What Is USB Debugging Mode On Android? [MakeUseOf Explains]

usb debuggingIf you use an Android phone and you’ve searched forums for solutions to problems, you’ve probably heard the term “USB Debugging” every once in a while. You may even have seen it while looking through your phone’s settings. It sounds like a high-tech option, but it really isn’t; it’s quite simple and useful.
One beauty of Android is that it has a lot of built-in features, many of which are advanced. If you want to supercharge your phone with mods and whatnot, you can; if you want to use it just as it was out of the box, you can ignore the advanced stuff. USB Debugging is a feature that all users can benefit from, though, so you should know what it does and when to use it.
What Is USB Debugging Mode?
USB Debugging Mode is a mode that can be enabled in Android after connecting the device directly to a computer with a USB cable. The primary function of this mode is to facilitate a connection between an Android device and a computer with Android SDK (software development kit). As the name might suggest, Android SDK is a software suite that’s designed to aid in the development of Android apps.
Ever wondered how a programmer creates apps on the Android? They definitely don’t code them straight on the phone device! That would be nightmarish at best. Instead, they utilize the environment of the Android SDK to code apps on a computer, use USB Debugging Mode to transfer those apps to a device for testing.

But, again, here’s the takeaway: USB Debugging Mode establishes a direct connection between an Android device and a computer and readies it for deeper-level actions. That’s the important part.
In some versions of Android, the USB Debugging Mode feature may be called Developer Mode. With such a name, it can be easy (and reasonable) to think that you’ll never need to deal with this aspect of Android if you never plan on developing anything. That’s not exactly true.
Why Is USB Debugging Mode Important?
USB Debugging grants you a level of access to your device. This level of access is important when you need system-level clearance, such as when coding a new app. However, there are a few non-development-related benefits from this new level of access that can give you much more freedom of control over your device.
For example, with Android SDK, you gain direct access to your phone through your computer and that allows you to do things you normally couldn’t, like snag instant screenshots of your device or run terminal commands with ADB. These terminal commands can help you restore a bricked phone–a useful tool for any adventurous Android owner. Without it, you’d have to get a replacement phone.

USB Debugging is also necessary if you ever want to root your Android device. Before an app like One-Click Root can dig into your system and deliver the exploit that roots the device, USB Debugging is necessary to allow that function in the first place.
Yes, the original intention for USB Debugging Mode was only meant for developers who needed to copy data between their computers and Android devices, to install apps on the phone without notifications, and to read log data off the phone. But even if you aren’t a developer, you’ll probably run into a few apps that require USB Debugging Mode to function properly, so this mode does affect you and you should know about it.

Start searching dialer codes for Samsung devices and do be careful on what you do in those service menus.
-sent from this device using this app.

Just tried that and cant get any codes to work in the dialer or in the apps.. and one says im missing su so i dont know im about to just flash back to the older firmware Security is nice and all but damn they killed it.

I found the problem it was samsung knox if you activate it or use my knox app it disables your dev settings so i ripped knox out of my phone now i have usb debugging..

[Q] [HELP] NEXUS 4 - Cracked Screen\Digitizer - Android KitKat? Access Files

Hi,
I realize that there might be an answer to this already, however I have been searching for a while and no such answer has presented itself. I have come across other threads on this forum that explain how to get in. However my concern is that these are really old posts and perhaps point to an older version of Android?!? The reason I didn't follow those tutorials is I am afraid of wiping off any data that might exist on the phone (which is not something I would like to do!!!)
So it is as follows:
LG NEXUS 4 - 02 NETWORK UK
NOT ROOTED
STOCK EVERYTHING
USB DEBUGGING DISABLED
CRACKED SCREEN\DIGITZER - NO TOUCH RESPONSES ACCEPTED
So my question is this, can I access the files on here including all music/photos/contacts/messages etc and back up to a WINDOWS PC. Please forgive me if my responses sound noobish to you, as I am not familiar with Android, so might ask some daft questions.
Thanks in Advance
Anybody? I fear for trying anything as I do not wish to loose pictures etc.
Stock Everything
Not Rooted
No USB Debugging Enabled
Can I enable usb debugging through adb?
you do not need usb debugging enabled to transfer data from device to pc, my question is, when you plug your device into your pc, does your computer recognize it as a mass storage device and can you see your phone in the list of devices with removable storage ?

