Samsung S7 root after connecting Android Studio display Unknown device?

the main reason for asking here is that there are more programmers and more android.

adb can detect the device:

android studio:

appapp
:



cannot run, which is embarrassing.
I don"t know if I have any experience, please let me know how to solve it. Thank you.


is my influence after root. I just tried `adb shell getprop | grep abi, shows that permission is denied.
then I tried other commands and found that adb does not have file permissions in the root directory.

then I removed the Root permission in SuperSU. After the phone restarts, root permissions disappear and adb becomes available again.

android studio re-identified my mobile phone
