  • Can you confirm that usb debugging is enabled? Can you confirm that usb debugging is authorized? – Marius Kaunietis Dec 22 '15 at 10:42
  • Do you have Developer options enabled on those devices? – J Whitfield Dec 22 '15 at 10:43
  • Also, please include `adb devices` command output. – Marius Kaunietis Dec 22 '15 at 10:44
  • @MariusKaunietis as I add in the edit yes in my first phone the debugging is authorize(developer options) and please can you explain how to show you the ocmmand output – Moudiz Dec 22 '15 at 10:49
  • I assume you use Windows. First, locate a file named `adb.exe`, which should be in `/platform-tools/`. Then right click in the directory and choose "open command prompt window here", then type in `adb.exe devices` (not sure if you need .exe, I hardly ever use windows for anything other than gaming). – Marius Kaunietis Dec 22 '15 at 10:57
  • @MariusKaunietis I richt clicked on it but i didnt have open command prompt window here , by the way I tried another phon and the degugin is authorised but still the adb not reading it – Moudiz Dec 22 '15 at 11:08
  • Try these steps to open Command Prompt window: http://www.sevenforums.com/tutorials/27778-open-command-window-here.html – Marius Kaunietis Dec 22 '15 at 11:13
  • do you want to past all the result ? btw if i run adb devices its not shoing anything – Moudiz Dec 22 '15 at 11:18
  • I have done some development work on a Samsung Galaxy Note, and I noticed that sometimes I had to fudge around with the phone to get it to recognize the USB connection. This could be why sometimes it seems to be working for you, but others it does not. – Tim Biegeleisen Dec 22 '15 at 15:16
  • so what should I do to start working ? @TimBiegeleisen – Moudiz Dec 22 '15 at 15:19
  • What worked for me was unplugging the USB cable from the phone and then plugging it back in. If this works for you, I will post it as a formal answer. – Tim Biegeleisen Dec 22 '15 at 15:21
  • i wish if this is a solution, no unfortunetly it didnt work @TimBiegeleisen – Moudiz Dec 22 '15 at 15:23
  • The Note phone should show a popup dialog box asking you to OK connecting it as a USB device. If you don't see this, then it's not connected. This is not a problem with Android Studio, despite the appearance of it. – Tim Biegeleisen Dec 22 '15 at 15:25
  • @TimBiegeleisen it never popup on my phone to ask if usb to connect , even before when it was working it didnt ask that. when i connect it to usb, i can access images and other thing in my phon – Moudiz Dec 22 '15 at 15:28
  • Accessing images and "other things" may use a totally different driver than the one needed for deploying apps on your phone from Android Studio. In any case, I may not be able to help you any further. – Tim Biegeleisen Dec 22 '15 at 15:30
  • @TimBiegeleisen I am installing the driver from samsung http://developer.samsung.com/technical-doc/view.do?v=T000000117 i dont know if i have any other choice – Moudiz Dec 22 '15 at 15:33
  • @Moudiz General comment: It's _really_ bad form to go around peppering everyone's questions and answers with many comments. Try to avoid this in the future, thanks. – Tim Biegeleisen Dec 22 '15 at 15:44

make sure the usb driver for the phone is installed correctly,you can check in device manager.

Here is a link to the Samsung technical spec for the USB driver.

  • I can access the images and folders of the phone , does that mean its is installed correctly ?, also in the device manager I didnt notice any unistalled devices – Moudiz Dec 22 '15 at 10:48
  • if there are no errors in device manager then the device is probably properly installed. this happens to me from time to time and what i do to resolve the issue is turn off developer options on my device, restart android studio and then turn developer options back on. – Gareth Price Dec 22 '15 at 11:07
  • go to the devices settings and find developer options then there should be a toggle button to turn the options on/off – Gareth Price Dec 22 '15 at 11:11
  • add this link in your question http://developer.samsung.com/technical-doc/view.do?v=T000000117 – Moudiz Dec 22 '15 at 15:37

  • Please, at least summarize the main steps taken from that url instead of just copy/pasting a link to an external resource. – eventHandler Oct 03 '17 at 23:38

  • Supposing you are using Windows OS for development. Check the Device Manager by right clicking My Computer and then Manage..Check the drivers are installed or not. – JItesh SUvarna Dec 23 '15 at 06:00