[Q] Broken display - no debugging... Help accessing please!

Hi all, can anyone help? I smashed my phone at the weekend and really want to get back in to it if only to turn on contacts sync and see who keeps texting me, but for some reason USB debugging isn't on. Phone is stock.
Plugging in with USB = recognised in device manager as Xperia Z3. I've tried to download Android SDK, and install the USB drivers from the Sony website (says best driver already installed - the ones from the Sony website don't have any kind of installation program so not sure what I'm supposed to do with them!).
I know this isn't easy but can anyone guide me through getting in to it and getting USB debugging on so I can use Android Control? It seems I need to get the phone in to recovery mode so that it automatically enables USB debugging? If I hold down power/volume up a few times or in a weird combination, the LED goes blue and the phone comes up in device manager as 's1boot' and then 's1boot fastboot'. I've tried installing the drivers I've found from DooMLoRD but they don't help me access the phone at all, it still says unable to find the device. adb devices from the adb folder command prompt says no devices (i presume because USB debugging still disabled). I feel like I have made progress but need a bit more progress still to get in, if it is at all possible!
New thread because I can't find anyone with a Sony Xperia Z3 trying this, with the same steps taken/blue LED etc.
USB OTG+ USB mouse
Try to use USB OTG+USB mouse, that did the trick for me
no display whatsoever... so having a mouse isn't going to help me sadly! unless i can get the screen displayed on a computer monitor or something?

[TPLink C5S and 'Minimal adb and fastboot'-package]How to activate the phone

Hello,
first of all I'm not the man who can make a new and highly 'must have' app for my device. I only have a problem but it seems only one of you can help me on it.
I wanted to use an usb-otg-device (camera) on my cell phone but it doesn't work. I found out that usb-otg is the problem (I even didn't know before that it exists) becaus it is not activated on my device. So I wanted to try out how to change this. Information on otg is hard to find since the community mostly seems to assume that all cell phones out there have this feature and a special cable is needed so all answers on such a question goes on this cable. I just not able to find out which devices allready have this (it is not mentioned) and I have the evidence that not all types of cell phones to be sold nowadays have it ... my smart phone I have.
So I wanted to see if I was able to make my phone have this feature by hacking the os on it. Now we will come to adb from the package. I wanted to see if the proper module for the kernel is anywhere there and how to make the device loading it at boot. I just don't know if the usb curcuit is able to do it this way but without the proper driver it's not important. And if the driver is loaded and it works not anyway I really have a problem. But first of all I have to activate the driver (hoping it is allready able to work with a curcuit with no otg ... just as the normal driver; a thing I have to find out too). But the first thing I have to do is to find out what is happening at boot, which is the design and options the kernel uses and so on.
But now my new problem: adb shows an empty list of devices at the pc even the driver has sounded at install. The cell phone is set for developers and usb debugging is on. I plugged it of and on and start 'Minimal adb and fastboot' the device is not plugged in and also with the device allready connected but that is no defference ... adb devices shows an empty list.
So: How can I access my cell phone?
Thanks and excuse me if this is allready answered ... I didn't found any thread

Samsung S7 Edge ADB Commands

Hi,
Basically I have a Samsung S7 Edge (SM-G935F) which the screen is completely smashed on (no display no touch). When I connect it to the PC it detects the phone but it doesn't show the folders inside (can only assume its got a prompt to accept PC or USB debugging isn't enabled).
After a lot of testing with OTG cables keyboards/mouse etc the furthest I got was putting the phone into Recovery Mode (PWR, VOL UP & HOME) then selected APPLY UPDATE ADB.
When I run the ADB in Powershell and run "adb devices" it finds the device ID and says "sideload".
Is there any command I can run to pull the files off my internal DCIM folder (thats all I really need)?
I did read up the only way this could be possible is to install a custom rom (TWP with ODIN?) and then pull files off.
Is this possible and would installing a custom rom delete my internal files as that would render this pointless.
Sorry im new to a lot of this so all my knowledge is just what ive read recently.
Thanks
1. To pull user data USB-debugging must got enabled. May be this method works for you to enable it:
2. To flash TWRP it's required device's bootloader got unlocked - what requires OEM unlock must got enabled . Note: Unlocking bootloader erases all user data.

