What is usb android debugging. Enable USB Debugging on an Android Device with a Broken Screen

USB debugging mode is a special feature of Android devices, mainly needed by developers. With its help, you can check the functionality of the application and test it in different situations. But debug mode is also useful for users. Let's consider why it can be useful, how to turn it on and off on Android devices.

Why do you need USB debugging mode on Android OS?

Debug mode allows users to:

• Test the application being developed.
• Get root access to your smartphone or tablet.
• Copy and move files from your Android device to your computer.
• Install a third party downloaded onto your computer (not from Play Market) application for Android.
• Install different versions firmware for the device.
• Restore a broken device.
• Create backup copy files and applications.

In addition, in debug mode you can access system processes and also analyze changes in behavior RAM, processor and other components.

How to enable USB debugging mode on your device

The “Enable USB Debugging” option is located in the “Developer Menu” (or “Developer Options”), which is hidden from users in Android versions above 4.2. But, again, some manufacturers decide to open access to the menu, others decide to hide it. For example, on the company's smartphones Meizu menu developers is always open and is located in the “ Accessibility", and on Samsung devices access to the menu is closed. It all depends not only on the company, but also on specific model devices.

So, if access to the developer menu is blocked on your device, do the following: in the device settings, open the “About device” tab and click on the “Build number” item until a notification appears that you have been assigned developer status and you can use the special menu.

Now go to this menu. Depending on the model, the menu entry may be located in different sections of the settings menu. Either in the device settings there may immediately be a section “For Developers” (“Developer Options”, “Developer Menu”), or it may be a subsection of the items “Accessibility”, “Other”, “More”, “Advanced Settings”.

When you enter the developer menu, check the box next to “Enable USB debugging” (or “USB debugging mode”). Usually this item comes first.

Where is the mode located in different versions of Android (photo gallery)

The developer menu is located in the “More” section. In Android 2.2–3.0, the “USB Debugging” item is located in the “Applications” section. In Android 4.2 and higher, the developer menu is moved to the “Settings” section

How to enable USB debugging mode if this cannot be done from the device

There are ways to enable debugging mode even if this cannot be done on the device itself due to, for example, a broken screen, a broken touchscreen, or problems with the device as a whole.

The main condition: your device must already have a third-party Recovery installed - CWM or TWRP. This is necessary to be able to gain full root access to the operating system.

After the reboot, you can work with your smartphone or tablet using QtADB, MyPhoneExplorer, ADB and other similar programs. That is, using USB debugging mode.

What to do if nothing works

To work with USB debugging, special ADB drivers are used (Android Debug Bridge, literally “bridge for Android debugging"), which can be downloaded from the Google website, official page located at: https://developer.android.com/studio/index.html. Let's figure out what to do if ADB does not detect the device, why it is impossible to use USB debugging mode.

Make sure mobile device detected by computer. To do this:

1. Check the USB cable for damage. Pay special attention to strong bends and sections of the cable near the plugs, where connecting wires often break. Try using a different cable to connect. If the problem is truly a physical defect, replace the cable.
2. Try plugging the plug into a different USB port on your computer. It is advisable to use the ports on the back side system unit, since the rear ports are located directly on motherboard. The front USB ports are not always connected correctly, which is what causes the problem.
3. Try connecting your Android device to another computer. Sometimes it happens that a particular PC incorrectly recognizes a smartphone or tablet and does not read the necessary data from it. If the device is recognized correctly on another computer, take your PC for repair and explain the problem, since the causes of problems may be different.
4. Try disconnecting all USB devices from your computer. Some of them may prevent your smartphone or tablet from connecting normally to your PC.

Make sure you use official firmware device manufacturer. If you have installed third-party firmware on your smartphone or tablet (such as CyanogenMod or similar), then USB debugging may not work correctly.

Make sure you have installed the correct ADB drivers. There are different versions of drivers for different devices. All of them are distributed according to smartphone and tablet models on the official website. There is also universal ADB drivers, but it is better to use them only if there is no separate driver for your device, since universal drivers There may be connection issues that can only be resolved by contacting Google Support.

