How To Enable USB Debugging On Your Android Phone


Learning how to enable USB debugging mode is critical if you want to do anything useful with your Android Mobile Phone. This tutorial explains how to do it.

Are you interested in creating Android Apps, or maybe just running home diagnostics on your device? If so, one of the first things you’ll want to do is connect your phone to your computer. But to do this, it requires that you set up your phone and enable USB debugging mode accordingly. Let’s enable Debug Mode.

Note: Every manufacturer of Android devices varies. This article was written in 2010 and some things have changed but this should give you an idea of what to look out for.

Debugging Mode for Android

When paired with a computer running Android SDK (or another diagnostic program), Debug Mode can allow you to pull up all sorts of useful information about your phone.  In the screenshot below I’m using the DDMS tool from the Android SDK to monitor where RAM is being used on my Samsung Galaxy S Android phone.  But this is just one example of what you can do!

Enable USB Debugging Mode On Your Android Mobile Phone Device

For older versions of Android please scroll down.

Newer versions of Android (4.0+)

Step 1

Launch the Settings app on your phone.  This app can be found in your App Drawer, or by pressing the menu button on the outside of your device.

launch settings app from androidimagelaunch settings app from menu button on android

Step 2

In the Ice Cream Sandwich (4.0+) or a newer version of the Android OS, the System USB Debugging is now located under Developer Options > Android Debugging.

Before the Developer Options menu will appear, some versions of Android now require that you unlock it by tapping the secret “Build Number” unlock area. This is found under Settings > About Phone> Build Number

unlock developer mode

Done! That’s all there is to enable USB debugging in the new version of Android.

Older versions of Android

The same as above, except after entering the Settings menu you’ll need to enter Applications options.

Android Applications Settings

Next tap Development.

Android Development Applications Settings

Check the box for USB debugging.

You can also Enable, Stay Awake, and Allow mock locations to make things easier when you are running tests.

Android USB Debugging, Stay awake, and Allow mock locations


Your phone should now be in Debug Mode. If you go into the notification bar, you’ll find an Ongoing alert stating USB debugging connected.  Note that even while USB debug mode is enabled you can still Mount your Android phone to your computer to transfer files without causing any problems!

    Thanks for this info! I am using EasyTether Pro and I have a question. Once I check the box for ‘USB Debugging’ do I (and should I) leave this box check alway? Or should I manually check this box every time I go to use my EasyTether Pro app? Is there any danger in leaving the box for ‘USB Debuggin’ always checked?
    Also, why wouldn’t something like USB Debugging be a default feature anyway?
    Thanks for any help and information!

    • grooveDexter

      March 2, 2011 at 8:05 am

      Great feedback! To answer your question, once you check USB Debugging it should remain checked indefinitely. There are a few things that can disable it; certain apps, system updates, and total loss of battery life (in some cases).

      There isn’t any danger in leaving USB debugging mode enabled, but the reason that it isn’t on by default is because it causes a lot of driver issues if you plug it into a computer. You’ll notice while USB debug mode is off that you can easily mount your phone as an external drive, enable (built-in subscription based) tethering, or just have it charge. With Debug mode on, you usually need to download/install an additional driver on your computer if you want to retain the same features.

      USB debug mode also uses up more system resources on the phone, so if you need to use it while it is charging you might notice slower performance. But, most USB-based tethering apps need it enabled because it grants elevated access privileges.

      Hope that helps. Thanks for the groovy question!

    Can someone hack in your phone going through USB debugging. Is that what this is for. Do they need access to your phone to hack in it?

          > i hope by now you have the issue resolved.two years down the line.

          Yes – by buying a new phone with Android 4.1 (not because of the problem with USB debugging but because the old one had too small a memory and a lot of software doesn’t install on the SD card).

          The new phone (Samsung Galaxy S II plus) has USB debugging switched OFF by default, which is what I want. Connecting it to the Win7-PC at home as a hard drive now works fine without having to switch off USB debugging manually every time.