Thanks for the reply,
Ok so my only option is the "blind" method.
I have the app installed via Google Play Store on my PC to the device however when I hold down the home button to ask google I hear no reply from her, is there any hotkey to use for this device to ask google or any alternative methods to open this app?
I can see the S7 Edge is connected to my WIFI as it shows on the Sky Hub and IPScanner.
Also is there a way to tell what android interface version I have so I can follow someone on Youtube going into Settings or Apps etc to open the app.
I feel like I am so close to getting these photos off the phone but its just a blind guess at the moment.
I managed to get a hold of a friends S7 Edge, using this I mapped out some keyboard functions to turn on developers options then usb debuggings.
What I have noticed is now when I connect the phone via USB to the PC and run ADB DEVICES it shows up the ID then unauthorised as the status, so I can only assume this means I have USB DEBUGGING ENABLED.
Is this correct?
If so why when I open the Samsung Galaxy in Windows does it still not show the folders, is there another setting I need to turn on/off?

I want the internal storage contents of DCIM on the phone.
I followed the steps on my "donor" phone to go into Developer Options > USB Configuration > MTP but all that happens is the phone detects on Windows but wont show me the contents of it.
I also tried changing to PTP but same issue.
I know there is a pop-up that shows on the phone asking to ALLOW THE PC TO ACCESS FILES but I cannot have the USB DATA CABLE and OTG/KEYBOARD plugged in at the same time (and I also tried two OTG adapters both came up MOISTURE DETECTED when using).
So unless anyone knows of a OTG SPLITTER that 100% works with S7 EDGE then I need to find a way to either bypass the ALLOW MESSAGE or manually add my PC to its allow list.

fully charge your phone and hopefully the heat generated from charging process remove the moisture detected warning or you can also use hair blower to heat your charging port area
also don't put your device on microwave oven unless you want to see some fireworks

[APP][8.0.0+][ROOT] Start ADB Over Wi-Fi [Root]

Hi , I have made an app that enables you to connect 2 your phone wirelessly, using ADB. The app opens port tcp port 4774 n showcasesthe command needed to connect the device, the app also showcases the devices IP so you don't have to look it up, root is required 4 the root method. There are also premium versions available which remove adds, two are obtainable UnLockKkAyyy which should also unlock any other apps w/ it in the description, if they ever might be released n Start ADB Over Wi-Fi Unlocker which should only unlock this app.
Google play LiNKs:
Start ADB Over Wi-Fi [Root]​
Start ADB Over Wi-Fi Unlocker​
UnLockKkAyyy​
This should be about it for now .

What's great is the OP is helping people connect rooted Android to PC adb completely wirelessly (without the initial need for the USB cable), where I'd like to ask the kind-hearted developer if he knows of a Windows PC networking command that we can run from the PC which tells us which port is being used for that adb connection.
More details on WHY I ask that question are over here...
[adb,scrcpy,vysor] What ports does Android 12 randomly set when Wi-Fi connecting via Wireless debugging adb "pair" or "connect" commands?
Bearing in mind I'm NOT ROOTED (and my phone can't be rooted); so that's why I ask for help in determining the random Developer options Wireless debugging port after the fact...
I think I am missing the point of this app. Isn't ADB over WiFI a standard feature of android, under developer options?

The first post is from 2021, I definitely basically have used it well before that. However I do use custom ROMs. And as I implied it’s already there. One of the big concepts of Android OS is to use what’s there, not add on , which is basically a duplication.
