versions android OS?
What is debugging for?
Initially, this mode was provided exclusively for developers of applications or services for Android. With the help of debugging, they gained access to the "insides" of the operating system.
But later, more and more cases began to occur when the debugging mode was also needed by "simple" users. It's just that the developers created automated tools for getting root (), restoring a smartphone, modifying the OS that required debug mode.
Despite the formidable name, activating this mode is quite simple.
How to enable debugging
For Android 4.1 and earlier: when the developer menu is visible:
In early Android versions developer options are available in explicit and open form. Just open system settings. In different versions, the developer options section can be located in different places: in the general list, in the "Applications" section, in the main menu.
Select "USB Debugging" and check the box there. You will see a warning pop-up; just click OK.
You do not need to reboot your smartphone to activate this mode.
What to do, if desired section not visible?
In versions of Android since 4.2.2, debug mode (as well as other developer options) is not shown in the menu. However, there is a way to easily open them:
- Open the settings menu and the "General" tab
- Find the "About device" section
- Open the "Software Information" item in it
- Find the line "Build number" in it and tap on it 7 times
- After the notification of becoming a developer appears, return to the "General" section
- Find the item "Developer options" in it.
- Find the line "USB debugging" in this section and check the box there
- Exit the menu
Congratulations, you now have access to your device through your computer!
Cases where debugging saves
Anyone Android user There are situations when debugging is desperately needed. It's good that you used the instructions from the previous section and activated it. Now you can:
- Get root access on your smartphone/tablet using special applications for computer. This requires debugging to be enabled.
- Retrieve data from a device that does not have a display. We devoted a separate article to this problem.
- Restore your device if it won't boot. For this you need to use special utilities, which may differ for different devices and chipsets. Search more detailed information specific to your model.
- To Work with command line on a computer to quickly copy files, install an application or a whole set of applications at once, change access rights to a particular file. To do this, your computer must have adb program(Android Debug Bridge) that allows you to issue commands to the Android environment on the connected device. For her, there is GUI, and the set console commands, which are given through the command line.
In general, if you want to get the most out of the functionality of your Android tablet or smartphone, the debug mode will be extremely useful to you.
