android studio doesn't see USB connected device

Question

Just to be clear, the device isn't locked or anything and it works perfectly for my friend who has the same android studio version. The problem isn't with detecting the usb device (by the computer), I can access the device's content just perfectly so it connects correctly to my computer but not to android studio. When I try to run an application, the usb device doesn't show amongst the options. Can someone please help me with this issue, knowing that my android studio is updated.

UPDATE: the devices I used are: Samsung J2 and J3

Answer 1

I have the same problem and I use Samsung too.

I fixed it by installing the device driver from Samsung which you can download from Samsung's website

Note

1. You need to enable ADB mode(Like the second comment)

2. You need to set Target in Android Studio to > Open Select Deployment Target Dialog

3. to set Target : Run > Edit Configurations > Targets > Open Select Deployment Target Dialog

Answer 2

Just a Restart of Android Studio worked for me.

In my case it happened because of non-interaction in Android_Studio for long.

Else, Check with Run -> Edit Configurations -> Target.

Answer 3

Have you installed Universal USB Driver, if no then you will not see any device to connect. you can also install individual company device driver.

just try Universal USB Driver to connect all devices

Download from here Universal USB Driver

Answer 6

Open the Device Manager window from the control panel in your computer. In the Others/Unknown Devices tab you would see an unknown android device. Right click on it and update the driver and re-run android studio.
