Scrcpy: adb: error: failed to get feature set: more than one device/emulator

[dxwoodward]

• [x] I have read the FAQ.
• [x] I have searched in existing issues.

Environment

• OS: [Windows]
• scrcpy version: [e.g. 1.13]
• installation method: [Windows Zip]
• device model: Samsung Galaxy S10
• Android version: [10]

I read somewhere that adb.exe stays running in the background when you close your session. However It's preventing me from starting a new session until i close out of adb.exe from task manager. I never had this issue back on version 1.12, so I wanted to bring it up here.

The only way I can get the session started is by going to task manager and manually ending the adb.exe process and starting fresh.

Does anyone know a fix to this?

What is the result of adb devices?

[dxwoodward]

This is the result.

List of devices attached
R58**GV device (my Android)
emulator-5566 offline

Then you have 2 devices listed (including an emulator).

You must pass the serial of the device (like for any adb command):

scrcpy -s R58******GV

Thank you, That did the trick. I was used to opening scrcpy from the .exe in the folder. Now I'll just have to open up cmd and type what you suggested (after navigating to the folder that is) and get there the old fashioned way.

I wonder what the emulator-5566 device is and why it starts up when I freshly open up scrcpy.exe.