          Unfortunately, at work, where an old XP system without admin rights is installed, the PC does not find a driver for accessing the phone as a hard disk, so I cannot load pictures ONTO the phone (download of pictures still works with some XP-builtin camera app).

      Older versions of Android like 2.3.3:
      Task the following: Enter the Settings menu you’ll need to click Application options. Then click on development;you’ll see debug mode. Click on it….You should get it right now.

    I need a help with my phone Motorola XT531.
    After its Rooted, i could move many apk files to SDcard and create a link file to place in the original folder.
    So using this method was great.
    But I dont remember exactly why, I guess I move motoswitch.apk from system/app and did not create de link to replace it.
    So now i can not access the home and the worst the usb debug is not selected.
    Does anybody know how can I enable it? Or use the to restore just the system/app folder to the original place, because I’ve a original copy of it in the SDCard.

    Hi Austin,

    thanks for the post.

    Like Geoff Berry, I need to switch *OFF* USB Debugging on my Samsung Galaxy Ace in order to connect it as a mass storage device to my PC.

    The problem is that I have to do it every time again, which is a big hassle. Even when I have it switched off, as soon as I plug in the USB cable, it automatically switches on again, and I have to perform all the above steps again.

    Do you know of a way of permanently switching OFF the USB debugging once and for all?

    Thanks in advance.

    Some time ago I was had a problem related some posts above tha was about I got blank screen after I had moved a system file.
    So I asked for help on how to enable the usb debug without use settings menu, off course that was because if I got a blank screen i could not use settings menu.
    So far I don’t know how to enable de usb debug, but the solution were this steps.
    1 – Reset the cellPhone to default factory
    2 – paste the missed file on the sdcard using a PC.
    3 – using another phone send to you a sms and paste a link to an webmail.
    4 – using a PC, send to yourself a link to the file posted on your sdcard described above using the webmail.
    5 – turn on you phone, follow the initial setup screen.
    6 – Your sms will be received and so click on the link, then the webmail will be launched.
    7 – click on the link and select to install the missed file.
    Doing this steps I solve my problems, good look to you.

    For the last few days I have looked at debugging an Android phone or any indormation to connect an android phone. I have an HTC Magic which I received last Christmas from my son. He knows I like gadgets and buttons, it was an introduction to touch phone. I used it until some time in February and then on and off the next couple of months.
    I have a very nice Nokia E5 which does GPS without going online and I can connect to the computer to transfer files and photos to my hearts content.
    Now my needs from a mobile are that I can TXT, phone, take pictures and use the GPS.
    Now the Magic, the camera pixels are less, the GPS you have to go online being Google, yes I can text and phone, but I cannot connect to the computer so I cannot upload Co-pilot which I bought. I have ticked the debug, and the phone tells me the software is up to date.
    I am tempted to do a factory reset, do you know how dangerous that is, should I have the sim card out, it is the same card I use on my Nokia when I am fed up with the Magic.
    By the way I live in rural France where mobile signals are optional, I am not a computer whiz but I get by and I am retired.

    • Austin Krause

      September 13, 2012 at 1:39 pm

      I’m not sure of what you’re tying to do. Co-pilot has a free android app which can be downloaded form the Google Play store. If you are trying to run the co-pilot Windows program on your phone that will not work, it only works on Windows computers.

      If you purchased one of the area-specific premium Co-pilot apps from the Google Play Market, you don’t need USB debugging to transfer it to your phone. It should just be downloadable straight to your device. If the device isn’t listed as compatible, you can try forcing it by just transferring it to your device after mounting the SD.

    I have a Acer Iconia A500, and now i can’t use it because my daughter has locked the device by repeated failures in the income of the pattern.
    Before the blockade, I had turned off the wi-fi and the debug mode is disabled, then i can’t use de ADB commands :-(

    Currently I asked google account to unlock, but as the wi-fi is disabled, the login can’t be done.

    What choice do I have to unlock and get my tablet?

    Note that system upgrades will reset the usb-debugging and make the developer options vanish! If you don’t see the notification on the home screen, that’s prob what happened! You have to start over!
