How to Fix Android Not Detected in ADB

The role of ADB (Android Debug Bridge) is very high on the phone. It can be used to do many things, such as installing or uninstalling apps, resetting the phone, or even flashing.

Checking the device is connected or not using the command adb devices. But there are times when the phone can’t connect. Either it pops up a notification “unauthorized” or even the phone doesn’t appear on the list at all.

If the phone ID doesn’t show up at all, then I can confirm that the problem is caused by drivers the phone is not installed on the computer. Meanwhile, if the problem is a notification appears unauthorizedthen it means the phone haven’t confirmed permissions that appear on his phone.

Android Phone Not Detected in ADB Solusi

The solution will be divided into two parts according to the constraints as I mentioned above. So please apply the steps below according to the constraints you are experiencing.

1. Phone ID Not Detected on ADB Devices

ADB Not Detecting Android Device

As I explained a little above that this problem is caused by an uninstalled cellphone driver. So all you need to do is install drivers it on his computer.

To find drivers according to their cellphones, you can go through Google or the official website of the cellphone brand. Or you can also get it from the community/forum that discusses the cellphone, for example from Facebook Group.

After the driver is successfully installed, it is highly recommended to restart the computer and after that try again to check the device on ADB. It must have been detected properly by now.

2. Appears Unauthorized on Mobile ID in ADB

If it appears “Unauthorized“, of course the ADB command will not be responded to on the cellphone. That’s because the phone has not approved the ADB permission. And to overcome this is very easy, please follow the steps below:

  1. Disconnect the USB cable connected from the phone to the computer.

  2. Then open Settings on your phone.

  3. Tap menu Developer Options (Developer Mode).

  4. Scroll down and tap on options Revoke USB debugging authorization.

  5. If a dialog appears, just tap on the option OK.

  6. Now reconnect the USB cable to the computer.

  7. On the computer, type the following command to stop ADB:

    adb kill-server

    And after that use the command below to start the ADB process and detect the phone:

    adb devices
  8. Then a confirmation dialog will appear on the cellphone, please tap Izinkan.

  9. Done, now the phone must have been detected in ADB.

If you switch to another computer, it may be necessary to perform the above steps again so that later the phone can be detected in ADB. Because if you don’t revoke the USB debugging authorization, the confirmation dialog or ADB permissions won’t appear on the phone.

The final word

Of the many cases, the two things I mentioned above are problems that often occur. Although the solution is a little complicated, but at least it works 100%.

And one more thing, if you have installed the appropriate driver but ADB has not been able to detect the cellphone, please check the driver via “Device Manager‘ on his computer. If a yellow exclamation mark appears, please update the driver so that it can function properly.

Hopefully useful and good luck