It is better for software developers to use not separate ADB drivers, but a system Android Studio, which can also be downloaded from the official website: developer.android.com. In Android Studio, driver configuration occurs automatically; in addition, there is Android emulator for a computer, so USB debugging may not be necessary.

How to turn off USB debugging

To disable USB debugging mode on Android devices, open the Developer Menu and uncheck the Use USB Debugging option.

USB debugging mode - extremely useful tool not only for software developers, but also for ordinary users operating room Android systems. With its help, you can install and reinstall firmware on your mobile devices, move files from your smartphone or tablet to your computer, download to Android third party applications. The ability to use USB debugging mode is also useful in cases where the device has stopped working correctly, as it allows you to delve into system processes, which will help you find problems and malfunctions. And in addition, USB debugging will help you gain root access to the device, which will significantly expand the capabilities operating system.

I doubt that most people know what USB debugging is on Android 7.0 xiaomi phone, HTC, Motorola, Samsung, Sony Xperia, Lenovo LG, Google Nexus and so on.

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.”

No one is usually interested in what this means – it has to be done, it has to be done. Turned it on and forgot it.

However, this function 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 the firmware or gain superuser rights.

Ordinary smartphone owners go no further than these functions. Although the term sounds very technical, it is actually very simple to do. This feature is especially relevant for Samsung users.

Of course, you won’t be programming anything, but you’ll need to quickly reflash and transfer photos - you can find out how to allow your phone to do USB debugging 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 also 7.1.

There are no special differences in this version and almost everything is the same as the others, with the exception of 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.

Of course, I was joking until I dropped, but the system will tell you when to stop. Next, go back and select the new “Developer Options” section that appears.

Congratulations. You have done everything necessary. Now you can solve your problems or fix problems.

It is more difficult to remove a developer function (section). To do this, you will need to reset the settings to factory defaults. Good luck.

On any smartphone or tablet computer running on the Android platform, regardless of its manufacturer and pre-installed OS version, it is possible to enable special function, which is called “Debug Mode”. However, the process for activating this functionality varies. The fact is that it all depends on the version of the installed system.

In this article we will take a closer look at the question of how to enable USB debugging on Android, as on earlier versions OS, and on the latest ones. We will also look at the question of what tasks this mode is intended to solve.

Let's first figure out for what purposes the average user may need to activate this mode.

As you might guess, it is necessary for debugging applications and the devices themselves. Speaking more in simple language, is intended for checking the functionality of programs, and therefore is very popular, first of all, among software developers. However, for mere mortals it is also valuable, since it allows you to interact with Android via a PC and use programs (primarily ADB) that can remotely carry out various manipulations with the device.

Activation procedure on different versions

Sometimes it becomes necessary to connect a smartphone with an Android system to a computer, conduct diagnostics or general testing. To do this, you need to enable USB debugging mode. This mode is intended exclusively for developers and runs without a connected USB cable. Let us immediately note that the procedure does not require a deep understanding of the technical principles of the gadgets’ operation and can be performed even by beginners. Before we begin, I would like to note that USB debugging is much preferable to testing the device on a computer emulator.

How to enable USB debugging

To enable debugging for this:

1. Enter the menu of your smartphone;
2. Enter the settings item;
3. Go to “developer options”;
4. Check the box next to “USB Debugging”.

Often users encounter the problem that they cannot enable debugging on Android platform 4.2 because there is no developer mode in the settings. It is unknown why, the manufacturer decided to make it deliberately hidden (probably so that regular user There was no desire to once again tinker with the settings and do unnecessary dirty tricks).

But this is not a problem for us and we can easily bypass this barrier:

1. Go to the section about the device;
2. Click 10 times on the build number (after this you will see a message that you have become a developer).

This method works on almost all stock (store) firmware. This is also possible on smartphones Samsung Galaxy S4
